Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	These tables describe 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 if you and your family invest, or agree to invest in the future, at least $50,000 in Voya mutual funds. More information about these and other discounts is available from your financial intermediary and in the discussion in the Sales Charges section of the Prospectus (page 172), in Appendix A to the Prospectus, or the Purchase, Exchange, and Redemption of Shares section of the Statement of Additional Information (page 87). The Management Agreement provides for a “bundled fee” arrangement under which the Adviser provides (in addition to advisory services and administrative services), custodial, transfer agency, portfolio accounting, auditing and ordinary legal services in return for a single management fee. The Fund is responsible for applicable fees paid to financial intermediaries that maintain omnibus accounts and/or provide shareholder or participant record keeping services on behalf of their clients as well as any distribution or shareholder servicing plan payments, interest, taxes, investment-related costs, leverage expenses, and extraordinary expenses. In the future, the Fund will pay these fees to financial intermediaries that are affiliates of the Adviser, which will cause the Fund’s “Other Expenses” set forth in the fee table below to increase. As of the date of this Prospectus, it is not possible to estimate the amount of these fees.

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 mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance.During the most recent fiscal year, the Fund's portfolio turnover rate was 60% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example shows costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:11.16pt;font-weight:bold;text-transform:uppercase;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests primarily in a combination of underlying funds, which are actively managed funds or passively managed funds (index funds), including exchange-traded funds (collectively, “Underlying Funds”). The Underlying Funds may or may not be affiliated with the investment adviser. The Underlying Funds invest in U.S. stocks, international stocks, U.S. bonds, and other debt instruments and the Fund uses an asset allocation strategy designed for investors expecting to retire soon or are already retired. The Fund's current approximate target investment allocation (expressed as a percentage of its net assets) (“Target Allocation”) among the Underlying Funds is: 35% in equity securities and 65% in debt instruments. Although this is the Target Allocation, the actual allocation of the Fund's assets may deviate from the percentages shown.The allocation of the Fund’s assets between Underlying Funds affiliated with the investment adviser and Underlying Funds that are not affiliated with the investment adviser will vary over time, although the sub-adviser (“Sub-Adviser”) currently expects to invest, under normal circumstances, at least 10% of the Fund’s assets, and as much as 85%, in Underlying Funds affiliated with the investment adviser. When investing in Underlying Funds, the Sub-Adviser will typically consider environmental, social, and governance (“ESG”) factors as part of its investment analysis and decision-making processes for the Fund.The Target Allocation is measured with reference to the primary investment strategies of the Underlying Funds; actual exposure to equity securities and debt instruments will vary from the Target Allocation if an Underlying Fund is not substantially invested in accordance with its primary investment strategy. The Fund may periodically deviate from the Target Allocation based on an assessment of the current market conditions or other factors. Generally, the deviations fall within the range of +/- 10% relative to the current Target Allocation. The Sub-Adviser may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Fund, to achieve its investment objective, or to take advantage of particular opportunities.The Underlying Funds provide exposure to a wide range of traditional asset classes which include stocks, bonds, and cash and non-traditional asset classes (also known as alternative strategies) which include, but are not limited to, real estate, commodities, and floating rate loans.Equity securities in which the Underlying Funds invest include, but are not limited to, domestic and international large-, mid-, and small-capitalization stocks (may be growth oriented, value oriented, or a blend); emerging market securities; domestic and international real estate stocks, including real estate investment trusts (“REITs”); and natural resource/commodity securities.Debt instruments in which the Underlying Funds invest include, but are not limited to, domestic and international (including emerging markets) intermediate, long-term and short-term bonds; high-yield bonds commonly referred to as “junk bonds;”floating rate loans; and Treasury inflation protected securities.The Fund may invest in exchange-traded notes.The Fund may also invest in derivatives, including futures and swaps (including interest rate swaps, total return swaps, and credit default swaps), to make tactical asset allocations, as a substitute for taking a position in the underlying asset, to seek to minimize risk, and to assist in managing cash.The Fund will be rebalanced periodically to return to the Target Allocation. The Target Allocation may be changed at any time by the Sub-Adviser.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:11.16pt;font-weight:bold;text-transform:uppercase;">Principal Risks</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money on an investment in the Fund. There is no guarantee that the Fund will provide adequate income at and through your retirement or for any of your financial goals. The value of your investment in the Fund changes with the values of the Underlying Funds and their investments. The Fund is subject to the following principal risks (either directly or through investments in one or more Underlying Funds). Any of these risks, among others, could affect the Fund's or an Underlying Fund's performance or cause the Fund or an Underlying Fund to lose money or to underperform market averages of other funds. