Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Portfolio 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. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 132% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock Under normal circumstances, the Portfolio invests at least 80% of its net assets, plus any borrowings for investment purposes, in securities of real assets and activities related to real assets, and in derivatives and other instruments that have economic characteristics similar to such securities. Real assets are defined broadly by the Portfolio and may include assets that have physical properties, such as infrastructure, real estate, and natural resources, as well as infrastructure-related, real estate-related, and natural resources-related investments as described below. The Portfolio considers an issuer to be an infrastructure-related issuer if it derives at least 50% of its revenue or profits from the ownership or operation of infrastructure assets, which include physical structures, networks and systems of transportation, energy, water and sewage, and communication. Examples of infrastructure assets include transportation assets (such as toll roads, bridges, airports and seaports), utility assets (such as generating stations, gas and electric lines, water and sewer facilities, and communications networks) and social assets (such as hospitals, schools, and subsidized housing). The Portfolio considers an issuer to be a real estate or real estate-related company if at least 50% of its assets, gross income or net profits are attributable to ownership, construction, management or sale of residential, commercial or industrial real estate. These issuers include (i) real estate investment trusts (“REITs”) or other real estate operating companies that (a) own property, (b) make or invest in short-term construction and development mortgage loans, or (c) invest in long-term mortgages or mortgage pools, (ii) issuers whose products and services are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions that issue or service mortgages, and (iii) issuers included in a real estate or real estate-related industry based on any one or more third-party providers, such as the S&P Global Industry Classification Standard (GICS), the North American Industry Classification System (NAICS) or the Bloomberg Industry Classification System (BICS). The Portfolio invests primarily in equity securities (including common and preferred stock, and convertible securities) of domestic and foreign issuers. The Portfolio may invest in master limited partnerships (“MLPs”), including MLPs that are not taxed as regular corporations for U.S. federal income tax purposes. The MLPs in which the Portfolio may invest are publicly traded partnerships or limited liability companies engaged in, among other things, the transportation, storage, processing, refining, marketing, exploration, production and mining of minerals and natural resources. The Portfolio also may invest in debt securities of domestic and foreign issuers. The Portfolio may have significant exposure to natural resources through investments in MLPs or other issuers whose business activities are related to natural resource assets. The Portfolio may invest up to 10% of its net assets in non-investment grade debt securities (commonly known as “junk bonds”). Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries (one of which may be the United States), and at least 40%, unless market conditions are not deemed favorable, in which case at least 30%, of the Portfolio’s net assets will provide exposure to investments that are economically tied to countries other than the United States. An issuer will be considered to be economically tied to a country other than the United States if it is domiciled, has its principal office, derives a significant portion of its revenues from, or primarily trades in a market located outside of the United States and/or its “country of risk” as determined by a third party service provider such as Bloomberg is outside the United States. The Portfolio may invest up to 20% of its net assets in securities of issuers located in emerging markets countries (that is, those that are in the early stages of their industrial cycles). The Portfolio may invest in securities of issuers of all capitalization sizes, including small- and mid-capitalization issuers. Real asset companies tend to have smaller asset bases compared with other market sectors, therefore, the Portfolio may hold a significant amount of securities of small and mid-capitalization issuers. The Portfolio considers an issuer to be a small-capitalization issuer if it has a market capitalization, at the time of purchase, no larger than the largest capitalized issuer included in the Russell 2000® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. As of December 31, 2024, the capitalization of companies in the Russell 2000® Index ranged from approximately $9.12 million to $13.19 billion. The Portfolio considers an issuer to be a mid-capitalization issuer if it has a market capitalization, at the time of purchase, within the range of market capitalizations of the largest and smallest capitalized issuers included in the Russell Midcap® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. As of December 31, 2024, the capitalization of companies in the Russell Midcap® Index ranged from approximately $355 million to $175 billion. A company’s “market capitalization” is the value of its outstanding shares. The Portfolio may engage in short sales of securities. The Portfolio may engage in short sales with respect to securities it owns or securities it does not own. Generally, the Portfolio will sell a security short (1) to take advantage of an expected decline in the security price in anticipation of purchasing the same security at a later date at a lower price, or (2) to protect a profit in a security that it owns. The Portfolio will not sell a security short if, as a result of such short sale, the aggregate market value of all securities sold short exceeds 10% of the Portfolio’s net assets. The Portfolio can invest in derivative instruments, including forward foreign currency contracts. The Portfolio can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated, if deemed appropriate by the Sub-Adviser; however, the Portfolio has not historically done so. The Portfolio’s investments in derivatives may be deemed to involve