The tables below illustrate the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts in Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in Virtus Funds. More information on these and other discounts is available: (i) from your financial professional or other financial intermediary; (ii) under “Sales Charges” on page 74 of the fund’s prospectus; (iii) with respect to purchase of shares through specific intermediaries, in Appendix A to the fund’s prospectus, entitled “Intermediary Sales Charge Discounts and Waivers;” and (iv) under “Alternative Purchase Arrangements” on page 113 of the fund’s SAI.

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 fund 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. During the most recent fiscal year, the fund’s portfolio turnover rate was 27% of the average value of its portfolio.

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 mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies that are represented in one or more of the S&P Global Water Index, the NASDAQ OMX US Water or Global Water Indices, or the S-Network Global Water Index (Composite), or that are substantially engaged in water-related activities. Water-related activities consist of those that relate to the quality or availability of or demand for potable and non-potable water and include, but are not limited to, the following: water production, storage, transport and distribution; water supply enhancing or water demand-reducing technologies and materials; water planning, control and research; water conditioning, such as filtering, desalination, disinfection and purification; sewage and liquid waste treatment; and water delivery-related equipment and technology, consulting or engineering services relating to any of the above-mentioned activities. The specific activities that the fund may from time to time consider to qualify as “water-related activities” will change as markets, technologies and investment practices develop. The portfolio managers intend to diversify the fund’s investments across geographic regions. Under normal market conditions, the fund will typically invest (i) between 45%-75% of its total assets in U.S. securities, (ii) between 20%-45% of its total assets in European securities, and (iii) up to 25% of its total assets in Asia and other geographies. The fund may invest in emerging market securities.

The portfolio managers select investments on a bottom-up basis irrespective of market capitalization, geography, industry/sector or growth- or value-orientation, and may look for several of the following characteristics: higher than average sustainable growth; substantial capacity for growth of revenue and earnings; superior management; alignment to select United Nations Sustainable Development Goals (SDG’s) and other comparable societal goals; strong commitment to research and product development; and differentiated or superior product offerings addressing the structural demand drivers. The portfolio managers consider the level of active contribution to the improvement of water resource management during the stock selection process.

Companies’ Environmental, Social and Corporate Governance (“ESG”) practices are also considered as the portfolio managers believe this enhances the investment process.

The fund is “non-diversified,” which means that it may invest a significant portion of its assets in a relatively small number of issuers, which may increase risk. In addition to common stocks and other equity securities (such as preferred stocks and warrants), the fund may invest in securities issued in initial public offerings (IPOs), and may utilize foreign currency exchange contracts, options, and other derivative instruments. Although the fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below (in alphabetical order after the first seven risks).

> Market Volatility Risk. The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g. Russia’s invasion of Ukraine), acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.

> Issuer Risk. The fund will be affected by factors specific to the issuers of securities and other instruments in which the fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers.

> Equity Securities Risk. The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.

> Water-Related Risk. Because the fund focuses its investments in water-related companies, it is particularly affected by events or factors relating to this sector, which may increase risk and volatility.

> Focused Investment Risk. To the extent the fund focuses its investments on a limited number of issuers, sectors, industries or geographic regions, it may be subject to increased risk and volatility.

> Foreign Investing Risk. Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.

> ESG Risk. The fund’s consideration of ESG factors could cause the fund to perform differently from other funds. While the subadviser believes that the integration of ESG factors into the fund’s investment process has the potential to contribute to performance, ESG factors may not be considered for every investment decision and there is no guarantee that the integration of ESG factors will result in better performance.

> Counterparty Risk. A counterparty to a derivatives contract, repurchase agreement, a loan of portfolio securities or an unsettled transaction may be unable or unwilling to make timely settlement payments or otherwise honor its obligations to the fund.

> Credit Risk. If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline.

> Currency Rate Risk. Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund’s shares.

> Derivatives Risk. Derivatives may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.

> Emerging Markets Risk. Foreign investing risk may be particularly high to the extent that the fund invests in emerging market securities. Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.

> IPO Risk. Securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility.

> Leverage Risk. When a fund leverages its portfolio by borrowing or certain types of transactions or instruments, including derivatives, fund may be less liquid, may liquidate positions at an unfavorable time, and the volatility of the fund’s value may increase.

> Liquidity Risk. Certain securities may be substantially less liquid than many other securities, such as U.S. Government securities or common stocks. To the extent the fund invests in less liquid securities or the level of liquidity in a particular market is constrained, the lack of an active market for investments may cause delay in disposition or force a sale below fair value.

> Non-Diversification Risk. The fund is not diversified and may be more susceptible to factors negatively impacting its holdings to the extent the fund invests more of its assets in the securities of fewer issuers than would a diversified fund.

> Redemption Risk. One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken.

> Small and Medium Market Capitalization Risk. The fund’s investments in small and medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.

Please see “More Information About Risks Related to Principal Investment Strategies” in the fund’s prospectus for a more detailed description of the fund’s risks.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The bar chart and table below provide some indication of the potential risks of investing in the fund. The fund’s past performance, before and after taxes, is not necessarily an indication of how the fund will perform in the future. The current subadviser commenced providing services for the fund in July 2022 and therefore the returns shown in the table for periods prior to that date reflect the performance of other investment professionals.

The bar chart shows changes in the fund’s performance from year to year over a 10-year period. The table shows how the fund’s average annual returns compare to those of a broad-based securities market index and a more narrowly based index that reflects the market sectors in which the fund invests.

The fund’s investment adviser has contractually agreed to limit the fund’s total operating expenses (excluding certain expenses, such as taxes, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, expenses incurred in connection with any merger or reorganization, unusual or infrequently occurring expenses (such as litigation), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 1.22% for Class A Shares, 1.97% for Class C Shares, 0.93% for Institutional Class Shares, 0.94% for Class P Shares and through February 1, 2024. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed and/or fees waived under these arrangements for a period of three years following the date such waiver or reimbursement occurred, provided that the recapture does not cause the fund to exceed its expense limit in effect at the time of the waiver or reimbursement, and any in effect at the time of recapture, after repayment is taken into account.

The deferred sales charge is imposed on Class C Shares redeemed during the first year only.
