|---|---|
| The Brinsmere Fund - Growth ETF | Commodities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Commodities Risk. The Fund may invest in underlying funds that principally invest in commodity-linked derivative instruments, the value of which may be affected by price movements of the underlying commodity, changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, and tariffs. The prices of industrial metals, precious metals, agriculture, and livestock commodities may fluctuate widely due to factors such as changes in value, supply and demand, and governmental regulatory policies. |
| The Brinsmere Fund - Growth ETF | Cybersecurity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets or proprietary information, or cause the Fund, the Adviser, the Fund’s sub-adviser, Penserra Capital Management LLC (the “Sub-Adviser”), and/or other service providers (including custodians and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Sub-Adviser or the Fund’s other service providers, market makers, Authorized Participants (“APs”), the Fund’s primary listing exchange, or the issuers of securities in which the Fund invests have the ability to disrupt and negatively affect the Fund’s business operations, including the ability to purchase and sell Shares, potentially resulting in financial losses to the Fund and its shareholders. |
| The Brinsmere Fund - Growth ETF | Emerging Markets Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. The Fund may invest in underlying funds that principally invest in companies organized in emerging market nations. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value. |
| The Brinsmere Fund - Growth ETF | Equity Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. The equity securities held in the Fund’s portfolio through the underlying funds may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| The Brinsmere Fund - Growth ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| The Brinsmere Fund - Growth ETF | ETF Risks, Authorized Participants, Market Makers, And Liquidity Providers Concentration Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| The Brinsmere Fund - Growth ETF | ETF Risks, Costs Of Buying Or Selling Shares Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. |
| The Brinsmere Fund - Growth ETF | ETF Risks, Shares May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. |
| The Brinsmere Fund - Growth ETF | ETF Risks, Trading Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares. |
| The Brinsmere Fund - Growth ETF | Fixed Income Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Securities Risk. The value of the Fund’s investments in fixed income securities held through the underlying funds will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities. On the other hand, if rates fall, the value of fixed income securities generally increases. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets. Credit risk refers to the possibility that the issuer of a security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation. |
| The Brinsmere Fund - Growth ETF | Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk. The Fund may invest in underlying funds that invest primarily in foreign securities. Investments in foreign securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in foreign securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in foreign securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. These risks may be enhanced for securities of companies organized in emerging market nations. |
| The Brinsmere Fund - Growth ETF | Futures Contracts Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Futures Contracts Risks. A decision as to whether, when, and how to use futures involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the risks associated with all derivatives, the prices of futures can be highly volatile, using futures can lower total return, and the potential loss from futures can exceed the Fund’s initial investment in such contracts and could be unlimited. |
| The Brinsmere Fund - Growth ETF | Gold Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Gold Investing Risk. The Fund may invest in underlying funds with significant exposure to gold through certain commodity-linked derivative instruments, such as gold futures contracts, as well as exchange-traded products backed by or linked to physical gold (“Gold ETPs”). The value of commodities, such as gold, typically is based upon the price movements of the physical commodity or an economic variable linked to such price movements. Price movements in gold, gold futures contracts, and Gold ETPs may fluctuate quickly and dramatically. Some factors that impact the price of gold, gold futures contracts, and Gold ETPs include, but are not limited to, overall market movements, changes in interest rates, changes in the global supply and demand for gold, the quantity of gold imports and exports, factors that impact gold production, such as drought, floods and weather conditions, technological advances in the processing and mining of gold, an increase in the hedging of precious metals, such as gold, and changes in economic and/or political conditions, including regulatory developments. |
| The Brinsmere Fund - Growth ETF | Government Obligations Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Government Obligations Risk. The Fund may invest in underlying funds that invest primarily in government obligations. No assurance can be given that the U.S. government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law, such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Securities issued by Fannie Mae and Freddie Mac have historically been supported only by the discretionary authority of the U.S. government. While the U.S. government provides financial support to various U.S. government-sponsored agencies and instrumentalities, such as Fannie Mae and Freddie Mac, no assurance can be given that it will always do so. |
| The Brinsmere Fund - Growth ETF | Inverse Bond Strategies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Inverse Bond Strategies Risk. The Fund may invest in underlying funds that seek to perform, on a daily basis, opposite the daily price movement of the U.S. bond market. Such underlying funds may invest to a significant extent in derivative instruments and be subject to compounding risk and leverage risk, and there is no guarantee that such underlying funds will successfully achieve their objectives. |
| The Brinsmere Fund - Growth ETF | Investment Company Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Company Risk. The risks of investing in investment companies, such as the underlying funds, typically reflect the risks of the types of instruments in which the investment companies invest. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other investment company. Investments in ETFs are also subject to the “ETF Risks” described above. |
| The Brinsmere Fund - Growth ETF | Managed Futures Strategies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Managed Futures Strategies Risk. The Fund may invest in underlying funds that utilize various investments strategies that involve the use of complex investment techniques, such as a managed futures investment strategy, and there is no guarantee that these strategies will succeed. The use of such strategies and techniques may subject the underlying fund to greater volatility and loss. |
| The Brinsmere Fund - Growth ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund. |
| The Brinsmere Fund - Growth ETF | Market Capitalization Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Capitalization Risk. ◦Large-Capitalization Investing Risk. The Fund may invest in underlying funds that invest in the securities of large-capitalization companies. . The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. ◦Mid-Capitalization Investing Risk. The Fund may invest in underlying funds that invest in the securities of mid-capitalization companies. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole. Mid-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings. ◦Small-Capitalization Investing Risk. The Fund may invest in underlying funds that invest in the securities of small-capitalization companies. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