the use of leverage because the Portfolio is not required to invest the full market value of the contract upon entering into the contract but participates in gains and losses on the full contract price. The use of derivatives also may be deemed to involve the use of leverage because the heightened price sensitivity of some derivatives to market changes may magnify the Portfolio’s gain or loss. It is not expected, however, that the Portfolio will be leveraged by borrowing money for investment purposes. When constructing the portfolio, the Sub-Adviser uses a fundamentals-driven investment process, including an evaluation of factors such as market cycle analysis, asset evaluation and management and structure review to identify securities with characteristics including (i) quality underlying assets, (ii) solid management teams with the ability to effectively manage capital structure decisions and execute their stated strategic plan, and (iii) attractive valuations relative to peer investment alternatives. Each qualified security in the investment universe is analyzed using fundamental analysis and valuation review to identify securities that appear to have relatively favorable long-term prospects and attractive values. Some of the fundamental factors that are considered include: forecasted demand and supply of the markets in which a firm may operate, asset locations, physical attributes, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental attributes are then evaluated on the basis of relative value. Some of the valuation factors that are considered include: cash flow consistency and growth, dividend yield, dividend coverage and growth, and cash flow and assets to price multiples. The Sub-Adviser seeks to limit risk through various controls, such as diversifying the portfolio asset types, sectors and geographic areas as well as by considering the relative liquidity of each security and limiting the size of any one holding. The Sub-Adviser may consider selling a security for several reasons, including when (1) its relative valuation has fallen below desired levels, (2) its risk/return profile has changed significantly, (3) its fundamentals have changed, or (4) a more attractive investment opportunity is identified. The Portfolio will concentrate its investments in the securities of domestic and foreign real estate and real estate-related companies. Such investments will consist primarily of REITs. The Portfolio may engage in active and frequent trading.

EQ Invesco Global Real Assets Portfolio | Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Market Risk The Portfolio is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect Portfolio performance. Securities markets also may experience long periods of decline in value. The value of a security can be more volatile than the market as a whole and can perform differently from the market as a whole. Any issuer of securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by a variety of factors, such as poor management decisions; reduced demand for the issuer’s goods or services; competitive pressures; negative perception in the marketplace; loss of major customers; strategic initiatives such as mergers or acquisitions and the market response to any such initiatives; and the historical and prospective earnings of the issuer. The value of a security also may decline due to general market conditions, such as real or perceived adverse economic or political conditions, inflation rates and/or investor expectations concerning such rates, changes in interest rates, recessions, or adverse investor sentiment generally. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Even when securities markets perform well, there can be no assurance that the investments held by the Portfolio will increase in value along with the broader market. Changes in the financial condition of (or other event affecting) a single issuer can impact an individual sector or industry, or the securities markets as a whole. The value of a security also may decline due to factors that affect a particular sector or industry, such as tariffs, labor shortages, or increased production costs and competitive conditions within the sector or industry. Geopolitical events, including acts of terrorism, tensions, war or other open conflicts between nations, or political or economic dysfunction within nations that are global economic powers or major oil or other commodities producers, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. World markets, or those in a particular region, may all react in similar fashion to economic, political or other developments. Events such as environmental and natural disasters or other catastrophes, public health crises (such as epidemics and pandemics), social unrest, and cybersecurity incidents, and governments’ reactions (or failure to react) to such events, could cause uncertainty in the markets and may adversely affect the performance of the global economy. Impacts from climate change may include significant risks to global financial assets and economic growth. The extent and duration of such events and resulting market disruptions could be substantial and could magnify the impact of other risks to the Portfolio. The value and liquidity of the Portfolio’s investments may be negatively affected by developments in other countries and regions, whether or not the Portfolio invests in securities of issuers located in or with significant exposure to the countries or regions directly affected. Changes in government or central bank policies, changes in existing laws and regulations, and political, diplomatic and other events within the United States and abroad could cause uncertainty in the markets, may affect investor and consumer confidence, and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. High public debt and deficits in the United States and other countries create ongoing systemic and market risks and policymaking uncertainty and may negatively affect economic conditions and the values of markets, sectors and companies in which the Portfolio invests. In addition, markets and market participants are increasingly reliant on information data systems. Inaccurate data, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large. Furthermore, impacts from the rapidly growing use of artificial intelligence technologies, including by market participants, may include significant risks to global financial markets.
