| China A-Shares Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | China A-Shares Risk. A-Shares are issued by companies incorporated in mainland China and are denominated in Chinese renminbi and traded on the two main Chinese exchanges: the Shanghai Stock Exchange (“SSE”) and Shenzhen Stock Exchange (“SZSE”). Foreign investors can access investments in A-Shares by obtaining a Qualified Foreign Institutional Investor (“QFII”) or a Renminbi Qualified Foreign Institutional Investor (“RQFII”) license, as well as through the Stock Connect Program, which is a securities trading and clearing program with an aim to achieve mutual stock market access between the China and Hong Kong markets. Stock Connect was developed by Hong Kong Exchanges and Clearing Limited, the SSE (in the case of Shanghai Connect) or the SZSE (in the case of Shenzhen Connect), and the China Securities Depository and Clearing Corporation Limited (“CSDCC”). The Fund currently intends to gain exposure to A-Shares through the Stock Connect Programs. The markets on which A-Shares trade are considered emerging markets characterized by generally low trading volume and less market liquidity due to various factors. For example, investments in A-Shares are subject to various regulations and limits, and the recoupment or repatriation of assets invested in A-Shares is subject to restrictions imposed by the Chinese government. In addition, investors from outside mainland China may face difficulties or prohibitions accessing certain A-Shares that are part of a restricted list in countries such as the U.S. A-Shares may also be subject to frequent and widespread trading halts, which can increase pricing volatility and cause the A-Shares to become illiquid. Trading suspensions in certain stock could lead to greater market execution, clearing and settlement risks and costs for the Fund, and the creation and redemption of Creation Units (as defined below) may also be disrupted. These risks, among others, could adversely affect the value of the Fund’s investments. |
| Concentration Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Concentration Risk. The Fund’s investments will be concentrated in a particular industry or group of related industries to the extent that the Index is so concentrated. In such event, the value of the Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. ◦Machinery Industry Risk. Companies in the machinery industry may be subject to risks associated with cyclical demand, high capital intensity, and technological obsolescence. These companies face challenges from fluctuating commodity and energy costs, supply chain disruptions, and the availability of skilled labor. Rapid advances in technology and customer demand for automation, efficiency, and sustainability require continuous investment in research and development, which may not always generate successful products or adequate returns.

| Risk [Text Block] | Machinery Industry Risk. Companies in the machinery industry may be subject to risks associated with cyclical demand, high capital intensity, and technological obsolescence. These companies face challenges from fluctuating commodity and energy costs, supply chain disruptions, and the availability of skilled labor. Rapid advances in technology and customer demand for automation, efficiency, and sustainability require continuous investment in research and development, which may not always generate successful products or adequate returns. |
| Currency Exchange Rate Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Exchange Rate Risk. The Fund may invest in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. |
| Depositary Receipt Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares. |
| Emerging Markets Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. The Fund may 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 global trade policy as well as 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. ◦Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value.

| Emerging Markets Risk, Capital Controls And Sanctions Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value. |
| Equity Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. The equity securities held in the Fund’s portfolio 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, regional armed conflict, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the 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. |
| ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | TF 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 Authorized Participants (“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. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ◦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. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, 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.

| 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 Authorized Participants (“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. |
| ETF Risks, Cash Redemption Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. |
| 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. |
| 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.

| Risk [Text Block] | Trading. Although Shares are listed for trading on Cboe BZX Exchange, 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. |
| Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations, the imposition of tariffs, or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Investments in non-U.S. 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. |
| Geographic Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Investment Risk. The Fund invests a significant portion of its assets in the securities of companies in a single country and, as a result, it is more likely to be impacted by events or conditions affecting that country. ◦China and Hong Kong-Specific Risk. Investments in Chinese issuers subject the Fund to risks specific to China. Investments in the securities of Chinese issuers that trade on an exchange in Hong Kong subject the Fund to risks specific to China and Hong Kong. China and Hong Kong may be subject to considerable degrees of economic, political and social instability. China and Hong Kong are developing markets and demonstrate significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and is expanding the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. China is also vulnerable economically to the impact of a public health crisis, which could depress consumer demand, reduce economic output, and potentially lead to market closures, travel restrictions, and quarantines, all of which would negatively impact China’s economy and could affect the economies of its trading partners. Further, any attempt by China to tighten its control over Hong Kong’s political, economic, legal or social policies may result in an adverse effect on Hong Kong’s markets For purposes of raising capital offshore on exchanges outside of China, including on U.S. exchanges, many Chinese-based operating companies are structured as Variable Interest Entities (“VIEs”). In this structure, the Chinese-based operating company is the VIE and establishes a shell company in a foreign jurisdiction, such as the Cayman Islands. The shell company lists on a foreign exchange and enters into contractual arrangements with the VIE. This structure allows Chinese companies in which the government restricts foreign ownership to raise capital from foreign investors. While the shell company has no equity ownership of the VIE, these contractual arrangements permit the shell company to consolidate the VIE’s financial statements with its own for accounting purposes and provide for economic exposure to the performance of the underlying Chinese operating company. Therefore, an investor in the listed shell company, such as the Fund, will have exposure to the Chinese-based operating company only through contractual arrangements and has no ownership in the Chinese-based operating company. Furthermore, because the shell company only has specific rights provided for in these service agreements with the VIE, its abilities to control the activities at the Chinese-based operating company are limited and the operating company may engage in activities that negatively impact investment value. ◦Investments in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. While the Japanese economy has recently emerged from a prolonged economic downturn, Japan’s economic growth rate may remain relatively low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanoes, typhoons and tsunamis. Additionally, decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosure rates may have an adverse impact on the economy of Japan. Japan also has few natural resources, and any fluctuation or shortage in the commodity markets could have a negative impact on Japanese securities.

