Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 73% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year, that the Fund's operating expenses remain the same (except that fee waivers or reimbursements, if any, are only reflected in the 1-Year figures) and that all dividends and distributions are reinvested. Your actual costs may be higher or lower.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its investable assets in U.S. Treasury Inflation-Protected Securities (“TIPS”). In pursuit of this investment policy, the Fund may invest a large percentage of its investable assets in securities held within the Bloomberg US Treasury Inflation-Protected (TIPS) Index (the “Index”). The Fund is not sponsored by or affiliated with Bloomberg, the provider of the Index.The term “investable assets” in this Prospectus refers to the Fund's net assets plus any borrowings for investment purposes. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions.Consistent with the Fund's investment objective, the subadviser seeks diversified investment exposure to TIPS with the potential for incremental gains relative to the Index. The subadviser relies on a quantitatively driven approach. Through proprietary analytics, the subadviser attempts to exploit relative value opportunities and trading inefficiencies, while limiting risk exposures.The Fund may also hold non inflation-indexed securities, although these will normally not exceed 20% of the Fund's total assets. The investments may be public or private securities.TIPS are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation — a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the Non Seasonally Adjusted Consumer Price Index (“NSA CPI”), and TIPS’ principal payments are adjusted according to changes in the NSA CPI. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds. The Fund’s income may decline due to a decline in Consumer Price Index for Urban Consumers (“CPI-U”), also known as deflation”. If there is deflation, the principal value of an inflation-linked security will be adjusted downward, and consequently the interest payments (calculated with respect to a smaller principal amount) will be reduced. The principal value can decrease, but not below the original face value of the security. The Index includes all publicly issued TIPS that have at least one year remaining to maturity, are rated investment grade and have $250 million or more of outstanding face value. In addition, the securities in the Index must be denominated in U.S. dollars and must be fixed rate and non-convertible.While the Fund’s portfolio is structured to have similar overall characteristics to the Index, the portfolio managers may adjust certain holdings in relation to their weighting in the Index and use other investment strategies in an attempt to generate outperformance over the Index. Based on the portfolio managers’ views as to the relative value or attractiveness of a specific security as well as an internal proprietary analytics model, the Fund places a slightly greater or lesser emphasis on certain Index securities than their representation in the Index. This could result in the Fund being underweight or overweight in certain TIPS versus the Index.All fixed income securities held in the Fund will be investment grade or higher. The Fund may also acquire U.S. Government securities in the form of custodial receipts that show ownership of future interest payments, principal payments or both on certain U.S. Treasury notes or bonds. Such notes or bonds are held in custody by a bank on behalf of the owners. These custodial receipts are commonly referred to as Treasury strips.The Fund may also invest in other debt obligations issued or guaranteed by the U.S. Government and government-related entities. Some (but not all) of these debt securities are backed by the full faith and credit of the U.S. Government.The Fund has no limitations with respect to the maturities of portfolio securities in which it may invest. The Fund may actively and frequently trade its portfolio securities.In managing the Fund’s assets, the subadviser uses a combination of top-down economic analysis and bottom-up research in conjunction with proprietary quantitative models and risk management systems. In the top-down economic analysis, the subadviser develops views on economic, policy and market trends. In its bottom-up research, the subadviser develops an internal rating and outlook on issuers. The rating and outlook are determined based on a thorough review of the financial health and trends of the issuer. The subadviser may also consider investment factors such as expected total return, yield, spread and potential for price appreciation as well as credit quality, maturity and risk. The Fund may invest in a security based upon the expected total return rather than the yield of such security.
Risk [Heading]	rr_RiskHeading	<span style="font-family:Arial;font-size:9.70pt;font-weight:bold;">Principal Risks. </span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	All investments have risks to some degree. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day-to-day and over time.You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; and is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks of investing in the Fund.The order of the below risk factors does not indicate the significance of any particular risk factor.Active Trading Risk. The Fund actively and frequently trades its portfolio securities. High portfolio turnover involves correspondingly greater brokerage commissions and other transaction costs, which are borne directly by the Fund; which can affect the Fund’s performance and have adverse tax consequences. In addition, high portfolio turnover may also mean that a proportionately greater amount of distributions to shareholders will be taxed as ordinary income rather than long-term capital gains compared to investment companies with lower portfolio turnover.Adjustable and Floating Rate Securities Risk. The value of adjustable and floating rate securities may lag behind the value of fixed rate securities when interest rates change. Such securities may be subject to extended settlement periods (longer than seven days) and in unusual market conditions, with a high volume of shareholder redemptions, may present a risk of loss to the Fund or may impair the Fund’s ability satisfy shareholder redemption requests.Credit Risk. This is the risk that the issuer, the guarantor or the insurer of a fixed income security, or the counterparty to a contract, may be unable or unwilling to make timely principal and interest payments, or to otherwise honor its obligations. Additionally, fixed income securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer