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 29% 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 intends, under normal market conditions, to invest over 80% of its investable assets in securities included in the S&P Composite 1500 Index (the “Index”) in approximately the same proportions as those of the Index. The Fund is not sponsored by or affiliated with S&P Global Ratings (“S&P”). 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.As of August 31, 2022, the companies included in the Index have market capitalizations ranging from $172 million to $2.5 trillion. The principal type of equity and equity-related securities in which the Fund invests is common stock. In addition to common stocks, the Fund may invest in a combination of cash-equivalent instruments and stock index futures, with the amount committed at any time as initial margin on open futures positions not to exceed 5% of the Fund’s total assets, and exchange-traded funds (“ETFs”) which replicate the Index up to a maximum of 5% of the total assets of the Fund at time of purchase.Replication and Sampling Methods. The Fund seeks to replicate the Index to the extent possible, taking into account asset levels, capital flows and trade size, by investing over 80% of its investable assets in the securities that make up the Index, holding each security in approximately the same proportion as its weighting in the Index. Where it may not be possible or practicable to purchase all of the securities of the Index, the subadviser may use a sampling strategy based on market capitalization and industry weightings. The subadviser may also use stock index futures and/or ETFs to achieve the investment objective. The relative portfolio holdings of the Fund at any time may not be precisely identical to the proportions of holdings of the Index.Although the Fund invests over 80% of its investable assets in securities that comprise the Index, the Fund may at times hold securities that are either to be added to or have been removed from the Index. When a security is removed from the Index, the Fund will sell it within a reasonable time. In addition, the Fund's holdings may change for other reasons, such as when the Fund receives securities of companies spun off from companies in the Index.The subadviser will try to minimize the difference between the investment results of the Fund and those of the Index. Tracking of the Index will be monitored regularly. In addition to potential tracking differences, brokerage, transaction costs and other Fund expenses will cause the Fund's return to be lower than the return of the Index.Although index funds, by their nature, tend to be tax-efficient vehicles, the Fund is managed without regard to tax consequences. As an index fund, the Fund is not actively managed by portfolio managers who buy and sell securities based on research and analysis.
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.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.Equity and Equity-Related Securities Risk. Equity and equity-related securities may be subject to changes in value, and their values may be more volatile than those of other asset classes. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.Exchange-Traded Funds (“ETFs”) Risk. Investing in securities issued by ETFs involves risks similar to those of investing directly in the securities and other assets held by the ETF. Unlike shares of typical mutual funds, shares of ETFs are generally traded on an exchange throughout a trading day and bought and sold based on market values and not at net asset value. For this reason, shares could trade at either a premium or discount to net asset value, which may be substantial during periods of market stress. The trading price of an index-based ETF is expected to (but may not) closely track the net asset value of the ETF, and the Fund will generally gain or lose value consistent with the performance of the ETF’s portfolio securities. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs. In addition, the Fund will indirectly bear its pro rata share of the fees and expenses incurred by an ETF (including ETFs managed by the Manager or the subadviser(s)) in which it invests, including advisory fees (to the extent not offset by the Manager through waivers). These expenses are in addition to the advisory and other expenses that the Fund bears directly in connection with its own operations. An index-based ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investments in ETFs are subject to the risk that the listing exchange may halt trading of an ETF’s shares, in which case the Fund would be unable to sell its ETF shares unless and until trading is resumed.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.Index Investment Approach Risk. Since the Fund is passively managed, assets are not allocated from one stock or group of stocks to another based on their prospects, or from stocks into bonds or cash equivalents in an attempt to cushion the impact of a market decline. As a result, the Fund’s performance may be less favorable than that of a portfolio using an active investment strategy. There is no guarantee that the Fund's investment results will have a high degree of correlation to those of the Index. The Fund’s expenses, changes in securities markets, changes in the composition of the Index, errors in index provider data, and the timing of purchases and redemptions of Fund shares, among other things, may affect the correlation between Fund and Index performance. The Fund may not perform as well as other investments if, among other things, the Index declines or performs poorly relative to other related indexes or individual securities or the securities issued by companies that comprise the Index fall out of favor with investors.Large Capitalization Company Risk. Companies with large market capitalizations go in and out of favor based on market and economic conditions. Larger companies tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Fund's value may not rise or fall as much as the value of funds that emphasize companies with smaller market capitalizations.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.Small and Medium Capitalization Risk. Small and medium capitalization companies usually offer a smaller range of products and services than larger companies. Smaller companies may also have limited financial resources and may lack management expertise. As a result, their prices may fluctuate more than the stocks of larger, more established companies. Historically, small and mid-cap companies have sometimes gone through extended periods when they did not perform as well as larger companies. Small and mid-capitalization companies generally are less liquid than larger companies, which may make such investments more difficult to sell at the time and price that the Fund would like.Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences, transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of distributions, tax gains or losses, changes to the Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.
