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 247% 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	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in bonds of issuers in a number of different countries, which may include the United States. The Fund will provide shareholders with at least 60 days' prior written notice of any change in this investment policy. The Fund may invest in securities of issuers located in developed and emerging market countries. Securities may be denominated in foreign currencies or in U.S. dollars. The Fund may hedge its exposure to securities denominated in foreign currencies. The Fund may also borrow money from banks and invest the proceeds of such loans in portfolio securities to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and applicable exemptive orders thereunder (“1940 Act”). This investment technique is known as “leveraging.” The Fund invests primarily in investment-grade securities which include, but are not limited to, corporate and government bonds which, at the time of investment, are rated investment-grade (at least BBB- by S&P Global Ratings or Baa3 by Moody's Investors Service, Inc.) or have an equivalent rating by a nationally recognized statistical rating organization, or are of comparable quality if unrated. The Fund may also invest in preferred stocks, money market instruments, municipal bonds, commercial and residential mortgage-related securities, asset-backed securities, other securitized and structured debt products, private placements, sovereign debt, and other investment companies. The Fund may also invest its assets in bank loans and in a combination of floating rate secured loans (“Senior Loans”) and shares of Voya Prime Rate Trust, a closed-end investment company managed by the Adviser that invests in Senior Loans. Although the Fund may invest a portion of its assets in high-yield debt securities rated below investment-grade (commonly referred to as “junk bonds”), the Fund will seek to maintain a minimum weighted average portfolio quality rating of at least investment-grade. The dollar-weighted average portfolio duration of the Fund will generally range between two and nine years. Duration is the most commonly used measure of risk in fixed-income investments as it incorporates multiple features of the fixed-income instrument (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are expected to be received. The weights are the amounts of the payments discounted by the yield-to-maturity of the fixed-income instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest-rate risk or reward for the fixed-income instrument prices. For example, the price of a bond with an average duration of five years would be expected to fall approximately 5% if interest rates rose by one percentage point. Conversely, the price of a bond with an average duration of five years would be expected to rise approximately 5% if interest rates drop by one percentage point. The Fund may use derivatives, including futures, swaps (including interest rate swaps, total return swaps, and credit default swaps), and options, among others, to seek to enhance return, to hedge some of the risks of its investments in fixed-income securities, or as a substitute for a position in an underlying asset. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls and reverse repurchase agreements). The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the 1940 Act. The investment process focuses on allocating assets among various sectors of the global bond markets and buying bonds at a discount to their intrinsic value. The sub-adviser (“Sub-Adviser”) utilizes proprietary quantitative techniques to identify bonds or sectors that are cheap relative to other bonds or sectors based on their historical price relationships. Teams of asset specialists use this relative value analysis to guide them in the security selection process. The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others. The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1⁄3% of its total assets.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds. 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. Borrowing: Borrowing creates leverage, which may increase expenses and increase the impact of the Fund’s other risks. The use of leverage may exaggerate any increase or decrease in the Fund’s net asset value causing the Fund to be more volatile than a fund that does not borrow. Borrowing for investment purposes is considered to be speculative and may result in losses to the Fund. 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 company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless. Credit: The price of a bond or other debt instrument is likely to fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay its financial obligations altogether. Credit Default Swaps: A Fund may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a swap pays a fee to buy protection against the risk that a security will default. If no default occurs, the Fund will have paid the fee, but typically will recover nothing under the swap. A seller of a swap receives payment(s) in return for an obligation to pay the counterparty the full notional value of a security in the event of a default of the security issuer. As a seller of a 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 underlying asset as expected. Certain standardized 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 central clearing 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. Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity 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 currency, security or other risk 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. In addition, given their complexity, derivatives expose the Fund to the risk of improper valuation. Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan, the Fund will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid and may lead to a decline in the net asset value. 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 issuer’s obligations under the loan. Furthermore, 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. It may also limit the ability of the Fund to repay debt, pay dividends, or to take advantage of new investment opportunities. Foreign 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 to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States 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 investment risks may be greater in developing and emerging markets than in developed markets. 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 and price volatility risk. Interest in Loans: The value and the income streams of interests in loans (including participation interests in lease financings and assignments in secured variable or floating rate loans) will decline if borrowers delay payments or fail to pay altogether. A significant rise in market interest rates could increase this risk. Although loans may be fully collateralized when purchased, such collateral may become illiquid or decline in value. Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; 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 interest rate risk. In the case of inverse securities, the interest rate paid by the securities is a floating rate, which generally will decrease when the market rate of interest to which the inverse security is indexed increases and will increase when the market rate of interest to which the inverse security is indexed decreases. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Fund’s exposure to risks associated with rising market interest rates. Rising market interest rates could 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. Investing through Bond Connect: Chinese debt instruments trade on the China Interbank Bond Market (“CIBM”) and may be purchased through a market access program that is designed to, among other things, enable foreign investment in the People’s Republic of China (“Bond Connect”). There are significant risks inherent in investing in Chinese debt instruments, similar to the risks of other fixed-income securities markets in emerging markets. The prices of debt instruments traded on the CIBM may fluctuate significantly due to low trading volume and potential lack of liquidity. The rules to access debt instruments that trade on the CIBM through Bond Connect are relatively new and subject to change, which may adversely affect the Fund 's ability to invest in these instruments and to enforce its rights as a beneficial owner of these instruments. Trading through Bond Connect is subject to a number of restrictions that may affect the Fund’s investments and returns. Investment Model: A manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. Funds that are actively managed, in whole or in part, according to a quantitative investment model can perform differently from the market as a whole 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. There is no guarantee that the use of these investment models will result in effective investment decisions for the Fund. 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 price at which it sells illiquid securities will be less than the price at which they were valued when held by the Fund. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. A Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to 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 in these areas 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-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger 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 larger companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns. Mortgage- and/or Asset-Backed Securities: Defaults on, or low credit quality or liquidity of the underlying assets of the asset-backed (including mortgage-backed) securities may impair the value of these securities and result in losses. There may be limitations on the enforceability of any security interest or collateral granted with respect to those underlying assets and the value of collateral may not satisfy the obligation upon default. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of debt instruments. Municipal Obligations: The municipal securities market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities. Among other risks, investments in municipal securities are subject to the risk that the issuer may delay payment, restructure its debt, or refuse to pay interest or repay principal on its debt. Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company 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 may occur when interest rates decline. 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 may occur when interest rates rise. 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. Restricted Securities: Securities that are not registered for sale to the public under the Securities Act of 1933, as amended, are referred to as “restricted securities.” These securities may be sold in private placement transactions between issuers and their purchasers and may be neither listed on an exchange nor traded in other established markets. Many times these securities are subject to legal or contractual restrictions on resale. As a result of the absence of a public trading market, the prices of these securities may be more volatile, less liquid and more difficult to value than publicly traded securities. The price realized from the sale of these securities could be less than the amount originally paid or less than their fair value if they are resold in privately negotiated transactions. In addition, these securities may not be subject to disclosure and other investment protection requirements that are afforded to publicly traded securities. Certain investments may include investment in smaller, less seasoned issuers, which may involve greater risk. 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. Sovereign Debt: These securities are issued or guaranteed by foreign government entities. Investments in sovereign debt are subject to the risk that a government entity may delay payment, restructure its debt, or refuse to pay interest or repay principal on its sovereign debt. Some of these reasons may include cash flow problems, insufficient foreign currency reserves, political considerations, social changes, the relative size of its debt position to its economy or its failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a government entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debts that a government does not pay or bankruptcy proceeding by which all or part of sovereign debt that a government entity has not repaid may be collected. 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.
