| Risk [Text Block] | Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. These changes in value may result from factors affecting individual issuers, industries or the stock market as a whole. In addition, equity markets tend to be cyclical which may cause stock prices to fall over short or extended periods of time.

| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Large-Cap Securities Risk. Stocks of large companies as a group can fall out of favor with the market, causing the Fund to underperform investments that have a greater focus on mid-cap or small-cap stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
|
||||||||||||
| Zacks Earnings Consistent Portfolio ETF | Management Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio.

| Risk [Text Block] | Small and Medium Cap Securities Risk. The earnings and prospects of small and medium sized companies are more volatile than larger companies and may experience higher failure rates than larger companies. Mid- and small-capitalization companies typically have more limited product lines, markets and financial resources than larger companies, and their securities may trade less frequently and in more limited volume than those of larger, more mature companies.
|
||||||||||||
| Zacks Earnings Consistent Portfolio ETF | Common Stock Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Common Stock Risk. Investments in shares of common stock may fluctuate in value in response to many factors. Such price fluctuations subject the Fund to potential losses.
|
||||||||||||
| Zacks Earnings Consistent Portfolio ETF | New Advisor Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | New Advisor Risk. The Advisor has only recently begun serving as an investment advisor to ETFs. As a result, investors do not have a long-term track record of managing an ETF from which to judge the Advisor, and the Advisor may not achieve the intended result in managing the Fund.
|
||||||||||||
| Zacks Earnings Consistent Portfolio ETF | Market Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Market Risk. Market risk refers to the possibility that the value of securities held by the Fund may decline due to daily fluctuations in the market. Market prices for securities change daily as a result of many factors, including developments affecting the condition of both individual companies and the market in general. The price of a security may even be affected by factors unrelated to the value or condition of its issuer, including changes in interest rates, economic and political conditions, and general market conditions. The Fund’s performance per Share will change daily in response to such factors.
|

| Zacks Earnings Consistent Portfolio ETF | Early Closetrading Halt Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may prevent the Fund from buying or selling certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.
|
||||||||||||
| Zacks Earnings Consistent Portfolio ETF | Etf Structure Risks [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | ETF Structure Risks. Each Fund is structured as an ETF and as a result is subject to the special risks, including:
that Shares will continue to meet the listing requirements of an Exchange. If a Fund’s Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.
|

| Zacks Earnings Consistent Portfolio ETF | Investment Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Investment Risk. Various sectors of the global financial markets have been experiencing an extended period of adverse conditions. Market uncertainty has increased dramatically, particularly in the United States and Europe, and adverse market conditions have expanded to other markets. These conditions have resulted in disruption of markets, periods of reduced liquidity, greater volatility, general volatility of spreads, an acute contraction in the availability of credit and a lack of price transparency. The long-term impact of these events is uncertain but could continue to have a material effect on general economic conditions, consumer and business confidence, and market liquidity.

| Zacks Earnings Consistent Portfolio ETF | Cybersecurity Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Cybersecurity Risk. As part of its business, the Advisor processes, stores, and transmits large amounts of electronic information, including information relating to the transactions of the Fund. The Advisor and the Fund are therefore susceptible to cybersecurity risk. Cybersecurity failures or breaches of the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, and/or reputational damage. The Fund and its shareholders could be negatively impacted as a result.
|
||||||||||||
| Zacks Earnings Consistent Portfolio ETF | Market Disruption And Geopolitical Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Market Disruption and Geopolitical Risk. U.S. market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including Russia’s military invasion of Ukraine and the conflicts in the Middle East), geopolitical developments (including trading and tariff arrangements, and sanctions), instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally). |

| Zacks Focus Growth ETF | Growth Stock Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Growth Stock Risk. Growth stocks may underperform value stocks and stocks in other broad style categories (and the stock market as a whole) over any period and may shift in and out of favor with investors generally, sometimes rapidly, depending on changes in market, economic, and other factors. Growth stocks may be more volatile than other stocks because they are generally more sensitive to investor perceptions of the issuing company’s growth of earnings potential. Investments in growth stocks present the risk that the Advisor’s perceptions of the company’s growth potential are wrong.
|
||||||||||||
| Zacks Focus Growth ETF | Concentration Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Concentration Risk. As a non-diversified fund, the Fund may be subject to greater volatility than a more diversified investment. A fluctuation in one stock could significantly affect overall performance. The Fund is also concentrated in fewer sectors than its benchmarks, and its performance may suffer if these sectors underperform the overall stock market.

| Risk [Text Block] | Small and Medium Cap Securities Risk. The earnings and prospects of small and medium sized companies are more volatile than larger companies and may experience higher failure rates than larger companies. Small and medium sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures and may have limited markets, product lines, or financial resources and lack management experience.

