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 49% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 49.00%
Expenses Deferred Charges [Text Block] rr_ExpensesDeferredChargesTextBlock Investors who purchase $1 million or more of Class A shares and sell these shares within 12 months of purchase are also subject to a contingent deferred sales charge (“CDSC”) of 1.00%, although they are not subject to an initial sales charge.

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 seeks investments whose prices will increase as well as pay the Fund dividends and other income. The Fund normally invests at least 80% of its investable assets in equity and equity-related and investment-grade debt securities of utility companies. The term “investable assets” 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. The Fund concentrates investments in utility companies, based on the Global Industry Classification Standard (“GICS”) Industry classifications, as they may be amended from time to time, which includes electric utilities, gas utilities, water utilities, multi-utilities, independent power and renewable electricity producers, diversified telecommunication services, wireless telecommunication services, and GICS subindustry, oil & gas storage & transportation.The Fund buys equity and equity-related securities, including common stocks; nonconvertible preferred stocks; convertible securities—like bonds, corporate notes and preferred stocks—that can convert into the company's common stock, the cash value of common stock, or some other equity security; American Depositary Receipts (“ADRs”); warrants and rights that can be exercised to obtain stocks; equity securities of real estate investment trusts (“REITs”); investments in various types of business ventures, including partnerships and joint ventures; master limited partnerships (“MLPs”); and similar securities. The Fund invests in companies of any market capitalization.The Fund’s investment in debt securities, including corporate and government bonds, is generally limited to those rated investment-grade by a major rating service (such as BBB or above by S&P Global Ratings (“S&P”) or Baa or above by Moody's Investors Service, Inc. (“Moody's”)) or, if not rated, to those the subadviser believes are of comparable quality.The Fund may invest up to 50% of its investable assets in foreign securities.The Fund participates in the initial public offering (“IPO”) market.The subadviser looks for stocks of companies that it believes will produce both above-average earnings and dividend growth over the long term. In deciding which stocks to buy, the subadviser uses a total return approach. That is, the subadviser seeks to invest in stocks that it believes have the potential to generate stable and increasing cash-flow that can be returned to investors through growing dividends or share repurchases. The subadviser also invests in stocks that it believes are undervalued, given the company’s earnings, cash-flows, or asset values, and may look for catalysts that will help unlock inherent value. A number of conditions can warrant the sale of an existing position, including (1) the stock has reached its price target; (2) subsequent events invalidate the subadviser’s investment thesis; (3) the catalysts it expected to narrow the gap between the stock price and what it believes to be the true worth of the company have passed or no longer exist; or (4) the stock price declines to below what the subadviser had thought to be the reasonable worst-case scenario.The Fund is “non-diversified” for purposes of the Investment Company Act of 1940 (the “1940 Act”), which means that it can invest a greater percentage of its assets in fewer issuers than a “diversified” fund.

