Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund's performance. During the most recent fiscal year, the Predecessor Fund's portfolio turnover rate was 90% of the average value of its portfolio.

Example.
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

•  Your investment has a 5% return each year

•  The Fund's operating expenses remain the same (except that the examples reflect the expense limitation arrangements for only the first year)

•  You reinvest all dividends and distributions

•  You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, for every $10,000 invested, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

Strategy [Heading] rr_StrategyHeading
PRINCIPAL INVESTMENT STRATEGY.
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund normally invests at least 80% of its total assets in a diversified portfolio of equity securities, or derivative investments that provide exposure to equity securities, of companies located outside of the United States that the Fund's sub-advisers, Schroder Investment Management North America Inc. ("SIMNA") and Schroder Investment Management North America Limited ("SIMNA Ltd.," together with SIMNA, the "Sub-Advisers"), consider to offer attractive valuations. The Fund invests in a variety of countries throughout the world including emerging market countries and may, from time to time, invest more than 25% of its assets in any one country or group of countries. The Fund may invest in companies of any market capitalization. The Sub-Advisers apply a proprietary quantitative investment analysis that seeks to capture the high returns historically available from value stocks. The Sub-Advisers do not consider benchmark weights when they construct the Fund's portfolio. The Sub-Advisers believe that indices weighted by market-capitalization reflect a natural bias toward expensive stocks and geographic regions, and that, by contrast, a "bottom-up" approach to portfolio construction, not constrained by reference to a specific benchmark or index, may uncover less expensive stocks offering better investment value. The Sub-Advisers seek to select relatively inexpensive stocks of issuers located anywhere in the world based on an evaluation of a number of valuation metrics including: dividends, cash-flow, earnings, sales and asset-based measures. There is also a focus on high quality companies within this universe defined using metrics including: profitability, stability, financial strength, and management quality. Geographic and sector allocations are principally the result of this selection. The Sub-Advisers may also consider certain environmental, social and governance criteria. The Fund may invest in common and preferred stocks, convertible securities and warrants. The Fund may also invest in real estate investment trusts ("REITs"), trusts, closed-end funds, or exchange-traded funds. The Fund may purchase or sell futures contracts and options and enter into total return swaps, in order to gain long or short exposure to particular securities or markets in connection with hedging transactions or otherwise to increase total return. The Fund may from time to time enter into other transactions involving derivatives, including over-the-counter transactions, if the Sub-Advisers consider it appropriate. The Fund may, but is not required to, enter into foreign currency exchange transactions, for risk management or hedging purposes.
Risk [Heading] rr_RiskHeading
PRINCIPAL RISKS.
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective. For more information regarding risks and investment matters, please see "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.

Market Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to the activities and financial prospects of individual companies or to general market and economic movements and trends, including adverse changes to credit markets.

Foreign Investments Risk – Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions, may affect the value of the Fund's investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund's foreign investments.

Emerging Markets Risk – The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Currency Risk – The risk that the value of the Fund's investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer's local currency.

Equity Risk – The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Quantitative Investing Risk – The value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance. This may be as a result of the factors used in building the quantitative analytical framework, the weights placed on each factor, the accuracy of historical data supplied by third parties, and changing sources of market returns.

Mid Cap and Small Cap Securities Risk – Investments in small capitalization and mid capitalization companies involve greater risks than investments in larger, more established companies. Many of these companies are young and have limited operating or business history. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks, include the risks of bankruptcy.

Real Estate Related Securities Risks – In addition to general market risk, the main risk of real estate related securities is that the value of the underlying real estate may go down due, among other factors, to the strength of the general and local economies, the amount of new construction in a particular area, the laws and regulations affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgages and changes in interest rates may also affect real estate values. The real estate industry is particularly sensitive to economic downturns. If the Fund's real estate related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type.

Active Trading Risk – Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

Value Investing Style Risk – Using a value investing style to select investments involves special risks, particularly if it is used as part of a "contrarian" approach to evaluating issuers. Overlooked or otherwise undervalued securities entail a significant risk of never attaining their potential value. Also, the value investing style may over time go in and out of favor. At times when the value investing style is out of favor, the Fund may underperform other equity funds that use different investing styles.

 

Investment Strategy Risk – The risk that, if the Sub-Advisers' investment strategy does not perform as expected, the Fund could underperform its peers or lose money. There is no guarantee that the Fund's investment objective will be achieved.

Large Shareholder Transaction Risk – The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's net asset value ("NAV") and liquidity. Similarly, large Fund share purchases may adversely affect a Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks, which are discussed in "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.

PAST PERFORMANCE.
Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The performance information below indicates the risks of investing in the Fund. The performance information shown below for Class A and Class I shares reflects the historical performance, fees and expenses of the then-existing Advisor and Investor Class shares, respectively, of the Schroder International Multi-Cap Value Fund (the "Predecessor Fund"). Performance information for Class C, Class R3, Class R4, Class R5, and Class Y shares reflects the performance, fees and expenses of the Predecessor Fund's Investor Class shares. The Fund has the same investment objective as that of its Predecessor Fund, and SIMNA and SIMNA Ltd. served as the investment manager and sub-adviser, respectively, to the Predecessor Fund. Keep in mind that past performance does not indicate future results. Updated performance information is available at www.hartfordfunds.com.