or counterparty to pay back debt. The lower the credit quality of a bond, the more sensitive it is to credit risk.Debt Obligations Risk. Debt obligations are subject to credit risk, market risk and interest rate risk. The Fund's holdings, share price, yield and total return may also fluctuate in response to bond market movements. The value of bonds may decline for issuer-related reasons, including management performance, financial leverage and reduced demand for the issuer’s goods and services. Certain types of fixed income obligations also may be subject to “call and redemption risk,”which is the risk that the issuer may call a bond held by the Fund for redemption before it matures and the Fund may not be able to reinvest at the same rate of interest and therefore would earn less income.Derivatives Risk. Derivatives involve special risks and costs and may result in losses to the Fund. The successful use of derivatives requires sophisticated management, and, to the extent that derivatives are used, the Fund will depend on the subadviser’s ability to analyze and manage derivatives transactions. The prices of derivatives may move in unexpected ways, especially in abnormal market conditions. Some derivatives are “leveraged” or may create economic leverage for the Fund. and therefore may magnify or otherwise increase investment losses to the Fund. The Fund's use of derivatives may also increase the amount of taxes payable by shareholders.Other risks arise from the potential inability to terminate or sell derivatives positions. A liquid secondary market may not always exist for the Fund's derivatives positions. In fact, many over-the-counter derivative instruments will not have liquidity beyond the counterparty to the instrument. Over-the-counter derivative instruments also involve the risk that the other party will not meet its obligations to the Fund. The use of derivatives also exposes the Fund to operational issues, such as documentation and settlement issues, systems failures, inadequate control and human error.Derivatives may also involve legal risks, such as insufficient documentation, the lack of capacity or authority of a counterparty to execute or settle a transaction, and the legality and enforceability of derivatives contracts. The U.S. Government and foreign governments have adopted (and may adopt further) regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements and risk exposure limitations. Regulation of derivatives may make derivatives more costly, limit their availability or utility to the Fund, or otherwise adversely affect their performance or disrupt markets.Economic and Market Events Risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth or the functioning of the securities markets, may at times result in unusually high market volatility, which could negatively impact performance. Relatively reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.Foreign Securities Risk. Investments in securities of non-U.S. issuers (including those denominated in U.S. dollars) may involve more risk than investing in securities of U.S. issuers. Foreign political, economic and legal systems, especially those in developing and emerging market countries, may be less stable and more volatile than in the United States. Foreign legal systems generally have fewer regulatory requirements than the U.S. legal system, particularly those of emerging markets. In general, less information is publicly available with respect to non-U.S. companies than U.S. companies. Non-U.S. companies generally are not subject to the same accounting, auditing, and financial reporting standards as are U.S. companies. Additionally, the changing value of foreign currencies and changes in exchange rates could also affect the value of the assets the Fund holds and the Fund's performance. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. Investments in emerging markets are subject to greater volatility and price declines.In addition, the Fund's investments in non-U.S. securities may be subject to the risks of nationalization or expropriation of assets, imposition of currency exchange controls or restrictions on the repatriation of non-U.S. currency, confiscatory taxation and adverse diplomatic developments. Special U.S. tax considerations may apply.Fund of Funds Risk. The Fund is an investment option for other PGIM Investments-advised mutual funds that are managed as “funds of funds.” As a result, from time to time, the Fund may experience relatively large redemptions and could be required to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of your investment to decline.Increase in Expenses Risk. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Active and frequent trading of Fund securities can increase expenses.Interest Rate Risk. The value of your investment may go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration debt securities. For example, a fixed income security with a duration of three years is expected to decrease in value by approximately 3% if interest rates increase by 1%. This is referred to as “duration risk.” When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as “prepayment risk.” When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Fund's holdings may fall sharply. This is referred to as “extension risk.” The Fund may lose money if short-term or long-term interest rates rise sharply or in a manner not anticipated by the subadviser.Large Shareholder and Large Scale Redemption Risk. Certain individuals, accounts, funds (including funds affiliated with the Manager) or institutions, including the Manager and its affiliates, may from time to time own or control a substantial amount of the Fund’s shares. There is no requirement that these entities maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy. The Fund’s ability to pursue its investment objective after one or more large scale redemptions may be impaired and, as a result, the Fund may invest a larger portion of its assets in cash or cash equivalents.Market Disruption and Geopolitical Risks. Market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including Russia’s military invasion of Ukraine), geopolitical developments (including trading and tariff arrangements, sanctions and cybersecurity attacks), instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally).The extent and duration of such events and resulting market disruptions cannot be predicted, but could be substantial and could magnify the impact of other risks to the Fund. These and other similar events could adversely affect the U.S. and foreign financial markets and lead to increased market volatility, reduced liquidity in the securities markets, significant negative impacts on issuers and the markets for certain securities and commodities and/or government intervention. They may also cause short- or long-term economic uncertainties in the United States and worldwide. