A higher portfolio turnover rate may indicate higher transactions costs and may mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 89% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in common stocks of mid-sized U.S. companies. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy. The Fund normally invests in companies that the sub-adviser (“Sub-Adviser”) believes have above average prospects for growth. For this Fund, mid-sized companies are those companies with market capitalizations that fall within the range of companies in the Russell Midcap® Growth Index at the time of purchase. Capitalization of companies in the Russell Midcap® Growth Index will change with market conditions. The market capitalization of companies in the Russell Midcap® Growth Index as of June 29, 2012, ranged from $1.1 billion to $19.1 billion. The Fund may also invest in derivative instruments including futures or index futures that have a similar profile to the benchmark of the Fund. The Fund typically uses derivatives for the purpose of maintaining equity market exposure on its cash balance. The Fund may also invest in foreign securities. The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”). In managing the Fund, the Sub-Adviser uses a stock selection process that combines the discipline of quantitative screens with rigorous fundamental security analysis. The quantitative screens focus the fundamental analysis by identifying the stocks of companies with strong business momentum that demonstrate relative price strength, and have a perceived value not reflected in the current price. The objective of the fundamental analysis is to confirm the persistence of the company’s revenue and earnings growth and validate the Sub-Adviser’s expectations for earnings estimate revisions, particularly relative to consensus. A determination of reasonable valuation for individual securities is based on the judgment of the Sub-Adviser. The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others. The Fund may lend portfolio securities on a short-term or long-term basis, up to 331 / 3 % of its total assets.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds. Company   The price of a given company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless. Currency   To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Derivative Instruments   Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in interest rates and liquidity risk. The use of certain derivatives may also have a leveraging effect which may increase the volatility of the Fund and reduce its returns. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to the risk of improper valuation. Foreign Investments   Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Investment Model   The manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. Liquidity   If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund’s liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund. Market   Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. From time to time, the stock market may not favor the growth-oriented securities in which the Fund invests. Rather, the market could favor value-oriented securities or may not favor equities at all. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Fund costs and impair the ability of the Fund to achieve its investment objectives. Mid-Capitalization Company   Investments in mid-capitalization companies may involve greater risk than is customarily associated with larger, more established companies due to the greater business risks of smaller size, limited markets and financial resources, narrow product lines and the frequent lack of depth of management. Consequently, the securities of smaller companies may have limited market stability and may be subject to more abrupt or erratic market movements than securities of larger, more established growth companies or the market averages in general. Other Investment Companies   The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Fund may invest in other investment companies, you will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund. Securities Lending   Securities lending involves two primary risks: “investment risk” and “borrower default risk.” Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
Risk Lose Money [Text]	rr_RiskLoseMoney	You could lose money on an investment in the Fund.
Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	PERFORMANCE INFORMATION
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following information is intended to help you understand the risks of investing in the Fund. Because Class R6 shares of the Fund had not commenced operations as of the calendar year ended December 31, 2012, the following bar chart shows the changes in the Fund’s Class A shares’ performance from year to year, and the table compares the Fund’s Class A shares’ performance to the performance of a broad-based securities market index/indices for the same period. Class R6 shares and Class A shares of the Fund would have substantially similar performance because they invest in the same portfolio of securities. However, Class R6 shares’ performance would be higher than Class A shares’ performance because of the higher expenses paid by Class A shares. The Fund’s performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund’s Class A shares, but does not reflect the impact of contingent deferred sales charges. If it did, returns would be lower than those shown. The Fund’s past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to www.INGFunds.com/literature or call 1-800-992-0180.

Expense Example $

The Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example show costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Examples reflect applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods.

Portfolio Turnover % of average value of portfolio

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 transactions costs and may mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 89% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in common stocks of mid-sized U.S. companies. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy.

The Fund normally invests in companies that the sub-adviser (“Sub-Adviser”) believes have above average prospects for growth. For this Fund, mid-sized companies are those companies with market capitalizations that fall within the range of companies in the Russell Midcap^® Growth Index at the time of purchase. Capitalization of companies in the Russell Midcap^® Growth Index will change with market conditions. The market capitalization of companies in the Russell Midcap^® Growth Index as of June 29, 2012, ranged from $1.1 billion to $19.1 billion.

The Fund may also invest in derivative instruments including futures or index futures that have a similar profile to the benchmark of the Fund. The Fund typically uses derivatives for the purpose of maintaining equity market exposure on its cash balance. The Fund may also invest in foreign securities.