| The Brinsmere Fund - Growth ETF | Market Capitalization Risk, Mid-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid-Capitalization Investing Risk. The Fund may invest in underlying funds that invest in the securities of mid-capitalization companies. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion.

| The Brinsmere Fund - Growth ETF | Market Capitalization Risk, Small-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small-Capitalization Investing Risk. The Fund may invest in underlying funds that invest in the securities of small-capitalization companies. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings. |
| The Brinsmere Fund - Growth ETF | Models And Data Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Models and Data Risk. The composition of the Fund is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to securities being included in or excluded from the Fund that would have been excluded or included had the Models and Data been correct and complete. |
| The Brinsmere Fund - Growth ETF | Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Options Risk. The Fund may invest in underlying funds that utilize options strategies. Purchasing and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable an underlying fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the underlying fund. The underlying fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the adviser to an underlying fund fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. An underlying fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the underlying fund writes the option and the date on which the underlying fund purchases an offsetting position or exits the option. |
| The Brinsmere Fund - Growth ETF | Portfolio Turnover Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk. The Fund may trade all or a significant portion of the securities in its portfolio in connection with each rebalance and reconstitution of its Index. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains. |
| The Brinsmere Fund - Growth ETF | Real Estate Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Real Estate Sector Risk. The risks related to investments in real estate securities include, but are not limited to, adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations, or interest rates; operating or developmental expenses and lack of available financing. |
| The Brinsmere Fund - Growth ETF | REIT Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Investment Risk. The Fund may invest in underlying funds that invest primarily in REITs. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income. |
| The Brinsmere Fund - Growth ETF | Specialty Credit Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Specialty Credit Risk. The Fund may invest in underlying funds that have exposure to specialty credit, a subset of the private credit market. Specialty credit refers to the private credit market that extends beyond traditional corporate lending. Specialty credit loans are secured by specific, tangible or financial collateral as opposed to a borrower’s overall corporate earnings. Investments in specialty credit are not traded in public markets, are illiquid, can be subject to various restrictions on resale, and there can be no assurance that an underlying fund will be able to realize the value of such investments in a timely manner. Additionally, specialty credit investments can range in credit quality depending on security-specific factors, including total leverage, amount of leverage senior to the security in question, variability in the issuer’s cash flows, the size of the issuer, the quality of assets securing debt and the degree to which such assets cover the subject company’s debt obligations. The companies in which an underlying fund invests directly or indirectly may be leveraged, often as a result of leveraged buyouts or other recapitalization transactions, and often will not be rated by national credit rating agencies. |
| The Brinsmere Fund - Growth ETF | Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tax Risk. The contribution of the initial assets of the Fund was structured as a transaction in which no gain or loss was intended to be recognized for U.S. federal income tax purposes, however, there are no assurances that the Internal Revenue Service (the “IRS”) will agree that such contribution qualifies for nonrecognition. If the contribution did not qualify as a nonrecognition transaction for U.S. federal income tax purposes, such treatment could affect the Fund’s ability to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”), and affect whether gains and losses recognized by the Fund are treated as ordinary income or capital gain and potentially cause the Fund to be subject to income or excise taxes for under distributions. In turn, such treatment may also affect the amount, timing or character of income distributed to you by the Fund such that the Fund may be required to reclassify distributions previously distributed to you. |
| The Brinsmere Fund - Growth ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. |
| The Brinsmere Fund - Conservative ETF | Commodities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Commodities Risk. The Fund may invest in underlying funds that principally invest in commodity-linked derivative instruments, the value of which may be affected by price movements of the underlying commodity, changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, and tariffs. The prices of industrial metals, precious metals, agriculture, and livestock commodities may fluctuate widely due to factors such as changes in value, supply and demand, and governmental regulatory policies. |
| The Brinsmere Fund - Conservative ETF | Cybersecurity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets or proprietary information, or cause the Fund, the Adviser, the Fund’s sub-adviser, Penserra Capital Management LLC (the “Sub-Adviser”) and/or other service providers (including custodians and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Sub-Adviser or the Fund’s other service providers, market makers, Authorized Participants (“APs”), the Fund’s primary listing exchange, or the issuers of securities in which the Fund invests have the ability to disrupt and negatively affect the Fund’s business operations, including the ability to purchase and sell Shares, potentially resulting in financial losses to the Fund and its shareholders. |
| The Brinsmere Fund - Conservative ETF | Emerging Markets Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. The Fund may invest in underlying funds that principally invest in companies organized in emerging market nations. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value. |
| The Brinsmere Fund - Conservative ETF | Equity Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. The equity securities held in the Fund’s portfolio through the underlying funds may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |

| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

These risks may be enhanced for securities of companies organized in emerging market nations. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Futures Contracts Risks. A decision as to whether, when, and how to use futures involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

| The Brinsmere Fund - Conservative ETF | Gold Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •Gold Investing Risk. The Fund may invest in underlying funds with significant exposure to gold through certain commodity-linked derivative instruments, such as gold futures contracts, as well as exchange-traded products backed by or linked to physical gold (“Gold ETPs”). The value of commodities, such as gold, typically is based upon the price movements of the physical commodity or an economic variable linked to such price movements. Price movements in gold, gold futures contracts, and Gold ETPs may fluctuate quickly and dramatically. Some factors that impact the price of gold, gold futures contracts, and Gold ETPs include, but are not limited to, overall market movements, changes in interest rates, changes in the global supply and demand for gold, the quantity of gold imports and exports, factors that impact gold production, such as drought, floods and weather conditions, technological advances in the processing and mining of gold, an increase in the hedging of precious metals, such as gold, and changes in economic and/or political conditions, including regulatory developments.

The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

The Fund may invest in underlying funds that invest in the securities of mid-capitalization companies. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole. Mid-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings. ◦Small-Capitalization Investing Risk.

| Prospectus [Line Items] | |
| Risk [Text Block] | Models and Data Risk. The composition of the Fund is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”).

| The Brinsmere Fund - Conservative ETF | Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Options Risk. The Fund may invest in underlying funds that utilize options strategies. Purchasing and selling (writing) options are a speculative activities and entail greater than ordinary investment risks. Options enable an underlying fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the underlying fund. The underlying fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the adviser to the underlying fund fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. An underlying fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the underlying fund writes the option and the date on which the underlying fund purchases an offsetting position or exits the option. |

| The Brinsmere Fund - Conservative ETF | REIT Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Investment Risk. The Fund may invest in underlying funds that invest primarily in REITs. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income. |
| The Brinsmere Fund - Conservative ETF | Specialty Credit Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Specialty Credit Risk. The Fund may invest in underlying funds that have exposure to specialty credit, a subset of the private credit market. Specialty credit refers to the private credit market that extends beyond traditional corporate lending. Specialty credit loans are secured by specific, tangible or financial collateral as opposed to a borrower’s overall corporate earnings. Investments in specialty credit are not traded in public markets, are illiquid, can be subject to various restrictions on resale, and there can be no assurance that an underlying fund will be able to realize the value of such investments in a timely manner. Additionally, specialty credit investments can range in credit quality depending on security-specific factors, including total leverage, amount of leverage senior to the security in question, variability in the issuer’s cash flows, the size of the issuer, the quality of assets securing debt and the degree to which such assets cover the subject company’s debt obligations. The companies in which an underlying fund invests directly or indirectly may be leveraged, often as a result of leveraged buyouts or other recapitalization transactions, and often will not be rated by national credit rating agencies. |
| The Brinsmere Fund - Conservative ETF | Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tax Risk. The contribution of the initial assets of the Fund was structured as a transaction in which no gain or loss was intended to be recognized for U.S. federal income tax purposes, however, there are no assurances that the IRS will agree that such contribution qualifies for nonrecognition. If the contribution did not qualify as a nonrecognition transaction for U.S. federal income tax purposes, such treatment could affect the Fund’s ability to qualify as a RIC under the Code, and affect whether gains and losses recognized by the Fund are treated as ordinary income or capital gain and potentially cause the Fund to be subject to income or excise taxes for under distributions. In turn, such treatment may also affect the amount, timing or character of income distributed to you by the Fund such that the Fund may be required to reclassify distributions previously distributed to you. |