| Geopolitical Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments. |
| Index Methodology Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Methodology Risk. The Index may not include all Robotics Actuator Companies because the Index includes only those companies meeting the Index criteria. For example, Robotics Actuator Companies that would otherwise be included in the Index might be excluded from the Index if they are limited partnerships or do not otherwise meet the Index’s screening criteria based on free-float, market capitalization, or trading volume. |
| Index Provider Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Provider Risk. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Adviser relies upon the Index Provider and its agents to compile, determine, maintain, construct, reconstitute, rebalance, compose, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders. |
| IPO Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | IPO Risk. The Fund may invest in securities offered in an IPO or in companies that have recently completed an IPO. IPO shares are often subject to extreme price volatility and speculative trading due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer’s business model, quality of management, earnings growth potential, and other criteria used to evaluate its investment prospects. Such stocks may have exhibited price appreciation in connection with the IPO that is not sustained, and it is not uncommon for stocks to decline in value in the period following the IPO. The purchase of IPO shares may involve high transaction costs, and the Fund may lose money on an investment in such securities. In addition, IPOs share similar illiquidity risks of private equity and venture capital. |
| Issuer-Specific Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer-Specific Risk. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund. |
| Market Capitalization Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Capitalization Risk. ◦Large-Capitalization Investing. 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. 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. ◦Small-Capitalization Investing Risk. The Fund may 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.

| New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision. |
| Passive Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Passive Investment Risk. The Fund is not actively managed, and its sub-adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution or rebalancing of the Index in accordance with the Index methodology. |
| Robotics Actuator Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Robotics Actuator Companies Risk. Robotics Actuator Companies operate in rapidly evolving markets dependent on the adoption of robotics technologies, which may not develop as expected. Their performance is sensitive to capital spending cycles in industrial end markets, making them vulnerable to economic downturns. Robotics Actuator Companies also rely on complex global supply chains, which may be disrupted by shortages, geopolitical events, or cost increases. Robotics Actuator Companies face risks related to technological change, competition, product defects, system failures, and cybersecurity. They may also be subject to future regulatory, safety, and product liability risks. |
| Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.◦Industrials Sector Risk. The industrials sector can be significantly affected by, among other things, worldwide economic growth, supply and demand for specific products and services, rapid technological developments, international political and economic developments, environmental issues, tariffs and trade barriers, and tax and governmental regulatory policies. As the demand for, or prices of, industrials increase, the value of the Fund’s investments generally would be expected to also increase. Conversely, declines in the demand for, or prices of, industrials generally would be expected to contribute to declines in the value of such securities. Such declines may occur quickly and without warning and may negatively impact the value of the Fund and your investment. |

Such declines may occur quickly and without warning and may negatively impact the value of the Fund and your investment. |
| SPAC-Derived Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | SPAC-Derived Companies Risk. The Fund may invest in companies that are derived from a SPAC. These companies may be unseasoned and lack a trading history, a track record of reporting to investors, and widely available research coverage. SPAC-derived companies are thus often subject to extreme price volatility and speculative trading. These stocks may have above-average price appreciation in connection with a potential business combination with a SPAC prior to inclusion in the Index. The price of stocks of SPAC-derived companies included in the Index may not continue to appreciate and the performance of these stocks may not replicate the performance exhibited in the past. In addition, SPAC-derived companies may share similar illiquidity risks of private equity and venture capital. The free float shares held by the public in a SPAC-derived company are typically a small percentage of the market capitalization. The ownership of many SPAC-derived companies often includes large holdings by venture capital and private equity investors who seek to sell their shares in the public market in the months following a business combination transaction when shares restricted by lock-up are released, causing greater volatility and possible downward pressure during the time that locked-up shares are released. |
| Tracking Error Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index. |
| 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. |
| Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). |