The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”).

In managing the Fund, the Sub-Adviser uses a stock selection process that combines the discipline of quantitative screens with rigorous fundamental security analysis. The quantitative screens focus the fundamental analysis by identifying the stocks of companies with strong business momentum that demonstrate relative price strength, and have a perceived value not reflected in the current price. The objective of the fundamental analysis is to confirm the persistence of the company’s revenue and earnings growth and validate the Sub-Adviser’s expectations for earnings estimate revisions, particularly relative to consensus. A determination of reasonable valuation for individual securities is based on the judgment of the Sub-Adviser.

The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 33¹ / ₃ % of its total assets.

PRINCIPAL RISKS

You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds.

Company   The price of a given company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.

Currency   To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.
Derivative Instruments   Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in interest rates and liquidity risk. The use of certain derivatives may also have a leveraging effect which may increase the volatility of the Fund and reduce its returns. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to the risk of improper valuation.
Foreign Investments   Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region.

Investment Model   The manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors.

Liquidity   If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund’s liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund.

Market   Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. From time to time, the stock market may not favor the growth-oriented securities in which the Fund invests. Rather, the market could favor value-oriented securities or may not favor equities at all. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Fund costs and impair the ability of the Fund to achieve its investment objectives.

Mid-Capitalization Company   Investments in mid-capitalization companies may involve greater risk than is customarily associated with larger, more established companies due to the greater business risks of smaller size, limited markets and financial resources, narrow product lines and the frequent lack of depth of management. Consequently, the securities of smaller companies may have limited market stability and may be subject to more abrupt or erratic market movements than securities of larger, more established growth companies or the market averages in general.

Other Investment Companies   The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Fund may invest in other investment companies, you will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund.

Securities Lending   Securities lending involves two primary risks: “investment risk” and “borrower default risk.” Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

PERFORMANCE INFORMATION

The following information is intended to help you understand the risks of investing in the Fund. Because Class R6 shares of the Fund had not commenced operations as of the calendar year ended December 31, 2012, the following bar chart shows the changes in the Fund’s Class A shares’ performance from year to year, and the table compares the Fund’s Class A shares’ performance to the performance of a broad-based securities market index/indices for the same period. Class R6 shares and Class A shares of the Fund would have substantially similar performance because they invest in the same portfolio of securities. However, Class R6 shares’ performance would be higher than Class A shares’ performance because of the higher expenses paid by Class A shares. The Fund’s performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund’s Class A shares, but does not reflect the impact of contingent deferred sales charges. If it did, returns would be lower than those shown. The Fund’s past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to www.INGFunds.com/literature or call 1-800-992-0180.

Expense Example $

The Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example show costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Yr	3 Yrs	5 Yrs	10 Yrs

The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods.

Portfolio Turnover % of average value of portfolio

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 transactions costs and may mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 72% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in common stocks of smaller, lesser-known U.S. companies. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy.

The Fund normally invests in companies that the sub-adviser (“Sub-Adviser”) believes have above average prospects for growth. For this Fund, smaller companies are those with market capitalizations that fall within the range of companies in the Russell 2000^® Growth Index at the time of purchase. The Russell 2000^® Growth Index is an index that measures the performance of small growth companies. Capitalization of companies in the Russell 2000^® Growth Index will change with market conditions. The market capitalization of companies in the Russell 2000^® Growth Index as of June 29, 2012, ranged from $53.3 million to $3.8 billion.

The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”).

The Sub-Adviser uses a disciplined combination of quantitative screens and bottom-up fundamental security analysis to build a broadly diversified portfolio of companies that the Sub-Adviser believes will have improving bottom lines with reasonable valuation, and whose stocks demonstrate relative strength. The focus of company analysis is upon the prospects for continuing bottom-line growth, balance sheet strength, and cash flow characteristics. A determination of reasonable valuation for individual securities is based on the judgment of the Sub-Adviser.

The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 33¹ / ₃ % of its total assets.

PRINCIPAL RISKS

You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds.

Company   The price of a given company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.

Investment Model   The manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors.

Liquidity   If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund’s liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund.

Market   Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. From time to time, the stock market may not favor the growth-oriented securities in which the Fund invests. Rather, the market could favor value-oriented securities or may not favor equities at all. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Fund costs and impair the ability of the Fund to achieve its investment objectives.

