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 Expense Example, affect the Fund's performance.During the most recent fiscal year, the Fund's portfolio turnover rate was 70% 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 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	Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of equity securities. The Fund invests primarily in equity securities included in the MSCI World Value IndexSM (the “Index”). The Fund invests in securities of issuers in a number of different countries, including the United States. The sub-adviser (the “Sub-Adviser”) seeks to maximize total return to the extent consistent with maintaining lower volatility than the Index. Volatility generally measures how much a fund’s returns have varied over a specified time frame. The Fund may invest in derivative instruments, including, but not limited to, index futures. The Fund typically uses derivatives as a substitute for purchasing securities included in the Index or for the purpose of maintaining equity market exposure on its cash balance. The Fund may invest in real estate-related securities, including real estate investment trusts (“REITs”). The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. The Sub-Adviser creates a target universe that consists of dividend paying securities by screening for companies that exhibit stable dividend yields within each industry sector. Once the Sub-Adviser creates this target universe, the Sub-Adviser seeks to identify the most attractive securities within various geographic regions and sectors by ranking each security relative to other securities within its region or sector, as applicable, using proprietary fundamental sector-specific quantitative investment models. The Sub-Adviser then uses optimization techniques to seek to achieve the Fund’s target dividend yield, which is expected to be higher than the Index in aggregate, manage target beta, determine active weights, and neutralize region and sector exposures in order to create a portfolio that the Sub-Adviser believes will provide the potential for maximum total return consistent with maintaining lower volatility than the Index. Under certain circumstances, the Fund will likely earn a lower level of total return than it would in the absence of its strategy of maintaining a relatively low level of volatility. In evaluating investments for the Fund, the Sub-Adviser, through its quantitative methods and models, takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of a company. Among the factors considered, the Sub-Adviser expects that its quantitative methods and models will typically take into account environmental, social, and governance (“ESG”) factors. In considering ESG factors, the Sub-Adviser’s quantitative methods and models will rely primarily on factors identified through the Sub-Adviser’s proprietary empirical research and on third-party evaluations of a company’s ESG standing. ESG factors will be only one of many considerations in the evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in a company, if at all, will depend on the operation of the Sub-Adviser’s quantitative processes and the judgment of the Sub-Adviser. The Fund may lend portfolio securities on a short-term or long-term basis, up to 30% of its total assets.

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 and an additional index  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 A shares. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. Performance for other share classes would differ to the extent they have differences in their fees and expenses. 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 expenses between the two classes. If adjusted for such differences, returns would be different.The Fund’s performance prior to December 31, 2020 reflects returns achieved pursuant to different principal investment strategies. The Fund’s performance prior to May 1, 2018 reflects returns achieved pursuant to different principal investment strategies. The Fund’s performance prior to May 1, 2016 reflects returns achieved pursuant to different principal investment strategies. If the Fund’s current sub-adviser and 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 https://individuals.voya.com/literature or call 1-800-992-0180.

Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Company Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Currency Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Derivative Instruments Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Dividend Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Dividend: Companies that issue dividend yielding equity securities are not required to continue to pay dividends on such securities. Therefore, there is a possibility that such companies could reduce or eliminate the payment of dividends in the future. As a result, the Fund’s ability to execute its investment strategy may be limited.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Environmental Social and Governance Quantitative [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Environmental, Social, and Governance (Quantitative): The Sub-Adviser’s consideration of ESG factors in selecting investments for the Fund depends on the operation of quantitative methods and models whose design reflects qualitative and subjective judgments of the Sub-Adviser, including reliance on, or incorporation of, data in respect of ESG factors that may rely on third-party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of the Fund’s assets that will be invested in companies that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may not invest in companies that compare favorably to other companies on the basis of ESG factors. It is possible that the Fund will have less exposure to certain companies due to the Sub-Adviser’s assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Foreign Non US Investments Developing and Emerging Markets Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign (Non-U.S.) Investments: 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 the threat of new or modified 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.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Investment Model Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Investment Model: The Sub-Adviser’s proprietary investment model may not adequately take into account existing or unforeseen market factors or the interaction among such factors, including changes in how such factors interact, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for the Fund. Volatility management techniques may not always be successful in reducing volatility, may not protect against market declines, and may limit the Fund’s participation in market gains, negatively impacting performance even during periods when the market is rising. During sudden or significant market rallies, such underperformance may be significant. Moreover, volatility management strategies may increase portfolio transaction costs, which may increase losses or reduce gains. The Fund’s volatility may not be lower than that of the Fund’s Index during all market cycles due to market factors. Funds that are actively managed, in whole or in part, according to a quantitative investment model (including models that utilize forms of artificial intelligence, such as machine learning) can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Liquidity Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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. 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, which could cause the Fund to lose money. 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. Certain securities that are liquid when purchased may later become illiquid, particularly in times of overall economic distress or due to geopolitical events such as sanctions, trading halts, or wars. In addition, markets or securities may become illiquid quickly.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt instruments. 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.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Market Capitalization Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Market Disruption and Geopolitical Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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 United States. Wars, terrorism, global health crises and pandemics, tariffs and other restrictions on trade or economic sanctions, rapid technological developments (such as artificial intelligence technologies), 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 resulted 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. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. 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. Furthermore, the prolonged conflict between Hamas and Israel, and the potential expansion of the conflict in the surrounding areas and the involvement of other nations in such conflict, such as the Houthi movement's attacks on marine vessels in the Red Sea, could further destabilize the Middle East region and introduce new uncertainties in global markets, including the oil and natural gas markets. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These 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.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Other Investment Companies Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Other Investment Companies: The main risk of investing in other investment companies, including 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 Fund’s expenses. 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. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF’s shares, which could cause a material decline in the ETF’s net asset value.
Class A C I R6 T and WP Shares | Voya Global High Dividend Low Volatility Fund | Real Estate Companies and Real Estate Investment Trusts Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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, 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 of the REIT’s sponsor. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Securities Lending: Securities lending involves two primary risks: “ investment risk ” and “ borrower default risk. ” When lending securities, the Fund will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks.

[1] A contingent deferred sales charge of 1.00% is assessed on certain redemptions of Class A shares made within 18 months after purchase where no initial sales charge was paid at the time of purchase as part of an investment of $1,000,000 or more.

[2] Voya Investments, LLC (the “Investment Adviser”) and distributor are contractually obligated to limit expenses to 0.85%, 1.60%, 0.60%, 0.57%, and 0.60% for Class A, Class C, Class I, Class R6, and Class W shares, respectively, through March 1, 2026. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and Acquired Fund Fees and Expenses. This limitation is subject to possible recoupment by the Investment Adviser and distributor within 36 months of the waiver or reimbursement. The amount of the recoupment is limited to the lesser of the amounts that would be recoupable under: (i) the expense limitation in effect at the time of the waiver or reimbursement; or (ii) the expense limitation in effect at the time of recoupment. Termination or modification of this obligation requires approval by the Fund’s Board of Trustees (the “Board”).

[3] The index returns include the reinvestment of dividends and distributions net of withholding taxes, but do not reflect fees, brokerage commissions, or other expenses.

[4] Effective commencing with shareholder reports filed and transmitted to shareholders after July 24, 2024, the Investment Adviser changed the primary benchmark from the MSCI World Value Index to the MSCI All Country World Index in accordance with changes to regulatory disclosure requirements. The Fund continues to use the MSCI World Value Index as an additional benchmark that the Investment Adviser believes more closely reflects the Fund’s principal investment strategies.
