Expense Narrative [Text Block] oef_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies ("Variable Contract"), which are not reflected in the tables and examples below. If these fees or expenses were included in the table, the Fund's expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract.

Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example does not reflect expenses and charges which are, or may be, imposed under your Variable Contract. If the example were to reflect the deduction of such charges, the costs shown would be greater. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The example reflects the Fund's contractual fee waivers and reimbursement obligations only for the term of the fee waivers and reimbursement obligations. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in the annual fund operating expenses or in the example above, affect the Fund's performance. During the period September 12, 2025 through December 31, 2025, the Fund's portfolio turnover rate was 24% of the average value of its portfolio.

Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

The Fund invests, under normal circumstances, at least 80% of its net assets (plus borrowings for investment purposes) in U.S. listed small capitalization companies and in derivatives that have economic characteristics similar to such securities. The Fund defines small capitalization companies as those companies included in the Russell 2000 Index or within the capitalization range of the Russell 2000 Index at the time of purchase. Equity

securities in which the Fund invests include common stocks and preferred stocks. The Fund also invests in derivatives that are equity equivalent securities or instruments whose values are based on common stocks (i.e., convertible securities, rights, warrants or options (stock or stock index), futures contracts (stock or stock index), and index swaps). The Fund's investments in derivative instruments and other investments which provide exposure to the investment focus indicated in the fund's 80% policy or provide exposure to one or more market risk factors associated with the investment focus indicated in the fund's name, are included in the fund's 80% policy.

The Fund, from time to time, may invest a significant portion of its total assets in securities of companies in a particular sector or particular sectors. As of the date of this Prospectus, the Fund expects to invest a significant portion of its assets in securities of companies in the financials and industrials sectors. The Fund may also invest a portion of its assets in real estate investment trusts ("REITs"), which are companies that own and/or manage properties.

The Adviser has engaged Franklin Advisers, Inc. ("FT") to provide the day-to-day management of the Fund's portfolio pursuant to a multi-style and multi-manager approach and investment guidelines provided by the Adviser. The Fund seeks to achieve its investment objective by allocating its assets among a number of different investment strategies (or "sleeves"), each of which is advised by FT or by FT and a non-discretionary sub-adviser affiliated with FT that provides the Adviser and FT with investment recommendations in the form of a model portfolio, which FT utilizes to purchase and sell securities for the Fund. The sub-advisers utilize different investment strategies in providing investment recommendations for their respective sleeve, act independently from one another, and use their own methodologies for selecting investments. Non-discretionary sub-advisers may employ a fundamental investment approach, a quantitative investment approach, or a combination of both. The Fund's use of such model portfolios and the allocation of Fund assets may change at any time. FT also manages the Fund's cash balances and may manage portions of the Fund during transitions between sub-adviser strategies.

Risk [Text Block] oef_RiskTextBlock

•  Equity Securities Risk. The value of equity securities will rise and fall in response to the activities of the company that issued them, general market conditions and/or economic conditions.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Preferred Stock Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Preferred Stock Risk. Preferred stock represents an equity or ownership interest in an issuer that pays dividends at a specified rate and that has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Small Capitalization Companies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Small Capitalization Companies Risk. 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. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the Fund's ability to purchase or sell these securities.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Active Management Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Active Management Risk. Despite strategies designed to achieve the Fund's investment objective, the value of investments will change with market conditions, and so will the value of any investment in the Fund and you could lose money. The securities selected for the portfolio may not perform as expected. Additionally, securities selected may cause the Fund to underperform relative to other funds with similar investment objectives and strategies. There is no guarantee that the Fund's advisers will effectively assess the Fund's portfolio characteristics, and it is possible that its judgments regarding the Fund's exposures may prove incorrect. In addition, actions taken to manage Fund characteristics, including risk, may be ineffective and/or cause the Fund to underperform.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Multi-Manager Approach Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Multi-Manager Approach Risk. While the investment styles employed by the sub-advisers are intended to be complementary, they may not in fact be complementary. A multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Fundamental Investing Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Fundamental Investing Risk. A fundamental investment approach uses research and analysis of a variety of factors to create a forecast of company results, which is used to select securities. The process may result in an evaluation of a security's value that may be incorrect or, if correct, may not be reflected by the market. Security or instrument selection using a fundamental investment approach may also cause the Fund to

underperform other funds with similar investment objectives and investment strategies even in a rising market.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Quantitative Investing Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Quantitative Investing Risk. Quantitative inputs and models use historical company, economic and/or industry data to evaluate prospective investments or to generate forecasts which could result in incorrect assessments of the specific portfolio characteristics or ineffective adjustments to the Fund's exposures. Securities selected using quantitative analysis may perform differently than analysis of their historical trends would suggest. Inputs or models may be flawed or not work as anticipated and may cause the Fund to underperform other funds with similar investment objectives and strategies.

