Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock The tables below describe the sales charges, fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and an eligible group of related investors purchase, or agree to purchase in the future, $25,000 or more in shares of the Fund or other funds in the Prudential Investments family of funds. More information about these discounts is available from your financial professional and is explained in Reducing or Waiving Class A's Initial Sales Charge on page 23 of the Fund's Prospectus and in Rights of Accumulation on page 56 of the Fund's Statement of Additional Information (SAI).

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
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 87% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 87.00%
Expense Footnotes [Text Block] rr_ExpenseFootnotesTextBlock ° The distributor of the Fund has contractually agreed through November 30, 2015 to reduce its distribution and service (12b-1) fees for Class A shares to an annual rate of .25% of the average daily net assets of Class A shares and its distribution and service (12b-1) fees for Class R shares to an annual rate of .50% of the average daily net assets of Class R shares. These waivers may not be terminated prior to November 30, 2015. The decision on whether to renew, modify or terminate the waivers is subject to review by the distributor and the Fund’s Board of Trustees.

Expense Example [Heading] rr_ExpenseExampleHeading Example.
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 [Heading] rr_StrategyHeading INVESTMENTS, RISKS AND PERFORMANCE

Principal Investment Strategies.
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund seeks to achieve its investment objective by investing in a well diversified portfolio of equity and equity-related securities. Under normal market conditions, the Fund will invest at least 80% of its investable assets (net assets plus borrowings for investment purposes, if any) in equity and equity-related securities. For purposes of this 80% policy, equity and equity-related securities include (i) common and preferred stock (and securities convertible into, or that the subadviser expects to be exchanged for, common or preferred stock), (ii) exchange-traded funds (ETFs), and (iii) synthetic instruments and derivatives that have economic characteristics that are similar to equity securities, including certain options, futures, swaps, and exchange-traded notes (ETNs) whose interest or principal payments are linked to one or more equity securities or equity indices. The subadviser will evaluate investments across equity market sectors, based on a variety of factors, including but not limited to momentum, valuation, volatility and correlation, and will allocate and periodically rebalance the Fund’s portfolio across the different sectors based on changes in these factors. The subadviser may also use risk mitigation techniques to reduce downside risk. Investment decisions will be determined using a combination of quantitative tools and the judgment of the subadviser's investment professionals.

The Fund may invest in securities of any market capitalization. The Fund may invest up to 20% of its investable assets in debt securities of varying credit quality. The Fund may invest up to 20% of total assets in securities of foreign issuers. The Fund may invest up to 25% of its net assets in derivatives. Although the Fund is not limited in the types of derivatives it can use, the Fund currently expects that its principal investments in derivative instruments will include investments in futures contracts, but the Fund may also invest in options and swaps.

While we make every effort to achieve the Fund’s objective, we can’t guarantee success.

The Fund will provide 60 days’ prior written notice to shareholders of a change in its non-fundamental policy of investing at least 80% of its investable assets in equity and equity-related securities. The Fund may actively and frequently trade its portfolio securities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund.
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock All investments have risks to some degree. Loss of money is a risk of investing in the Fund. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.

Market Events. The global financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities and unprecedented volatility in the markets. In response to the crisis, the US government and the Federal Reserve, as well as certain foreign governments and their central banks, have taken steps to support financial markets, including keeping interest rates low. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities.

This environment could make identifying investment risks and opportunities especially difficult for the subadviser, and whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected. In addition, policy and legislative changes in the United States and other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.

Risk of Increase in Expenses. 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.

Equity and Equity-Related Securities Risks. The value of a particular security could go down and you could lose money. 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. The Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

The Fund may invest in companies that reinvest their earnings rather than distribute them to shareholders. To the extent the Fund does invest in such companies, the Fund is not likely to receive significant dividend income on its portfolio securities.

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.

Sector Focused Investing Risk. The risk that events negatively affecting an industry or market sector in which the Fund focuses its investments will cause the value of the Fund’s shares to decrease, perhaps significantly.

Derivatives Risk. The Fund may engage in a variety of transactions using “derivatives,” such as futures, options, forwards and swaps. Derivatives are financial instruments whose value depends upon, or is derived from, the value of something else, such as one or more underlying investments, indexes or currencies. Derivatives may be traded on organized exchanges, or in individually negotiated transactions with other parties (these are known as “over-the-counter” derivatives). The Fund will use derivatives both for hedging purposes (to seek to reduce risk) and for non-hedging purposes (to seek to increase return consistent with the Fund's investment objective). Although the Fund has the flexibility to make use of derivatives, it may choose not to for a variety of reasons, even under very volatile market conditions.

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 investment 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” 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 at any time. 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.

Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation of derivatives may make them more costly, may limit their availability, or may otherwise adversely affect their value or performance.

Management Risk. Actively managed mutual funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these techniques will produce the desired results. Additionally, the securities selected by the subadviser may underperform the markets in general, the Fund’s benchmark and other mutual funds with similar investment objectives.

Portfolio Turnover Risk. The length of time the Fund has held a particular security is not generally a consideration in investment decisions. Under certain market conditions, the Fund’s turnover rate may be higher than that of other mutual funds. Portfolio turnover generally involves some expense to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestment in other securities. These transactions may result in realization of taxable capital gains. The trading costs and tax effects associated with portfolio turnover may adversely affect the Fund’s investment performance.

Market Risk. The securities markets are 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.
