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. Because the Fund is newly organized, portfolio turnover information is not yet available.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. 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.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is an actively managed exchange-traded fund (“ETF”) whose portfolio is constructed with the aim of delivering positive returns, before any fees and expenses, when the 2-year interest rate (the “2-Year Rate”) rises. The Fund is expected to experience losses when the 2-Year Rate falls. The 2-Year Rate is a broad measure of the cost of borrowing cash overnight collateralized by Treasury securities compounded over a period of two years. To achieve its investment objective of hedging against increases in the 2-Year Rate, the Fund invests in various derivatives (including futures, options, interest rate swaps, and swaptions). The Fund may take long positions in interest rate swaps to seek to benefit from rising interest rates. The Fund may also invest in ETFs that invest in U.S. Treasury bills or option contracts linked to ETFs that primarily invest in U.S. Treasury securities to implement the Fund’s hedging strategy. The Fund invests in U.S. Treasury bills as collateral for the Fund’s derivatives transactions.
In addition, the Fund will take long or short positions in interest rate payer or receiver swaptions to limit losses and gains. By taking these positions to limit losses, the upside cap (described below) is a by-product of seeking to limit the downside losses. For example, the Fund will take a long position in receiver swaptions to reduce the Fund’s exposure to declines in the 2-Year Rate, which is expected to have the effect of offsetting losses resulting from a decrease in the 2-Year Rate such that there is a hedge against the 2-Year Rate declining below a specific percentage over a calendar quarter (“floor”). Additionally, the Fund takes a short position in (sells) payer swaptions to offset the costs associated with the purchased receiver swaption and foregoes the potential upside from increases in the 2-Year Rate above a capped level over the same period (“upside cap”). As a result, some upside potential may be foregone from rising interest rates in certain market environments. The Fund generally intends to hold swaptions maturing in three months for the purpose of seeking to provide more predictable returns in a market cycle during the applicable hedge period. The Fund will generally seek to limit losses to a maximum loss of 20%, before fees and expenses, over a calendar quarterly period, with the potential upside capped between 5% to 35%, before fees and expenses, over the calendar quarter. The upside cap could be more or less depending on market conditions. There can be no assurance that the Fund will be successful in limiting losses.
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.

Vest 2 Year Interest Rate Hedge ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock 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.
Vest 2 Year Interest Rate Hedge ETF | Associated Risks Of Derivative Instruments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Associated Risks of Derivative Instruments. The Fund invests in instruments that derive their performance from the performance of an underlying reference interest rate or instrument. Derivatives, such as those in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, or are not correlated with the performance of their underlying interest rate or instrument or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid.
Vest 2 Year Interest Rate Hedge ETF | Associated Risks Of Derivative Instruments Risk, Futures Contracts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Futures Contracts Risk. 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.
Vest 2 Year Interest Rate Hedge ETF | Associated Risks Of Derivative Instruments Risk, Interest Rate Swaps Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Interest Rate Swaps Risk. In an interest rate swap, the Fund and another party exchange their rights to receive interest payments based on a reference interest rate. Because interest rate movements do not always align with projections of a swap counterparty, interest rate swaps are subject to interest rate risk. An interest rate swap may fail to perform as intended and may not offset adverse changes in interest rates fully or at all. An interest rate swap may also reduce the Fund’s gains due to favorable changes in interest rates and result in losses to the Fund.
Vest 2 Year Interest Rate Hedge ETF | Associated Risks Of Derivative Instruments Risk, Options Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Options Risk. Purchasing and writing options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of derivatives, such as options, can lead to losses because of adverse movements in the price or value of the underlying reference rate or asset, which may be magnified by certain features of the options. These risks are heightened when the Fund’s portfolio managers use options to enhance the Fund’s return or as a substitute for a position or security. When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference rate or asset is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value of the reference rate or asset subject to the option, an increase in interest rates, a change in the actual and perceived volatility of the market and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the underlying reference rate or asset. The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the underlying reference rate or asset.
Vest 2 Year Interest Rate Hedge ETF | Associated Risks Of Derivative Instruments Risk, Swaps Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Swaps Risk. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter (“OTC”) market, which generally has less transparency than exchange-traded derivatives instruments. Swaps involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a swap due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the swap in a bankruptcy or other reorganization proceeding.
Vest 2 Year Interest Rate Hedge ETF | Associated Risks Of Derivative Instruments Risk, Swaptions Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Swaptions Risk. A swaption is an option contract that gives the holder the right (but not the obligation) to enter into a swap at a predetermined rate at expiration in exchange for a premium payment. Swaptions enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of swaptions can be volatile, and a small investment in swaptions can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing swaptions. Additionally, the value of the option may be lost if the Fund fails to exercise such option at or prior to its expiration. When the Fund writes (sells) a swaption, there is a risk that the option will be exercised by the purchaser when the market value of the underlying interest rate swap changes unfavorably with respect to the Fund. The Fund’s loss may exceed the option premium received by the Fund.
Vest 2 Year Interest Rate Hedge ETF | Capped Upside Return Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Capped Upside Return Risk. To the extent that the Fund uses a derivatives instrument to cap the Fund’s return when the 2-Year Rate increases above a specified level at the end of the calendar quarter, the Fund will not participate in gains beyond the cap. In the event an investor purchases shares after the date on which the Fund enters into such derivative instruments (i.e., at the end of each calendar quarter) and the 2-Year Rate has risen to a level near to the cap, there may be little or no ability for that investor to experience an investment gain on their shares with respect to the 2-Year Rate during that quarter.
Vest 2 Year Interest Rate Hedge ETF | Cash Redemption Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments in order 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. Purchases and redemptions of creation baskets with cash may cause the Fund to incur certain transaction costs, such as brokerage commissions, that it would otherwise avoid if the Fund had conducted creation unit transactions on an in-kind basis.
Vest 2 Year Interest Rate Hedge ETF | Commodity Pool Regulatory Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Commodity Pool Regulatory Risk. The Fund’s investment exposure to futures instruments and interest rate swaps will cause it to be deemed to be a commodity pool, thereby subjecting the Fund to regulation under the Commodity Exchange Act (“CEA”) and CFTC rules. The Adviser is registered as a Commodity Pool Operator (“CPO”), and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO imposes additional compliance obligations on the Adviser and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s registration as a CPO are not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.
Vest 2 Year Interest Rate Hedge ETF | Counterparty Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Counterparty Risk. The risk of loss to the Fund for derivative transactions (such as interest rate swaps or swaptions) that are entered into on a net basis depends on which party is obligated to pay the net amount to the other party. If the counterparty is obligated to pay the net amount to the Fund, the risk of loss to the Fund is loss of the entire amount that the Fund is entitled to receive. If the Fund is obligated to pay the net amount, the Fund’s risk of loss is generally limited to that net amount. If a derivative instrument involves the exchange of the entire principal value of a security, the entire principal value of that security is subject to the risk that the other party to the transaction will default on its contractual delivery obligations. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its investment objective.
Vest 2 Year Interest Rate Hedge ETF | ETF Risks Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock 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 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.
◦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 the 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. 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.