| Zacks Small/Mid Cap ETF | Fund Investing Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Fund Investing Risk. Investments in other investment companies subject the Fund to additional operating and management fees and expenses. Investors in the Fund will indirectly bear fees and expenses charged by the funds in which the Fund invests, in addition to the Fund’s direct fees and expenses. The Fund’s performance depends in part upon the performance of the investment advisor to each Underlying Fund, the strategies and instruments used by the Underlying Funds, and the Advisor’s ability to select Underlying Funds and effectively allocate fund assets among them.
|
||||||||||||
| Zacks Small/Mid Cap ETF | Etf Investing Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | ETF Investing Risk. The Fund’s investment in ETFs may subject the Fund to additional risks than if the Fund would have invested directly in the ETF’s underlying securities. These risks include the possibility that an ETF may experience a lack of liquidity that can result in greater volatility than its underlying securities, an ETF may trade at a premium or discount to its net asset value, or an ETF may not replicate exactly the performance of the benchmark index it seeks to track. In addition, investing in an ETF may also be costlier than if the Fund had owned the underlying securities directly. The Fund and, indirectly, shareholders of the Fund, bear a proportionate share of the ETF’s expenses, which include management and advisory fees and other expenses. In addition, the Fund will pay brokerage commissions in connection with the purchase and sale of the ETFs in its portfolio.
|
||||||||||||
| Zacks Small/Mid Cap ETF | Control Of Underlying Funds Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Control of Underlying Funds Risk. The Underlying Funds each have their own unique investment objective, strategies, and risks. There is no guarantee that the Underlying Funds will achieve their investment objectives and the Fund has exposure to the investment risks of the Underlying Funds in direct proportion to the allocation of assets among the funds. The investment policies of the Underlying Funds may differ from the Fund’s policies.
Although the Fund and the Advisor will evaluate regularly each Underlying Fund to determine whether its investment program is consistent with the Fund’s investment objective, the Advisor will not have any control over the investments made by an Underlying Fund. Even though each Underlying Fund is subject to certain constraints, the investment advisor of each Underlying Fund may change aspects of its investment strategies at any time. The Advisor will not have the ability to control or otherwise influence the composition of the investment portfolio of an Underlying Fund.
|
||||||||||||
| Zacks Small/Mid Cap ETF | Cash And Cash Equivalents Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Cash and Cash Equivalents Risk. At any time, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time.
|
||||||||||||
| Zacks Small/Mid Cap ETF | U S Government Securities Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | U.S. Government Securities Risk. U.S. government securities risk refers to the risk that debt securities issued or guaranteed by certain U.S. Government agencies, instrumentalities, and sponsored enterprises are not supported by the full faith and credit of the U.S. Government, and so investments in their securities or obligations issued by them involve credit risk greater than investments in other types of U.S. Government securities.

| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Portfolio Turnover Risk. The portfolio manager will sell Underlying Funds and other securities when it is in the best interest of the Fund and its shareholders to do so without regard to the length of time they have been held. As portfolio turnover may involve paying brokerage commissions and other transaction costs, there could be additional expenses for the Fund. High rates of portfolio turnover may also result in the realization of short-term capital gains and losses. Any distributions resulting from such gains will be considered ordinary income for federal income tax purposes.

Market prices for securities change daily as a result of many factors, including developments affecting the condition of both individual companies and the market in general. The price of a security may even be affected by factors unrelated to the value or condition of its issuer, including changes in interest rates, economic and political conditions, and general market conditions. The Fund’s performance per share will change daily in response to such factors.

Foreign securities include ADRs. Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply.

The long-term impact of these events is uncertain but could continue to have a material effect on general economic conditions, consumer and business confidence, and market liquidity.

| Risk [Text Block] | Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Advisor, and/or other service providers (including custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality. In an extreme case, a shareholder’s ability to exchange or redeem Fund shares may be affected. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of those securities could decline if the issuers experience cybersecurity incidents.

| Risk [Text Block] | Market Disruption and Geopolitical Risk. U.S. market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including Russia’s military invasion of Ukraine and the conflicts in the Middle East), geopolitical developments (including trading and tariff arrangements, and sanctions), instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally). |

| Risk [Text Block] | Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests.

| Zacks Dividend Fund | Foreign Investment Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. Changes in exchange rates and interest rates, and the imposition of sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and/or other governments may adversely affect the values of the Fund’s foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs. Unsponsored ADRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Value-Oriented Investment Strategies Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments or other factors. Value investing is subject to the risk that the market will not recognize a security’s inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.

| Zacks Dividend Fund | Lending Portfolio Securities Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Lending Portfolio Securities Risk. The Fund may lend its portfolio securities to broker-dealers and banks, provided that it may not lend securities if, as a result, the aggregate value of all securities loaned would exceed 33 1/3% of its total assets. The collateral, including the investment of any cash collateral, is subject to market depreciation. In the event of bankruptcy or other default of the borrower, the Fund could experience delays in both liquidating the loan collateral and recovering the loaned securities and losses. The collateral (including any investment of cash collateral) is not subject to the percentage limitations on the Fund’s investments described elsewhere in this prospectus.

| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Market Capitalization Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion. The securities of small-capitalization and mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

| Zacks Dividend Fund | Sector Focus Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds and, thus, will be more susceptible to negative events affecting those sectors. For example, as of November 30, 2025, 22.2% of the Fund’s assets were invested in the financials sector. The performance of companies in the financial sector may be adversely impacted by many factors, including, among others: government regulations of, or related to, the sector; governmental monetary and fiscal policies; economic, business or political conditions; credit rating downgrades; changes in interest rates; price competition; and decreased liquidity in credit markets. The financial sector has experienced significant losses and a high degree of volatility in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

| Zacks Dividend Fund | Preferred Stock Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Preferred Stock Risk. Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. The market value of preferred stock is subject to company-specific and market risks applicable generally to equity securities and is also sensitive to changes in the company’s creditworthiness, the ability of the company to make payments on the preferred stock, and changes in interest rates, typically declining in value if interest rates rise.

| Zacks Dividend Fund | Etf Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | ETF Risk. Investing in an ETF will provide the Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values (“NAVs”). In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

| Zacks Dividend Fund | Warrants And Rights Risk [Member] | |||||||||||||
| Prospectus [Line Items] | |||||||||||||
| Risk [Text Block] | Warrants and Rights Risk. Warrants and rights may lack a liquid secondary market for resale. The prices of warrants and rights may fluctuate as a result of speculation or other factors. Warrants and rights can provide a greater potential for profit or loss than an equivalent investment in the underlying security. Prices of warrants and rights do not necessarily move in tandem with the prices of their underlying securities and therefore, are highly volatile and speculative investments. If a warrant or right expires without being exercised, the Fund will lose any amount paid for the warrant or right.
