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 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 most recent fiscal year, the Fund's portfolio turnover rate was 11% of the average value of its portfolio.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in securities of small- and mid-capitalization companies. For the Fund, small-capitalization companies generally are companies with a market capitalization less than $3 billion at the time of investment, and mid-capitalization companies generally are companies with a market capitalization between $3 billion and $12 billion at the time of investment. The Fund invests primarily in common stocks, but it also may invest in other securities that GAMCO Asset Management Inc. (“GAMCO” or the “Sub-Adviser”) believes provide opportunities for capital growth, such as preferred stocks and warrants. The Fund also may invest up to 20% of its net assets in foreign securities. GAMCO utilizes a value-oriented investment style that emphasizes companies deemed to be currently underpriced according to certain financial measurements, which may include price-to-earnings and price-to-book ratios. In choosing investments, the Sub-Adviser utilizes a process of fundamental analysis that involves researching and evaluating individual companies for potential investment by the Fund. The Sub-Adviser uses a proprietary research technique to determine which stocks have a market price that is less than the “private market value” of a company. The “private market value” of a company is the value that the Sub-Adviser believes informed investors would be willing to pay to acquire the entire company. This approach will often lead the Fund to focus on “strong companies” in out-of-favor sectors or out-of-favor companies exhibiting a catalyst for change. The Sub-Adviser may sell a security for a variety of reasons, such as because, in the Sub-Adviser’s view, it becomes overvalued or shows deteriorating fundamentals, or to invest in a company believed by the Sub-Adviser to offer superior investment opportunities.

Risk [Text Block]	rr_RiskTextBlock	An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
1290 GAMCO Small-Mid Cap Value Fund | Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Risk —  The Fund 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 Fund 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 Fund 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 important 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 Fund. The value and liquidity of the Fund’s investments may be negatively affected by developments in other countries and regions, whether or not the Fund 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 Fund 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.
1290 GAMCO Small-Mid Cap Value Fund | 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 Fund may experience a significant or complete loss on its investment in an equity security.
1290 GAMCO Small-Mid Cap Value Fund | 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.
1290 GAMCO Small-Mid Cap Value Fund | Investment Style Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Investment Style Risk —  The Fund may use a particular style or set of styles — in this case, a “value” style — to select investments. A particular style may be out of favor or may not produce the best results over short or longer time periods. Value stocks are subject to the risks that, notwithstanding that a stock is selling at a discount to its perceived true worth, the stock’s full value may never be fully recognized or realized by the market, or its price may go down. In addition, there is the risk that a stock judged to be undervalued may actually have been appropriately priced at the time of investment.
1290 GAMCO Small-Mid Cap Value Fund | Sector Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Sector Risk —  From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political, regulatory or other events.
1290 GAMCO Small-Mid Cap Value Fund | Industrials Sector Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Industrials Sector Risk —  The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand changes related to their specific products or services and industrials sector products in general. Companies in the industrials sector may also be adversely affected by global events; changes in government regulations, economic conditions, and exchange rates; liability for environmental damage and product liability claims; changes or trends in commodity prices; and government spending policies. Any of these factors could result in a material adverse impact on the Fund’s holdings and the performance of the Fund.
1290 GAMCO Small-Mid Cap Value Fund | Portfolio Management Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Portfolio Management Risk —  The Fund 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 Fund. In addition, many processes used in Fund management, including security selection, rely, in whole or in part, on the use of various technologies. The Fund 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 Fund. In addition, the Fund could experience losses if an investment manager’s judgments about the risks associated with the Fund’s investment program prove to be incorrect.
1290 GAMCO Small-Mid Cap Value Fund | 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 Fund’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 important 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.
1290 GAMCO Small-Mid Cap Value Fund | Currency Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Currency Risk —  Investments 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.
1290 GAMCO Small-Mid Cap Value Fund | Large Transaction Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Large Transaction Risk —  A significant percentage of the Fund’s shares may be owned or controlled by the Adviser and its affiliates, other funds advised by the Adviser or its affiliates (including funds of funds), or other large shareholders, including financial intermediaries that may include the Fund in their investment models. Accordingly, the Fund is subject to the potential for large-scale, relative to its asset size, inflows and outflows as a result of purchases and redemptions of its shares by such shareholders. These inflows and outflows may accelerate the realization of taxable income to shareholders if such sales of investments result in gains. These inflows and outflows also could negatively affect the Fund’s net asset value and performance.
1290 GAMCO Small-Mid Cap Value Fund | 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.

[1] On shares purchased without an initial sales charge and redeemed within 12 months of purchase.

[2] Pursuant to a contract, Equitable Investment Management, LLC (the “Adviser”) has agreed to waive its and its affiliates’ management, administrative and other fees and, if necessary, make payments to the Fund to limit the expenses of the Fund through April 30, 2026 (unless the Board of Trustees consents to an earlier revision or termination of this arrangement) (“Expense Limitation Arrangement”) so that the annual operating expenses (including Acquired Fund Fees and Expenses) of the Fund (exclusive of taxes, interest, brokerage commissions, capitalized expenses (other than offering costs), 12b-1 fees, dividend and interest expenses on securities sold short, and extraordinary expenses not incurred in the ordinary course of the Fund’s business) do not exceed an annual rate of average daily net assets of 0.95% for Class A shares, Class I shares, and Class R shares of the Fund. The Expense Limitation Arrangement may be terminated by the Adviser at any time after April 30, 2026. The Adviser may be reimbursed the amount of any such waivers or payments in the future provided that the waivers or payments are reimbursed within three years of the waivers or payments being recorded and the Fund’s expense ratio, after the reimbursement is taken into account, does not exceed the Fund’s expense cap at the time of the waiver or the Fund’s expense cap at the time of the reimbursement, whichever is lower. The total annual fund operating expense ratios after fee waiver and/or expense reimbursement for Class A shares and Class R shares, as shown in the table, are higher than the Fund’s expense cap because these ratios include 12b-1 fees and certain other expenses, as noted above, that are excluded from the Expense Limitation Arrangement.
