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 Portfolio invests at least 99.5% of its total assets in government securities, cash and repurchase agreements collateralized fully by government securities or cash. For purposes of this policy, “government securities” mean any securities issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an agency or instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States; or any certificate of deposit for any of the foregoing.In addition, under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in government securities and repurchase agreements that are collateralized by government securities. The Portfolio will provide shareholders with at least 60 days’ prior notice of any change in this investment policy.The Portfolio invests in a portfolio of securities maturing in 397 days or less (with certain exceptions) that will have a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. The Portfolio may invest in variable and floating rate instruments, and transact in securities on a when-issued, delayed delivery or forward commitment basis.The securities purchased by the Portfolio are subject to the quality, diversification, and other requirements of Rule 2a-7 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 “1940 Act”). Portfolio investments of the Portfolio are valued based on the amortized cost valuation method pursuant to Rule 2a-7 under the 1940 Act.The Portfolio may maintain a rating from one or more rating agencies that provide ratings on money market funds. There can be no assurance that the Portfolio will maintain any particular rating or maintain it with a particular rating agency. To maintain a rating, the sub-adviser (the “Sub-Adviser”) may manage the Portfolio more conservatively than if it was not rated.The Portfolio may invest in other investment companies that are money market funds to the extent permitted under the 1940 Act.In choosing investments for the Portfolio, the Sub-Adviser employs a disciplined, four-step investment process designed to ensure preservation of capital and liquidity, as well as adherence to regulatory requirements. The four steps are: first, a formal list of approved issuers is actively maintained; second, securities of issuers on the approved list that meet the Portfolio’s guidelines are selected for investment; third, diversification is continuously monitored to ensure that regulatory limits are not exceeded; and finally, portfolio maturity decisions are made based upon expected cash flows, income opportunities available in the market, and expectations of future interest rates.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following information is intended to help you understand the risks of investing in the Portfolio. The following bar chart shows the changes in the Portfolio's performance from year to year, and the table provides additional performance information.The Portfolio'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 Portfolio's Class I shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses.Performance shown in the bar chart and in the Average Annual Total Returns table does not include insurance-related charges imposed under a Variable Contract or expenses related to a Qualified Plan. If these charges or expenses were included, performance would be lower. Thus, you should not compare the Portfolio's performance directly with the performance information of other investment products without taking into account all insurance-related charges and expenses payable under your Variable Contract or Qualified Plan. The Portfolio's past performance is no guarantee of future results.Prior to May 1, 2016, the Portfolio operated as a prime money market fund and invested in certain types of securities that the Portfolio is no longer permitted to hold. Consequently, the performance information below may have been different if the current investment limitations had been in effect during the period prior to the Portfolio’s conversion to a government money market fund.

Voya Government Money Market Portfolio | Risk Money Market Fund Sponsor May Not Provide Support [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	The Portfolio’s sponsor is not required to reimburse the Portfolio for losses, and you should not expect that the sponsor will provide financial support to the Portfolio at any time, including during periods of market stress.
Voya Government Money Market Portfolio | Risk Not Insured [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	An investment in the Portfolio is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Voya Government Money Market Portfolio | Cash Cash Equivalents Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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 Portfolio’s performance and ability to achieve its investment objective.
Voya Government Money Market Portfolio | Credit Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Credit: The Portfolio could lose money if the issuer or guarantor of a debt instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, 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.
Voya Government Money Market Portfolio | Interest Rate Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other debt instruments; conversely, values generally rise as market interest rates fall. Interest rate risk is generally greater for debt instruments than floating-rate instruments. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is 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 U.S. has recently experienced a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose debt and related markets to heightened volatility. To the extent that the Portfolio invests in debt instruments, 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 Portfolio to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in debt markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in debt 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 debt and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose debt and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
Voya Government Money Market Portfolio | 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 interplay between such factors, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for the Portfolio.
Voya Government Money Market Portfolio | Liquidity Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity: If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio’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 Portfolio 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 Portfolio, which could cause the Portfolio 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.
Voya Government Money Market Portfolio | Market Disruption and Geopolitical Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Disruption and Geopolitical: The Portfolio 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, 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 Portfolio’s investments, including beyond the Portfolio’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. A number of U.S. domestic banks and foreign (non-U.S.) banks have recently 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 Portfolio’s investments. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers.
Voya Government Money Market Portfolio | Money Market Regulatory Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Money Market Regulatory: Changes in government regulations may adversely affect the value of a security held by the Portfolio. The SEC has adopted amendments to money market fund regulation that permit the Portfolio to impose discretionary liquidity fees, increase the Portfolio’s daily and weekly liquid asset minimum requirements and eliminate the ability of the Portfolio to temporarily suspend redemptions due to declines in the Portfolio's weekly liquid assets, among other changes. As of the date of this Prospectus, the Board has elected not to subject the Portfolio to such discretionary liquidity fees. These changes may result in reduced yields for money market funds, including the Portfolio, which may invest in other money market funds. The SEC or other regulators may adopt additional money market fund reforms, which may impact the structure and operation or performance of the Portfolio.
Voya Government Money Market Portfolio | Other Investment Companies Money Market Funds Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Other Investment Companies (Money Market Funds): A money market fund may only invest in other investment companies that qualify as money market funds under Rule 2a-7 of the 1940 Act, and there is a risk that such money market funds may not comply with Rule 2a-7. 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 Portfolio. The investment policies of the other investment companies may not be the same as those of the Portfolio; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Portfolio is typically subject.
Voya Government Money Market Portfolio | Prepayment and Extension Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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 Portfolio 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 Portfolio may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.
Voya Government Money Market Portfolio | Repurchase Agreements Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Repurchase Agreements: In the event that the other party to a repurchase agreement defaults on its obligations, the Portfolio would generally seek to sell the underlying security serving as collateral for the repurchase agreement. However, the value of collateral may be insufficient to satisfy the counterparty's obligation and/or the Portfolio may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security, which could result in a loss. In addition, if the Portfolio is characterized by a court as an unsecured creditor, it would be at risk of losing some or all of the principal and interest involved in the transaction.
Voya Government Money Market Portfolio | US Government Securities and Obligations Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
Voya Government Money Market Portfolio | When Issued Delayed Delivery and Forward Commitment Transactions Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	When-Issued, Delayed Delivery, and Forward Commitment Transactions: When-issued, delayed delivery , and forward commitment transactions involve the risk that the security the Portfolio buys will lose value prior to its delivery. These transactions may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of the Portfolio’s other risks. There also is the risk that the security will not be issued or that the other party will not meet its obligation. If this occurs, the Portfolio loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

[1] Voya Investments, LLC (the “Investment Adviser”) and the distributor are contractually obligated to waive a portion of their advisory fees and distribution and/or shareholder servicing fees, as applicable, and to reimburse certain expenses of the Portfolio to the extent necessary to assist the Portfolio in maintaining a net yield of not less than zero through May 1, 2025. There is no guarantee that the Portfolio will maintain such a yield. Any advisory fees waived or expenses reimbursed may be subject to possible recoupment by the Investment Adviser 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. In no event will the amount of the recoupment on any day exceed 20% of the yield (net of all expenses) of the Portfolio on that day. The Investment Adviser is contractually obligated to waive 0.045% of the management fee through May 1, 2025. Termination or modification of these obligations requires approval by the Portfolio’s Board of Trustees (the “Board”).
