| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover | |||||||||||||||||||||||
| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. This rate excludes the value of portfolio securities received or delivered as a result of in-kind creations or redemptions of the Fund’s Shares and securities, including options, whose maturities or expiration dates at the time of acquisition were one year or less. For the fiscal year ended August 31, 2024, the predecessor fund of the Fund portfolio turnover rate was 8% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then continue to hold or redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategy | |||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective principally by investing in a portfolio of the stocks included in the Nasdaq-100® Index (the “Nasdaq-100®” or the “Reference Index”) and a put spread options collar (i.e., a mix of written (sold) call options, long (bought) put options, and written (sold) put options) on the Nasdaq-100. The Fund seeks to generate tax efficient monthly income from a combination of the dividends received from the Fund’s equity holdings and the premiums earned from the put spread options collar. The put spread options collar seeks to generate a net-credit by receiving premium from the sale of the call and put options that is greater than the cost of buying the protective put options. The put spread options collar is designed to reduce the Fund’s volatility and provide a measure of downside protection, but upside gains will be limited.
The Nasdaq-100® is a market capitalization weighted index comprised of the securities of 100 of the largest non-financial companies listed on The Nasdaq Stock Market LLC based on their market capitalization. Such securities may include companies domiciled domestically or internationally (including in emerging markets), and may include common stocks, ordinary shares, depositary receipts representing interests in non-U.S. companies, and tracking stocks. As of August 31, 2024, the Nasdaq-100® had significant exposure to companies in the information technology sector. The Fund will concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Reference Index concentrates in an industry or group of industries.
The Fund will generally use a “replication” strategy to invest in the Nasdaq-100®, meaning the Fund will generally invest in all of the component securities of the Nasdaq-100® in the same approximate proportions as in the Nasdaq-100®. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Nasdaq-100® whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Nasdaq-100 as a whole, when NEOS Investment Management, LLC, the Fund’s investment adviser (the “Adviser”) believes it is in the best interests of the Fund (e.g., when replicating the Nasdaq-100® involves practical difficulties or substantial costs, a Nasdaq-100® constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Nasdaq-100®). The Fund rebalances the equity positions of its investment portfolio to correspond to the extent reasonably possible each time the Nasdaq-100® Index reconstitutes. The Nasdaq-100® reconstitutes annually and often reconstitutes quarterly. In some cases, there are special reconstitutions of the Nasdaq-100®.
The Adviser generally utilizes a proprietary, systematic rules-based model to manage the Fund’s options positions in an objective manner, which may signal the written call options should be closed prior to expiration to potentially capture gains and minimize losses due to the movement of the Nasdaq-100® (e.g., after an increase in the Nasdaq-100®, the model may indicate that the short call should be closed so the Fund can capture more upside potential in the reference asset, or the model may determine most of the premium derived from the sale of the call has been captured due to a falling market).
The Fund’s put spread options collar strategy typically consists of three components: (i) selling call options on the Nasdaq-100® or another reference asset representing U.S. equity securities on up to 100% of the value of the equity securities held by the Fund to generate premium from such options, while (ii) simultaneously reinvesting a portion of such premium to buy put options on the same reference asset(s) to “hedge” or mitigate the downside risk associated with owning equity securities and (iii) selling put options on the Nasdaq-100® to generate additional premium.
The options purchased or sold by the Fund will typically have an expiration date approximately 6 weeks from the time of purchase or sale. Options are rolled at the end of the month. The written calls and puts along with purchased puts for the new put spread collar are reset to current market levels. The Fund expects the total value of the call options and the total value of the put options to each be up to 100% of the Fund’s net assets. The Fund will use a portion of the premium received from writing call and put options to purchase put options. Call options written by the Fund will typically have a strike price that is at, near, or higher than the current price of the reference asset, and put options purchased by the Fund will typically have a strike price that is lower (in some cases, significantly lower) than the current price of the reference asset. Put options written will typically have a strike price that is lower than the long put option. In addition, both the call and put options will be traded on a national securities exchange and be settled in cash.
The Fund seeks tax efficient returns by utilizing index options that qualify as “Section 1256 Contracts.” If such options are held at year end, the Fund will receive favorable tax treatment on such investments. Under Internal Revenue Code rules, they will be deemed as if they were sold at fair market value on the last business day of the tax year. If the Section 1256 contracts produce capital gain or loss, such gain or loss on the Contracts open at the end of the year, or terminated during the year, will be treated as 60% long term and 40% short term, instead of 100% short term gains. The Fund may seek to take advantage of tax loss harvesting opportunities by taking investment losses from certain equity and/or options positions. This can be accomplished by taking investment losses from certain equity to offset realized and/or options positions to offset realized taxable gains of equities and/or options positions.
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. Additionally, the Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover.
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in securities, or derivative instruments linked to securities, of companies that are included in the Fund’s Reference Index. The remaining 20% may hold cash or cash items under certain market conditions.

| Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The Fund will commence operations and acquire the assets and liabilities of the Nationwide Nasdaq-100® Risk-Managed Income ETF, a series of the ETF Series Solutions (the “Predecessor Fund”), resulting from a reorganization of the Predecessor that took place on November 11, 2024. The Fund adopted the financial statements of the Predecessor Fund, the accounting successor of the Reorganization. Performance results shown in the bar chart and the performance table below reflect the performance of the Predecessor Fund. Note that while the investment strategy of the Fund and the Predecessor Fund both include an options strategy designed to reduce volatility and provide a measure of downside protection, the options strategy employed for the Fund has been modified.
The following performance information indicates some of the risks of investing in the Predecessor Fund. The bar chart shows the Predecessor Fund’s performance for the calendar year ended December 31. The table illustrates how the Predecessor Fund’s average annual returns for the 1-year and since inception periods compared with those of a broad measure of market performance as well as an additional index that represents the asset classes in which the Fund invests. The Predecessor Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information is also available on the Fund’s website at www.neosfunds.com.

The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.