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively impacted. Further, due to closures of certain markets and restrictions on trading certain securities, the value of certain securities held by the Fund could be significantly impacted, which could lead to such securities being valued at zero.COVID-19 and the related governmental and public responses have had and may continue to have an impact on the Fund’s investments and net asset value and have led and may continue to lead to increased market volatility and the potential for illiquidity in certain classes of securities and sectors of the market. They have also had and may continue to result in periods of business disruption, business closures, inability to obtain raw materials, supplies and component parts, and reduced or disrupted operations for the issuers in which the Fund invests. The occurrence, reoccurrence and pendency of public health epidemics could adversely affect the economies and financial markets either in specific countries or worldwide.Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.Mortgage-Backed and Asset-Backed Securities Risk. Mortgage-backed and asset-backed securities tend to increase in value less than other debt securities when interest rates decline, but are subject to similar risk of decline in market value during periods of rising interest rates. The values of mortgage-backed and asset-backed securities become more volatile as interest rates rise. In a period of declining interest rates, the Fund may be required to reinvest more frequent prepayments on mortgage-backed and asset-backed securities in lower-yielding investments.Reference Rate Risk. The Fund may be exposed to financial instruments that are tied to the London Interbank Offered Rate (“LIBOR”) to determine payment obligations, financing terms, hedging strategies or investment value.The United Kingdom's Financial Conduct Authority announced a phase out of LIBOR such that after June 30, 2023, the overnight, 1-month, 3-month, 6-month and 12-month U.S. dollar LIBOR settings will cease to be published or will no longer be representative. All other LIBOR settings and certain other interbank offered rates, such as the Euro Overnight Index Average (“EONIA”), ceased to be published or representative after December 31, 2021. The Fund may have investments linked to other interbank offered rates that may also cease to be published in the future. Various financial industry groups have been planning for the transition away from LIBOR, but there remain challenges to converting certain securities and transactions to a new reference rate (e.g., the Secured Overnight Financing Rate (“SOFR”), which is intended to replace the U.S. dollar LIBOR).Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for instruments whose terms currently include LIBOR as well as loan facilities used by the Fund. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Global regulators have advised market participants to cease entering into new contracts using LIBOR as a reference rate, and it is possible that investments in LIBOR-based instruments could invite regulatory scrutiny. In addition, a liquid market for newly-issued instruments that use a reference rate other than LIBOR still may be developing. There may also be challenges for the Fund to enter into hedging transactions against such newly-issued instruments until a market for such hedging transactions develops. All of the aforementioned may adversely affect the Fund's performance or net asset value.TIPS Risk. Inflation-indexed bonds, such as TIPS, generally decline in value when real interest rates rise. Real interest rates represent the nominal (stated) interest rates reduced by the expected impact of inflation. In certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, TIPS may experience greater losses than other fixed income securities with similar durations. In addition, any increase in principal value of an inflation-indexed bond caused by an increase in the price index is taxable in the year the increase occurs, even though the Fund generally will not receive cash representing the increase at that time. As a result, the Fund could be required at times to liquidate other investments, including when it is not advantageous to do so, in order to satisfy its distribution requirements as a regulated investment company under the Internal Revenue Code (“the Code”). Also, to the extent that the Fund invests in inflation-indexed bonds, income distributions are more likely to fluctuate.The Fund’s income may decline due to a decline in the Consumer Price Index for Urban Consumers (“CPI-U”), also known as deflation. If there is deflation, the principal value of an inflation-linked security will be adjusted downward, and consequently the interest payments (calculated with respect to a smaller principal amount) will be reduced. The principal value can decrease, but not below the original face value of the security. If inflation is lower than expected during the period the Fund holds an inflation-linked security, the Fund may earn less on the security than on a conventional bond.U.S. Government and Agency Securities Risk. U.S. Government and agency securities are subject to market risk, interest rate risk and credit risk. Not all U.S. Government securities are insured or guaranteed by the full faith and credit of the U.S. Government; some are only insured or guaranteed by the issuing agency, which must rely on its own resources to repay the debt. Some agency securities carry no guarantee whatsoever and the risk of default associated with these securities would be borne by the Fund. The maximum potential liability of the issuers of some U.S. Government securities held by the Fund may greatly exceed their current resources, including their legal right to support from the U.S. Treasury. No assurance can be given that the U.S. Government would provide financial support to any such issuers if it is not obligated to do so by law. It is possible that these issuers will not have the funds to meet their payment obligations in the future. In addition, the value of U.S. Government securities may be affected by changes in the credit rating of the U.S. Government.U.S. Treasury Strips Risk. Stripped securities do not make periodic interest payments. The value of stripped securities generally fluctuates more in response to interest rate movements than the value of traditional bonds with similar maturity and credit quality. U.S. Treasury strips generally lose value when interest rates rise.