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk.Affiliated Underlying Funds: The manager’s selection of Underlying Funds presents conflicts of interest. The net management fee revenue received or costs incurred by the manager and its affiliates will vary depending on the Underlying Funds it selects for the Fund, and the manager will have an incentive to select the Underlying Funds (whether or not affiliated with the manager) that will result in the greatest net management fee revenue or lowest costs to the manager and its affiliates, even if that results in increased expenses and potentially less favorable investment performance for the Fund. The Fund invests in Class P3 shares of affiliated Underlying Funds for which the manager receives no management fees and bears all expenses incurred by or allocated to that class. As a result, investments in affiliated Underlying Funds will cause the manager to incur higher costs than would investments in unaffiliated Underlying Funds. Therefore, the manager may prefer to invest in an unaffiliated Underlying Fund. However, the manager may prefer to invest in an affiliated Underlying Fund over an unaffiliated Underlying Fund because the investment may be beneficial to the manager in managing the affiliated Underlying Fund by helping the affiliated Underlying Fund achieve economies of scale or by enhancing cash flows to the affiliated Underlying Fund. In certain circumstances, the manager would have an incentive to delay or decide against the sale of interests held by the Fund in affiliated Underlying Funds and may implement portfolio changes in a manner intended to minimize the disruptive effects and added costs of those changes to affiliated Underlying Funds. Although the Fund may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so even in cases where the unaffiliated Underlying Funds incur lower fees or have achieved better historical investment performance than the comparable affiliated Underlying Funds. If the Fund invests in an Underlying Fund with higher expenses, the Fund’s performance would be lower than if the Fund had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance).Asset Allocation: Investment performance depends on the manager’s skill in allocating assets among the asset classes in which the Fund invests and in choosing investments within those asset classes. There is a risk that the manager may allocate assets or investments to or within an asset class that underperforms compared to other asset classes or investments.Bank Instruments: Bank instruments include certificates of deposit, fixed time deposits, bankers’ acceptances, and other debt and deposit-type obligations issued by banks. Changes in economic, regulatory, or political conditions, or other events that affect the banking industry may have an adverse effect on bank instruments or banking institutions that serve as counterparties in transactions with the Fund.Cash/Cash Equivalents: Investments in cash or cash equivalents may lower returns and result in potential lost opportunities to participate in market appreciation which could negatively impact the Fund’s performance and ability to achieve its investment objective.Commodities: Commodity prices can have significant volatility, and exposure to commodities can cause the net asset value of the Fund’s shares to decline or fluctuate in a rapid and unpredictable manner. A liquid secondary market may not exist for certain commodities, which may make it difficult for the Fund to sell them at a desirable price or time.Company: The price of a company’s stock could decline or underperform for many reasons , including, among others, poor management, financial problems, reduced demand for the company’s goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.Credit: The Fund could lose money if the issuer or guarantor of a fixed income security , or the counterparty to a derivative contract, is unable or unwilling, or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise)as unable or unwilling, to meet its financial obligations.Credit Default Swaps: The Fund may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a credit default swap is generally obligated to pay the seller an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default , on a reference obligation has occurred . If a credit event occurs, the seller generally must pay the buyer the “ par value ” ( full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount if the swap is cash settled. As a seller of a credit default swap, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity, and leveraging risks and the risk that the swap may not correlate with its reference obligation as expected. Certain standardized credit default swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that it will achieve that result, and, in the meantime, central clearing and related requirements expose the Fund to new kinds of costs and risks. In addition, credit default swaps expose the Fund to the risk of improper valuation.Currency: To the extent that the Fund invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Fund through foreign currency exchange transactions.Deflation: Deflation occurs when prices throughout the economy decline over time — the opposite of inflation. Unless repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed, when there is deflation, the principal and income of an inflation-protected bond will decline and could result in losses.Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying asset, reference rate, or index credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the asset, reference rate, or index being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment.Environmental, Social and/or Governance (funds-of-funds): Consideration by the Sub-Adviser of ESG factors in selecting Underlying Funds may cause the Fund to forgo Underlying Funds that other investors that do not consider similar factors or that evaluate them differently might select.  