•  REITs Risk. REITs may be affected by changes in the value of the underlying properties owned by the REITs and by the quality of tenants' credit.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Financial Markets Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Financial Markets Risk. Global economies and financial markets are becoming increasingly interconnected and conditions (including volatility and instability) and events (including natural disasters, pandemics, and epidemics) in one country, region or financial market may adversely impact issuers in a different country, region, or financial market. In addition, governmental and quasi-governmental organizations have taken a number of unprecedented actions designed to support the markets. Such events and conditions may adversely affect the value of the Fund's securities, result in greater market or liquidity risk or cause difficulty valuing the Fund's portfolio instruments or achieving the Fund's objective.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Financials Sector Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial sector, including with respect to U.S. and foreign banks, broker-dealers, insurance companies, finance companies (e.g., automobile finance) and related asset-backed securities. These developments may affect the value of the Fund's investments more than if the Fund were not invested to such a degree in this sector. Companies in the financials sector may be particularly susceptible to factors such as interest rate, fiscal, regulatory, and monetary policy changes.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Industrials Sector Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Industrials Sector Risk. Industrials companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrials sector, are cyclical and have occasional sharp price movements, which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Derivatives Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Derivatives Risk. Investments in a derivative instrument could lose more than the initial amount invested. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities. The use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in equity or fixed income securities, currencies, or other instruments. Derivatives are generally subject to a number of risks such as leveraging risk, liquidity risk (the risk that the investment cannot be sold quickly), market risk, credit risk, default risk, counterparty risk (the risk that the other party in an agreement will fail to perform its obligations), management risk, operational risk, and legal risk. Certain of these risks do not apply to derivative instruments entered into for hedging or cash equitization, certain cleared derivative instruments, and written options contracts. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative instrument may not correlate exactly with the change in the value of the underlying asset, rate, or index.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Non-Discretionary Implementation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Non-Discretionary Implementation Risk. With respect to the portion of the Fund that is managed pursuant to model portfolios provided by non-discretionary sub-advisers, it is expected that trades will be effected on a periodic basis and therefore less frequently than would typically be the case if discretionary sub-advisers were employed. Given that values of investments change with market conditions, this could cause the Fund's return to be lower than if the Fund employed discretionary sub-advisers with respect to that portion of its portfolio.

Venerable US Small Cap Fund | Venerable US Small Cap Fund | Impact of Large Redemptions (Including Possible Fund Liquidation) Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

•  Impact of Large Redemptions (Including Possible Fund Liquidation) Risk. The Fund may be used as an investment by certain funds of funds and may have a large percentage of its shares owned by such funds. Large redemption activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions. Large redemptions may also result in increased expense ratios, higher levels of realized capital gains or losses with respect to the Fund's portfolio securities, higher Fund cash levels, higher brokerage commissions and other transaction costs, among other negative consequences such as reduced liquidity in the Fund's portfolio. As a result, large redemption activity could adversely affect the Fund's ability to conduct its investment program which, in turn, could adversely impact the Fund's performance or may result in the Fund no longer remaining at an economically viable size, in which case the Fund may cease operations.

[2] Until September 12, 2027, Venerable Investment Advisers, LLC (the "Adviser"), the distributor, and certain financial intermediaries have contractually agreed to waive all or a portion of fees (including management fee, administrative services fee, and/or distribution and/or service fee (12b-1 Fee), as applicable) and/or reimburse other operating expenses to the extent necessary to limit total annual operating expenses (excluding interest expenses, short sale expenses, taxes, brokerage commissions, and extraordinary expenses such as litigation expenses) to 0.85% for Class V shares and 1.00% for Class I shares. Termination or modification of these obligations prior to September 12, 2027, requires approval by the Fund's Board of Trustees (the "Board"). To the extent these obligations terminate or are modified, the Fund's total annual operating expenses may increase.