Vest 2 Year Interest Rate Hedge ETF | Floor Loss Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Floor Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to provide protection against declines below a floor in the 2-Year Rate over a calendar quarter. The Fund’s strategy seeks to hedge against increases in the 2-Year Rate, while limiting downside losses from a significant decrease in the 2-Year Rate, if shares are bought on the day on which the Fund enters into these derivatives and held until they expire at the end of the calendar quarter. In the event an investor purchases shares after the date on which the derivatives were entered into and the Fund has already increased in value, then the investor may experience losses prior to gaining the protection offered by the floor, which is not guaranteed. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including the loss of its entire investment.
Vest 2 Year Interest Rate Hedge ETF | Hedging Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Hedging Risk. Derivatives used by the Fund to hedge against increases in the 2-Year Rate may not perform as intended. There can be no assurance that the Fund’s hedging transactions will be effective.
Vest 2 Year Interest Rate Hedge ETF | Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets. The Fund’s exposure to derivatives tied to interest rates subjects the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. Investing in derivatives tied to interest rates is speculative and can be extremely volatile. There is no guarantee that the Fund will have positive performance even in environments of sharply rising interest rates.
Vest 2 Year Interest Rate Hedge ETF | Management Risk Member

Risk Narrative [Text Block] rr_RiskTextBlock 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.
Vest 2 Year Interest Rate Hedge ETF | Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Market Risk. The instruments 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 markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. 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.
Vest 2 Year Interest Rate Hedge ETF | New Fund Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock 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.
Vest 2 Year Interest Rate Hedge ETF | Other Investment Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other ETFs. 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. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds as the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies. Investments in ETFs are also subject to the “ETF Risks” described above.
Vest 2 Year Interest Rate Hedge ETF | Purchase And Sale Timing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Purchase and Sale Timing Risk. The Fund is designed to provide protection against declines below a floor in the 2-Year Rate over a calendar quarter and provide for participation in gains of the 2-Year Rate up to a specified cap each calendar quarter. Because the derivatives used by the Fund to protect against downside losses and cap upside returns will expire each calendar quarter, if you purchase or sell shares on a date other than the first day of the calendar quarter or if you hold shares for more or less than a calendar quarter, the value of your investment in shares may not be protected against the specified declines and may not participate fully in potential gains from 2-Year Rate increases.
Vest 2 Year Interest Rate Hedge ETF | Tax Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Tax Risk. The use of derivatives strategies, such as writing (selling) and purchasing options, involves complex rules that will determine for income tax purposes the amount, character and timing of recognition of the gains and losses the Fund realizes in connection therewith. The Fund expects to generate premiums from its sale of options. These premiums typically will result in short-term capital gains for federal income tax purposes. In addition, if positions held by the Fund are treated as “straddles” subject to the federal tax rules applicable to straddles under the Internal Revenue Code of 1986, as amended (the “Code”), or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury regulations, the Fund would be subject to certain rules that may affect the amount, character and timing of a Fund’s recognition of gains and losses with respect to straddle positions by requiring, among other things, that: (1) any loss realized on disposition of one position of a straddle may not be recognized to the extent that a Fund has unrealized gains with respect to the other position in such straddle; (2) a Fund’s holding period in straddle positions be suspended while the straddle exists (possibly resulting in a gain being treated as short-term capital gain rather than long-term capital gain); (3) the losses recognized with respect to certain straddle positions that are part of a mixed straddle and that are not subject to Section 1256 of the Code, be treated as 60% long-term and 40% short-term capital loss; (4) losses recognized with respect to certain straddle positions that would otherwise constitute short-term capital losses be treated as long-term capital losses; and (5) the deduction of interest and carrying charges attributable to certain straddle positions may be deferred.

Risk Narrative [Text Block] rr_RiskTextBlock U.S. Treasury Securities Risk. The Fund will invest in U.S. Treasury securities issued or guaranteed by the U.S. Treasury. U.S. government securities are subject to market risk, interest rate risk and counterparty risk. Securities, such as those issued or guaranteed the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund.