EQ Invesco Global Real Assets Portfolio | Equity Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Equity Risk In general, the values of stocks and other equity securities fluctuate, and sometimes widely fluctuate, in response to changes in a company’s financial condition as well as general market, economic and political conditions and other factors. Stock markets tend to run in cycles, with periods when stock prices generally go up and periods when stock prices generally go down. However, stock markets also can move up and down rapidly and unpredictably. In addition, common stock prices may be particularly sensitive to rising interest rates, which increase borrowing costs and the costs of capital. The Portfolio may experience a significant or complete loss on its investment in an equity security.
EQ Invesco Global Real Assets Portfolio | Real Estate Investing Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Real Estate Investing Risk Real estate-related investments may decline in value as a result of factors affecting the overall real estate industry. Real estate is a cyclical business, highly sensitive to supply and demand and general and local economic conditions and characterized by intense competition and periodic overbuilding. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes, preferences (such as remote work arrangements or online shopping) and values. Losses may occur from, for example, casualty or condemnation, or extended vacancies of properties, and government actions, such as tax law changes, zoning law changes, regulatory limitations on rents, or environmental regulations, also may have a major impact on real estate. The availability of mortgages and changes in interest rates may also affect real estate values. Changing interest rates and credit quality requirements also will affect the cash flow of real estate companies and their ability to meet capital needs or refinance their obligations. In addition, global climate change may have a significant adverse effect on property and security values and may exacerbate the risks of natural disasters. Real estate investment trusts (“REITs”) generally invest directly in real estate (equity REITs), in mortgages secured by interests in real estate (mortgage REITs) or in some combination of the two (hybrid REITs). Investing in REITs exposes investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which REITs are organized and operated. Equity REITs may be affected by changes in the value of the underlying property owned by the REIT, while mortgage REITs may be affected by the quality of any credit extended. Equity and mortgage REITs are also subject to heavy cash flow dependency, defaults by mortgagors and other borrowers, and self-liquidations. Operating REITs requires specialized management skills, and a portfolio that invests in REITs indirectly bears REIT management and administration expenses along with the direct expenses of the portfolio. Individual REITs may own a limited number of properties and may concentrate in a particular region or property type. Domestic REITs also must satisfy specific Internal Revenue Code requirements to qualify for the tax-free pass-through of net investment income and net realized gains distributed to shareholders. Failure to meet these requirements may have adverse consequences on the Portfolio. In addition, even the larger REITs in the industry tend to be small- to medium-sized companies in relation to the equity markets as a whole. Moreover, shares of REITs may trade less frequently and, therefore, are subject to more erratic price movements than securities of larger issuers.
EQ Invesco Global Real Assets Portfolio | Infrastructure-Related Issuers Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Infrastructure-Related Issuers Risk Infrastructure-related companies may be subject to a variety of factors that could adversely affect their business or operations, including high interest costs in connection with capital construction programs, high degrees of leverage, costs associated with governmental, environmental and other regulations, the effects of economic slowdowns, increased competition from other providers of services, uncertainties concerning costs, the level of government spending on infrastructure projects, the effects of natural disasters, and other factors. Infrastructure-related companies may be adversely affected by commodity price volatility, changes in exchange rates, import controls, depletion of resources, technological developments, and labor relations. Any of these factors could result in a material adverse impact on the Portfolio’s holdings and the performance of the Portfolio.
EQ Invesco Global Real Assets Portfolio | Natural Resources Sector Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Natural Resources Sector Risk The profitability of companies in the natural resources sector can be adversely affected by worldwide energy prices and other world events, limits on and the success of exploration projects, and production spending. Companies in the natural resources sector also can be adversely affected by commodity price volatility, changes in exchange rates, interest rates or inflation rates and/or investor expectations concerning such rates, changes in the supply of, or the demand for, natural resources, climate change, imposition of import controls, government regulation and intervention, civil conflict, economic conditions, increased competition, technological developments, and labor relations. In addition, companies in the natural resources sector may be subject to the risks generally associated with extraction of natural resources, such as the risks of mining and oil drilling, and the risks of the hazards associated with natural resources, such as natural or man-made disasters, fire, drought, liability for environmental damage claims, and increased regulatory and environmental costs. Prices of precious metals and of precious metal related securities have historically been very volatile due to various economic, financial, social and political factors and may adversely affect the financial condition of companies involved with precious metals. Any of these factors could result in a material adverse impact on the Portfolio’s holdings and the performance of the Portfolio.