Risk [Text Block] rr_RiskTextBlock You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
PGIM Jennison Utility Fund | Risk Not Insured Depository Institution [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
PGIM Jennison Utility Fund | Credit Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
PGIM Jennison Utility Fund | Currency Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Currency Risk. The Fund's net asset value could decline as a result of changes in exchange rates, which could adversely affect the Fund’s investments in currencies, or in securities that trade in, and receive revenues related to, currencies, or in derivatives that provide exposure to currencies. 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.
PGIM Jennison Utility Fund | Economic And Market Events Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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, or otherwise reduce inflation may at times result in unusually high market volatility, which could negatively impact performance. Governmental efforts to curb inflation often have negative effects on the level of economic activity. Relatively reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.
PGIM Jennison Utility Fund | Equity And Equity Related Securities Risks [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
PGIM Jennison Utility Fund | Foreign Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
PGIM Jennison Utility Fund | Geographic Concentration Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Geographic Concentration Risk. The Fund’s performance may be closely tied to the market, economic, political, regulatory or other conditions in the countries or regions in which the Fund invests. This can result in more pronounced risks based upon conditions that impact one or more countries or regions more or less than other countries or regions.
PGIM Jennison Utility Fund | Increase In Expenses Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
PGIM Jennison Utility Fund | Initial Public Offerings Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Initial Public Offerings Risk. The volume of IPOs and the levels at which the newly issued stocks trade in the secondary market are affected by the performance of the stock market overall. If IPOs are brought to the market, availability may be limited and if the Fund desires to acquire shares in such an offering, it may not be able to buy any shares at the offering price, or if it is able to buy shares, it may not be able to buy as many shares at the offering price as it would like. The prices of securities involved in IPOs are often subject to greater and more unpredictable price changes than more established stocks. Such unpredictability can have a dramatic impact on the Fund's performance (higher or lower) and any assumptions by investors based on the affected performance may be unwarranted. In addition, as Fund assets grow, the impact of IPO investments on performance will decline, which could reduce total returns.
PGIM Jennison Utility Fund | Large Shareholder And Large Scale Redemption Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
PGIM Jennison Utility Fund | Management Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Management Risk. Actively managed funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but the subadviser's judgments about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements may be incorrect. Additionally, the investments selected for the Fund may underperform the markets in general, the Fund's benchmark and other funds with similar investment objectives.
PGIM Jennison Utility Fund | Market Capitalization Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Market Capitalization Risk. The Fund may invest in companies of any market capitalization. Generally, the stock prices of small- and mid-cap companies are less stable than the prices of large-cap stocks and may present greater risks. Large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform compared to investments that focus on smaller capitalized companies.
PGIM Jennison Utility Fund | Market Disruption And Geopolitical Risks [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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 Ukraineand the Israel-Hamas war), 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.
PGIM Jennison Utility Fund | Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
PGIM Jennison Utility Fund | Non Diversified Investment Company Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Non-Diversified Investment Company Risk. The Fund is non-diversified for purposes of the 1940 Act. This means that the Fund may invest a greater percentage of its assets in the securities of a single company or other issuer than a diversified fund. Investing in a non-diversified fund involves greater risk than investing in a diversified fund because a loss resulting from the decline in value of any one security may represent a greater portion of the total assets of a non-diversified fund.
PGIM Jennison Utility Fund | Utility Sector Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Utility Sector Risk. The Fund is subject to risks of the utility industry, such as changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest and exchange rate fluctuations, liabilities for environmental damage and changes in the cost of providing specific utility services, due to its concentration in utility securities. The utilities industry is also subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. When interest rates go up, the value of securities issued by utility companies historically has gone down. Although the average dividend yield of utility industry stocks has been higher than those of other companies, the total return of utility securities has historically underperformed those of industrial companies. In most countries and localities, the utility industry is regulated by governmental entities, which can increase costs and delays for new projects and make it difficult to pass increased costs on to consumers. In certain areas, deregulation of utilities has resulted in increased competition and reduced profitability for certain companies, and increased the risk that a particular company will become bankrupt or fail completely. Reduced profitability, as well as new uses for or additional need of funds (such as for expansion, operations or stock buybacks), could result in reduced dividend payout rates for utility companies. In addition, utility companies face the risk of increases in the cost and reduced availability of fuel (such as oil, coal, natural gas or nuclear energy) and potentially high interest costs for borrowing to finance new projects. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies. As a sector fund, the Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance indexes.

[1] Investors who purchase $1 million or more of Class A shares and sell these shares within 12 months of purchase are also subject to a contingent deferred sales charge (“CDSC”) of 1.00%, although they are not subject to an initial sales charge. The CDSC is waived for certain retirement and/or benefit plans.
[2] PGIM Investments LLC (“PGIM Investments”) has contractually agreed, through March 31, 2025, to limit transfer agency, shareholder servicing, sub-transfer agency, and blue sky fees, as applicable, to the extent that such fees cause the Total Annual Fund Operating Expenses to exceed 0.52% of average daily net assets for Class R6 shares. This contractual expense limitation excludes interest, brokerage, taxes (such as income and foreign withholding taxes, stamp duty and deferred tax expenses), acquired fund fees and expenses, extraordinary expenses, and certain other Fund expenses such as dividend and interest expense and broker charges on short sales. Where applicable, PGIM Investments agrees to waive management fees or shared operating expenses on any share class to the same extent that it waives such expenses on any other share class. In addition, Total Annual Fund Operating Expenses for Class R6 shares will not exceed Total Annual Fund Operating Expenses for Class Z shares. Fees and/or expenses waived and/or reimbursed by PGIM Investments for the purpose of preventing the expenses from exceeding a certain expense ratio limit may be recouped by PGIM Investments within the same fiscal year during which such waiver and/or reimbursement is made if such recoupment can be realized without exceeding the expense limit in effect at the time of the recoupment for that fiscal year. This expense limitation may not be terminated prior to March 31, 2025 without the prior approval of the Fund’s Board of Directors.
[3] The distributor of the Fund has contractually agreed to limit its distribution and service (12b-1) fees to 0.50% of the average daily net assets of the Fund’s Class R shares through March 31, 2025. This waiver may not be terminated prior to March 31, 2025 without the prior approval of the Fund’s Board of Directors.
[4] Class C shares are sold with a CDSC of 1.00% on sales made within 12 months of purchase.
[5] Direct Transfer Agent Accounts holding under $10,000 of Class Z shares are subject to the $15 fee.
[6] Since Inception returns for the Index are measured from the closest month-end to the inception date for Class R6 shares.