This may cause the Fund to underperform the securities markets generally or other funds-of-funds whose advisers do not consider ESG factors or use such factors differently. It is possible that performance of the Underlying Funds identified through the Sub-Adviser’s consideration of ESG factors will be less favorable than the Sub-Adviser might have anticipated. The Sub-Adviser’s consideration of ESG factors in selecting Underlying Funds may have an adverse effect on the Fund’s performance.Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan (which can include certain bank loans), the Fund will experience a reduction in its income and a decline in the market value of such floating rate loan. If a floating rate loan is held by the Fund through another financial institution, or the Fund relies upon another financial institution to administer the loan, the receipt of scheduled interest or principal payments may be subject to the credit risk of such financial institution. Investors in floating rate loans may not be afforded the protections of the anti-fraud provisions of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, because loans may not be considered “securities” under such laws. Additionally, the value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the borrower’s obligations under the loan, and such collateral may be difficult to liquidate. No active trading market may exist for many floating rate loans and many floating rate loans are subject to restrictions on resale. Transactions in loans typically settle on a delayed basis and may take longer than 7 days to settle. As a result, the Fund may not receive the proceeds from a sale of a floating rate loan for a significant period of time. Delay in the receipts of settlement proceeds may impair the ability of the Fund to meet its redemption obligations, and may limit the ability of the Fund to repay debt, pay dividends, or to take advantage of new investment opportunities.Foreign (Non-U.S.) Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing , and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country,or region may adversely impact investments or issuers in another market, country, or region. Foreign (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets.Growth Investing: Prices of growth -oriented stocks are more sensitive to investor perceptions of the issuer’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth-oriented stocks tend to be more volatile than value-oriented stocks, and may underperform the market as a whole over any given time period.High-Yield Securities: Lower - quality securities (including securities that have fallen below investment grade and are classified as “junk bonds” or “high-yield securities”) have greater credit risk and liquidity risk than higher-quality (investment grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower-quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity risk and price volatility.Index Strategy: An Underlying Fund that seeks to track an index’s performance and does not use defensive strategies or attempt to reduce its exposure to poor performing securities in an index may underperform the overall market. To the extent an Underlying Fund’s investments track its target index, such Underlying Index Fund may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Fund. The correlation between the Fund’s performance and index performance may be affected by the Fund’s expenses and the timing of purchases and redemptions of the Fund’s shares. The correlation between an Underlying Index Fund’s performance and index performance will be reduced by the Underlying Index Fund’s expenses and could be reduced by the timing of purchases and redemptions of the Underlying Index Fund’s shares. In addition, an Underlying Index Fund’s actual holdings might not match the index and an Underlying Index Fund’s effective exposure to index securities at any given time may not precisely correlate. When deciding between Underlying Index Funds benchmarked to the same index, the manager may not select the Underlying Index Fund with the lowest expenses. If the Fund invests in an Underlying Index Fund with higher expenses, the Fund's performance would be lower than if the Fund had invested in an Underlying Index Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance).Inflation-Indexed Bonds: If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently, the interest payable on these bonds (calculated with respect to a smaller principal amount) will be reduced. In addition, inflation-indexed bonds are subject to the usual risks associated with debt instruments, such as interest rate and credit risk. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed rate debt instruments ; conversely, values generally rise as market interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to changes in market interest rates. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the United States is experiencing a rising market interest rate environment, which may increase the Fund’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Fund invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in fixed-income markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the fixed-income markets. Further, recent and potential future changes in government policy may affect interest rates. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Fund’s operations and return potential.Liquidity: If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, or at all, which could cause the Fund to lose money. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Fund to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Fund. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress.London Inter-Bank Offered Rate: The obligations of the parties under many financial arrangements, such as debt instruments (including senior loans) and derivatives, may be determined based, in whole or in part, on the London Inter-Bank Offered Rate (“LIBOR”). In 2017, the UK Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in many major currencies, including for example, the Secured Overnight Funding Rate (“SOFR”) for U.S. dollar LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement market. SOFR is published in various forms, including as a daily, compounded, and forward-looking term rate. The discontinuance of LIBOR and the adoption/implementation of alternative rates pose a number of risks, including, among others, whether any substitute rate will experience the market participation and liquidity necessary to provide a workable substitute for LIBOR; the effect on parties’ existing contractual arrangements, hedging transactions, and investment strategies generally from a conversion from LIBOR to alternative rates; the effect on the Fund’s existing investments, including the possibility that some of those investments may terminate or their terms may be adjusted to the disadvantage of the Fund; and the risk of general market disruption during the transition period. Markets relying on alternative rates are developing slowly and may offer limited liquidity. The general unavailability of LIBOR and the transition away from LIBOR to alternative rates could have a substantial adverse impact on the performance of the Fund.Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory, or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the Fund to achieve its investment objectives.Market Capitalization: Stocks fall into three broad market capitalization categories: large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.Market Disruption and Geopolitical: The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the U.S. Wars, terrorism, global health crises and pandemics, and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S.,and global economies and markets, generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of the Fund’s investments, including beyond the Fund’s direct exposure to Russian issuers or nearby geographic regions. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. Those events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund’s investments. Any of these occurrences could disrupt the operations of the Fund and of the Fund’s service providers.Natural Resources/Commodity Securities: The operations and financial performance of companies in natural resources industries may be directly affected by commodity prices. This risk is exacerbated for those natural resources companies that own the underlying commodity.Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of an investment company’s underlying investments might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund. The investment policies of the other investment companies may not be the same as those of the Fund; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Fund is typically subject.Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This risk is heightened in a falling market interest rate environment. Prepayment may expose the Fund to a lower rate of return upon reinvestment of principal. Also, if a debt instrument subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Extension risk is the risk that the issuer of a debt instrument will pay back the principal later than expected. This risk is heightened in a rising market interest rate environment. This may negatively affect performance, as the value of the debt instrument decreases when principal payments are made later than expected. Additionally, the Fund may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.Real Estate Companies and Real Estate Investment Trusts: Investing in real estate companies and REITs may subject the Fund to risks similar to those associated with the direct ownership of real estate, including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, market interest rates, zoning laws, regulatory limitations on rents, property taxes, environmental problems, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.U.S. Government Securities and Obligations: U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies, or government-sponsored enterprises. U.S. government securities are subject to market risk and interest rate risk, and may be subject to varying degrees of credit risk.Value Investing: Securities that appear to be undervalued may never appreciate to the extent expected. Further, because the prices of value-oriented securities tend to correlate more closely with economic cycles than growth-oriented securities, they generally are more sensitive to changing economic conditions, such as changes in market interest rates, corporate earnings and industrial production. The manager may be wrong in its assessment of a company’s value and the securities the Fund holds may not reach their full values. Risks associated with value investing include that a security that is perceived by the manager to be undervalued may actually be appropriately priced and, thus, may not appreciate and provide anticipated capital growth. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Fund’s relative performance may suffer. There is a risk that funds that invest in value-oriented securities may underperform other funds that invest more broadly.An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the changes in the Fund's performance from year to year, and the table compares the Fund's performance to the performance of a broad-based securities market index/indices with investment characteristics similar to those of the Fund for the same period. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund's Class I shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses. The Class A and Class R shares performance shown for the period prior to their inception date is the performance of Class I shares adjusted for any differences in the expenses between the classes. The Class R6 shares performance shown for the period prior to their inception date is the performance of Class I shares without adjustment for any differences in the expenses between the two classes. If adjusted for such differences, returns would be different.Because Class T shares of the Fund had not commenced operations as of the calendar year ended December 31, 2021, no performance information for Class T shares is provided below.The Fund’s performance prior to April 27, 2021 reflects returns achieved pursuant to different principal investment strategies. If the Fund’s current strategies had been in place for the prior periods, the performance information shown would have been different. The Fund's past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to www.individuals.voya.com/literature or call 1-800-992-0180.