EQ Invesco Global Real Assets Portfolio | Foreign Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Foreign Securities Risk Investments in foreign securities involve risks in addition to those associated with investments in U.S. securities. Foreign markets may be less liquid, more volatile and subject to less government supervision and regulation than U.S. markets, and it may take more time to clear and settle trades involving foreign securities, which could negatively impact the Portfolio’s investments and cause it to lose money. Security values also may be negatively affected by changes in the exchange rates between the U.S. dollar and foreign currencies. Differences between U.S. and foreign legal, political and economic systems, regulatory regimes and market practices, as well as changes in international trading patterns, trade barriers and other protectionist trade policies (including those of the United States), tariffs, governmental instability, acts of terrorism, war or other open conflicts, or other political, diplomatic or economic actions, also may adversely impact security values. Foreign securities are also subject to the risks associated with the potential imposition of economic or other sanctions against a particular foreign country, its nationals, businesses or industries. World markets, or those in a particular region, may all react in similar fashion to economic, political or other developments. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable and make such investments riskier and more volatile. Regardless of where a company is organized or its stock is traded, its performance may be significantly affected by events in regions from which it derives its profits or in which it conducts significant operations.
EQ Invesco Global Real Assets Portfolio | Currency Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Currency RiskInvestments that are denominated in or that provide exposure to foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. Any such decline may erode or reverse any potential gains from an investment in securities denominated in foreign currency or may widen existing loss. In the case of hedging positions, there is the risk that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates may fluctuate significantly over short periods of time.
EQ Invesco Global Real Assets Portfolio | Emerging Markets Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Emerging Markets RiskThe risks associated with investments in emerging market countries often are significant and vary from jurisdiction to jurisdiction and company to company. Investments in emerging market countries are more susceptible to loss than investments in more developed foreign countries and may present market, credit, currency, liquidity, legal, political, technical and other risks different from, or greater than, the risks of investing in more developed foreign countries. Emerging market countries may be more likely to experience rapid and significant adverse developments in their political or economic structures, intervene in financial markets, restrict foreign investments, impose high withholding or other taxes on foreign investments, impose restrictive exchange control regulations, or nationalize or expropriate the assets of private companies, which may have negative impacts on transaction costs, market price, investment returns, and the legal rights and remedies available to the Portfolio. In addition, the securities markets of emerging market countries generally are smaller, less liquid and more volatile than those of more developed foreign countries, and emerging market countries often have less uniformity in regulatory, accounting, auditing and financial reporting requirements or standards, which may impact the availability and quality of information about issuers, and less reliable clearance and settlement, registration and custodial procedures. Emerging market countries also may be subject to high inflation and rapid currency devaluations, and currency-hedging techniques may be unavailable in certain emerging market countries. In addition, some emerging market countries may be heavily dependent on international trade, which can materially affect their securities markets. Securities of issuers traded on foreign exchanges may be suspended. The likelihood of such suspensions may be higher for securities of issuers in emerging market countries than in countries with more developed markets. The Portfolio's investments in China A-shares are subject to trading restrictions, quota limitations and clearing and settlement risks.
EQ Invesco Global Real Assets Portfolio | Geographic Focus Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Geographic Focus RiskTo the extent the Portfolio invests a significant portion of its assets in securities of companies domiciled, or exercising the predominant part of their economic activity, in one country or geographic region, it assumes the risk that economic, political, social and environmental conditions in that particular country or region will have a significant impact on the Portfolio’s investment performance and that the Portfolio’s performance will be more volatile than the performance of more geographically diversified funds. In addition, the risks associated with investing in a narrowly defined geographic area are generally more pronounced with respect to investments in emerging market countries.
EQ Invesco Global Real Assets Portfolio | Interest Rate Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Interest Rate Risk Changes in interest rates may affect the yield, liquidity and value of investments in debt securities or other income-producing securities. Changes in interest rates also may affect the value of other securities. When interest rates rise, the value of the Portfolio’s debt securities generally declines. Conversely, when interest rates decline, the value of the Portfolio’s debt securities generally rises. Typically, the longer the maturity (i.e., the term of a debt security) or duration (i.e., a measure of the sensitivity of a debt security to changes in market interest rates, based on the entire cash flow associated with the security) of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Portfolio’s debt securities to interest rate risk will increase the greater the duration of those securities. Changes in government or central bank monetary policy may have a substantial and immediate impact on interest rates, which could result in losses to the Portfolio.