The returns:

•  Assume reinvestment of all dividends and distributions

•  Would be different if the Fund's fees and expenses were reflected.

Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund's performance. During the most recent fiscal year, the Predecessor Fund's portfolio turnover rate was 90% of the average value of its portfolio.

Example.
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

•  Your investment has a 5% return each year

•  The Fund's operating expenses remain the same (except that the examples reflect the expense limitation arrangements for only the first year)

•  You reinvest all dividends and distributions

•  You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, for every $10,000 invested, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

Strategy [Heading] rr_StrategyHeading
PRINCIPAL INVESTMENT STRATEGY.
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund normally invests at least 80% of its total assets in a diversified portfolio of equity securities, or derivative investments that provide exposure to equity securities, of companies located outside of the United States that the Fund's sub-advisers, Schroder Investment Management North America Inc. ("SIMNA") and Schroder Investment Management North America Limited ("SIMNA Ltd.," together with SIMNA, the "Sub-Advisers"), consider to offer attractive valuations. The Fund invests in a variety of countries throughout the world including emerging market countries and may, from time to time, invest more than 25% of its assets in any one country or group of countries. The Fund may invest in companies of any market capitalization. The Sub-Advisers apply a proprietary quantitative investment analysis that seeks to capture the high returns historically available from value stocks. The Sub-Advisers do not consider benchmark weights when they construct the Fund's portfolio. The Sub-Advisers believe that indices weighted by market-capitalization reflect a natural bias toward expensive stocks and geographic regions, and that, by contrast, a "bottom-up" approach to portfolio construction, not constrained by reference to a specific benchmark or index, may uncover less expensive stocks offering better investment value. The Sub-Advisers seek to select relatively inexpensive stocks of issuers located anywhere in the world based on an evaluation of a number of valuation metrics including: dividends, cash-flow, earnings, sales and asset-based measures. There is also a focus on high quality companies within this universe defined using metrics including: profitability, stability, financial strength, and management quality. Geographic and sector allocations are principally the result of this selection. The Sub-Advisers may also consider certain environmental, social and governance criteria. The Fund may invest in common and preferred stocks, convertible securities and warrants. The Fund may also invest in real estate investment trusts ("REITs"), trusts, closed-end funds, or exchange-traded funds. The Fund may purchase or sell futures contracts and options and enter into total return swaps, in order to gain long or short exposure to particular securities or markets in connection with hedging transactions or otherwise to increase total return. The Fund may from time to time enter into other transactions involving derivatives, including over-the-counter transactions, if the Sub-Advisers consider it appropriate. The Fund may, but is not required to, enter into foreign currency exchange transactions, for risk management or hedging purposes.
Risk [Heading] rr_RiskHeading
PRINCIPAL RISKS.
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective. For more information regarding risks and investment matters, please see "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.

Market Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to the activities and financial prospects of individual companies or to general market and economic movements and trends, including adverse changes to credit markets.

Foreign Investments Risk – Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions, may affect the value of the Fund's investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund's foreign investments.

Emerging Markets Risk – The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Currency Risk – The risk that the value of the Fund's investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer's local currency.

 

Equity Risk – The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Quantitative Investing Risk – The value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance. This may be as a result of the factors used in building the quantitative analytical framework, the weights placed on each factor, the accuracy of historical data supplied by third parties, and changing sources of market returns.

Mid Cap and Small Cap Securities Risk – Investments in small capitalization and mid capitalization companies involve greater risks than investments in larger, more established companies. Many of these companies are young and have limited operating or business history. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks, include the risks of bankruptcy.

Real Estate Related Securities Risks – In addition to general market risk, the main risk of real estate related securities is that the value of the underlying real estate may go down due, among other factors, to the strength of the general and local economies, the amount of new construction in a particular area, the laws and regulations affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgages and changes in interest rates may also affect real estate values. The real estate industry is particularly sensitive to economic downturns. If the Fund's real estate related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type.

Active Trading Risk – Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

Value Investing Style Risk – Using a value investing style to select investments involves special risks, particularly if it is used as part of a "contrarian" approach to evaluating issuers. Overlooked or otherwise undervalued securities entail a significant risk of never attaining their potential value. Also, the value investing style may over time go in and out of favor. At times when the value investing style is out of favor, the Fund may underperform other equity funds that use different investing styles.

Investment Strategy Risk – The risk that, if the Sub-Advisers' investment strategy does not perform as expected, the Fund could underperform its peers or lose money. There is no guarantee that the Fund's investment objective will be achieved.

Large Shareholder Transaction Risk – The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's net asset value ("NAV") and liquidity. Similarly, large Fund share purchases may adversely affect a Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks, which are discussed in "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.