EQ Invesco Global Real Assets Portfolio | Mid-Cap and Small-Cap Company Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Mid-Cap and Small-Cap Company Risk Mid-cap and small-cap companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies, all of which can negatively affect their value. In general, these risks are greater for small-cap companies than for mid-cap companies.
EQ Invesco Global Real Assets Portfolio | Portfolio Management Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Portfolio Management Risk The Portfolio is subject to the risk that strategies used by an investment manager and its securities selections fail to produce the intended results. An investment manager’s judgments or decisions about the quality, relative yield or value of, or market trends affecting, a particular security or issuer, industry, sector, region or market segment, or about the economy or interest rates, may be incorrect or otherwise may not produce the intended results, which may result in losses to the Portfolio. In addition, many processes used in Portfolio management, including security selection, rely, in whole or in part, on the use of various technologies. The Portfolio may suffer losses if there are imperfections, errors or limitations in the quantitative, analytic or other tools, resources, information and data used, or the analyses employed or relied on, by an investment manager, or if such tools, resources, information or data are used incorrectly, fail to produce the desired results, or otherwise do not work as intended. There can be no assurance that the use of these technologies will result in effective investment decisions for the Portfolio. In addition, the Portfolio could experience losses if an investment manager’s judgments about the risks associated with the Portfolio’s investment program prove to be incorrect.
EQ Invesco Global Real Assets Portfolio | Convertible Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Convertible Securities Risk A convertible security is a form of hybrid security; that is, a security with both debt and equity characteristics. The value of a convertible security fluctuates in relation to changes in interest rates and the credit quality of the issuer and also fluctuates in relation to changes in the price of the underlying common stock. A convertible security may be subject to redemption at the option of the issuer at a price established in the convertible security’s governing instrument, which may be less than the current market price of the security. If a convertible security held by the Portfolio is called for redemption, the Portfolio will be required to permit the issuer to redeem the security, convert it into the underlying common stock, or sell it to a third party. Convertible securities are subject to equity risk, interest rate risk, and credit risk and are often lower-quality securities. Lower quality may lead to greater volatility in the price of a security and may negatively affect a security’s liquidity. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer-specific risks that apply to the underlying common stock.
EQ Invesco Global Real Assets Portfolio | Credit Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Credit Risk The Portfolio is subject to the risk that the issuer or guarantor of a fixed income security, or the counterparty to a transaction, is unable or unwilling, or is perceived as unable or unwilling, to make timely interest or principal payments or otherwise honor its obligations, or defaults completely, which may cause the Portfolio’s holdings to lose value. The downgrade of a security’s credit rating may decrease its value. Lower credit quality also may lead to greater volatility in the price of a security and may negatively affect a security’s liquidity. The credit quality of a security can deteriorate suddenly and rapidly. The Portfolio may experience a significant or complete loss on a fixed income security or a transaction.
EQ Invesco Global Real Assets Portfolio | Derivatives Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk The Portfolio’s investments in derivatives may rise or fall in value more rapidly than other investments and may reduce the Portfolio’s returns and increase the volatility of the Portfolio’s net asset value. Investing in derivatives involves investment techniques and risk analyses different from, and risks in some respects greater than, those associated with investing in more traditional investments, such as stocks and bonds. Derivatives may be leveraged such that a small investment can have a significant impact on the Portfolio’s exposure to stock market values, interest rates, or other investments. As a result, a relatively small price movement in a derivatives contract may cause an immediate and substantial loss, and the Portfolio could lose more than the amount it invested. Some derivatives can have the potential for unlimited losses. In addition, it may be difficult or impossible for the Portfolio to purchase or sell certain derivatives in sufficient amounts to achieve the desired level of exposure, or to terminate or offset existing arrangements, which may result in a loss or may be costly to the Portfolio. Some derivatives are more sensitive to market price fluctuations and to interest rate changes than other investments. Derivatives may not behave as anticipated by the Portfolio, and derivatives strategies that are successful under certain market conditions may be less successful or unsuccessful under other market conditions. The Portfolio also may be exposed to losses if the counterparty in the transaction is unable or unwilling to fulfill its contractual obligation. In certain cases, the Portfolio may be hindered or delayed in exercising remedies against or closing out derivatives with a counterparty, resulting in additional losses. Derivatives also may be subject to the risk of mispricing or improper valuation, and valuation may be more difficult in times of market turmoil. Changes to the regulation of derivatives markets and mutual funds’ use of derivatives may impact the Portfolio’s ability to maintain its investments in derivatives, make derivatives more costly, limit their availability, adversely affect their value or performance, or otherwise disrupt markets.

Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Large-Cap Company Risk Larger more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes, which may lead to a decline in their market price. Many larger companies also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.
EQ Invesco Global Real Assets Portfolio | Master Limited Partnership Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Master Limited Partnership Risk Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs are generally considered interest-rate sensitive investments that rely on capital markets to finance capital expenditures and growth opportunities. MLPs that concentrate in a particular industry, such as in the energy or natural resources sectors, or a particular geographic region are subject to risks associated with such industry or region. Investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to vary their portfolios promptly in response to changes in economic or other conditions. MLPs may have limited financial resources, their securities may trade infrequently and in limited volume, and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly based companies, and may be difficult to value. Distributions from an MLP may consist in part of a return of the amount originally invested, which would not be taxable to the extent the distributions do not exceed the investor’s adjusted basis in its MLP interest. These reductions in the Portfolio’s adjusted tax basis in the MLP securities will increase the amount of gain (or decrease the amount of loss) recognized by the Portfolio on a subsequent sale of the securities.
EQ Invesco Global Real Assets Portfolio | Non-Investment Grade Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Non-Investment Grade Securities Risk Bonds rated below BBB by Standard & Poor’s Global Ratings or Fitch Ratings, Ltd. or below Baa by Moody’s Investors Service, Inc. (or, if unrated, determined by the investment manager to be of comparable quality) are speculative in nature and are subject to additional risk factors such as increased possibility of default, illiquidity of the security, and changes in value based on changes in interest rates. Non-investment grade bonds, sometimes referred to as “junk bonds,” are usually issued by companies without long track records of sales and earnings, or by those companies with questionable credit strength. The creditworthiness of issuers of non-investment grade debt securities may be more complex to analyze than that of issuers of investment grade debt securities, and reliance on credit ratings may present additional risks.

Risk Return Abstract rr_RiskReturnAbstract

EQ Invesco Global Real Assets Portfolio | Preferred Stock Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Preferred Stock Risk Preferred stock is subject to issuer-specific and market risks applicable generally to equity securities; however, unlike common stock, participation in the growth of an issuer may be limited. Preferred stock also is subject to many of the risks associated with debt securities, including credit and interest rate risk. Unlike interest payments on debt securities, dividends on preferred stock are generally payable at the discretion of the issuer’s board of directors. Preferred shareholders may suffer a loss of value if dividends are not paid. In addition, in the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s debt securities take precedence over the claims of owners of the issuer’s preferred and common stock. For these reasons, preferred stocks are subject to greater credit, interest rate, and liquidation risk than debt securities, and the market prices of preferred stocks are generally more sensitive to actual or perceived changes in the issuer’s financial condition or prospects than are the prices of debt securities.
EQ Invesco Global Real Assets Portfolio | Short Position Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Short Position Risk The Portfolio may engage in short sales and may enter into derivative contracts that have a similar economic effect (e.g., taking a short position in a futures contract). The Portfolio will incur a loss as a result of a short position if the price of the asset sold short increases between the date of the short position sale and the date on which an offsetting position is purchased. Short positions may be considered speculative transactions and involve special risks that could cause or increase losses or reduce gains, including greater reliance on the investment adviser’s ability to accurately anticipate the future value of a security or instrument, higher transaction costs, and imperfect correlation between the actual and desired level of exposure. Short sales present a risk of unlimited loss on an individual security basis, particularly in cases where the Portfolio is unable, for whatever reason, to close out its short position, because the Portfolio may be required to buy the security sold short at a time when the security has appreciated in value, and there is potentially no limit to the amount of such appreciation. In addition, by investing the proceeds received from selling securities short, the Portfolio could be deemed to be employing a form of leverage, in that it amplifies changes in the Portfolio’s net asset value because it increases the Portfolio’s exposure to the market and may increase losses and the volatility of returns. Market or other factors may prevent the Portfolio from closing out a short position at the most desirable time or at a favorable price.