Small-Capitalization Company   Investments in small-capitalization companies may involve greater risk than is customarily associated with larger, more established companies due to the greater business risks of small size, limited markets and financial resources, narrow product lines and the frequent lack of depth of management. The securities of smaller companies are often traded over-the-counter and may not be traded in volume typical on a national securities exchange.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of dividend-paying, large-capitalization issuers. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy. Equity securities include common and preferred stocks, warrants, and convertible securities. The sub-adviser (“Sub-Adviser”) defines large-capitalization companies as companies with market capitalizations that fall within the collective range of companies within the Russell 1000® Value Index (“Index”) at the time of purchase. The market capitalization range will change with market conditions as the market capitalization range of the companies in the Index changes. The market capitalization of companies in the Index as of June 29, 2012 ranged from $670.9 million to $400.1 billion. The Fund may invest in foreign securities, including companies located in countries with emerging securities markets, when the Sub-Adviser believes they present attractive investment opportunities. The Sub-Adviser seeks to construct a portfolio of securities with a dividend yield that exceeds the average dividend yield of the companies included in the Russell 1000® Value Index. The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”). The Sub-Adviser uses a valuation-based screening process to assist in the selection of companies according to criteria which include the following: an above-average dividend yield, and stability and growth of the dividend; market capitalization that is usually above $1 billion (although the Fund may also invest up to 20% of its assets in small- and mid-capitalization companies); and the potential for growth of the dividend yield over several years. The Sub-Adviser may from time to time select securities that do not meet all of these criteria. The Sub-Adviser then conducts intensive fundamental research on each company to evaluate its growth, profitability, and valuation characteristics. The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others. The Fund may lend portfolio securities on a short-term or long-term basis, up to 331 / 3 % of its total assets.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds. Company   The price of a given company's stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless. Convertible Securities   Convertible securities are securities that are convertible into or exercisable for common stocks at a stated price or rate. Convertible securities are subject to the usual risks associated with debt securities, such as interest rate and credit risk. In addition, because convertible securities react to changes in the value of the stocks into which they convert, they are subject to market risk. Credit   Prices of bonds and other debt instruments can fall if the issuer's actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay altogether. Currency   To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Dividend   Companies that issue dividend yielding equity securities are not required to continue to pay dividends on such securities. Therefore, there is the possibility that such companies could reduce or eliminate the payment of dividends in the future. Foreign Investments/Developing and Emerging Markets Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets. Interest Rate   With bonds and other fixed rate debt instruments, a rise in interest rates generally causes values to fall; conversely, values generally rise as interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. In the case of inverse securities, the interest rate generally will decrease when the market rate of interest to which the inverse security is indexed decreases. As of the date of this Prospectus, interest rates in the United States are at or near historic lows, which may increase the Fund's exposure to risks associated with rising interest rates. Investment Model   The manager's proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. Liquidity   If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund's manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund's liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund. Market   Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Fund costs and impair the ability of the Fund to achieve its investment objectives. Market Capitalization   Stocks fall into three broad market capitalization categories - large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-sized companies causing the Fund that invests in these companies to increase in value more rapidly than a fund that invests in larger, fully-valued companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, and a more limited trading market for their stocks as compared with larger companies. As a result, stocks of mid- and small-capitalization companies may decline significantly in market downturns. Other Investment Companies   The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Fund may invest in other investment companies, you will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund. Securities Lending   Securities lending involves two primary risks: "investment risk" and "borrower default risk." Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner. Value Investing   Securities that appear to be undervalued may never appreciate to the extent expected. Further, because the prices of value-oriented securities tend to correlate more closely with economic cycles than growth-oriented securities, they generally are more sensitive to changing economic conditions, such as changes in interest rates, corporate earnings and industrial production. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	PERFORMANCE INFORMATION
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following information is intended to help you understand the risks of investing in the Fund. Because Class R6 shares of the Fund had not commenced operations as of the calendar year ended December 31, 2012, the following bar chart shows the changes in the Fund’s Class A shares’ performance from year to year, and the table compares the Fund’s Class A shares’ performance to the performance of a broad-based securities market index/indices for the same period. Class R6 shares and Class A shares of the Fund would have substantially similar performance because they invest in the same portfolio of securities. However, Class R6 shares’ performance would be higher than Class A shares’ performance because of the higher expenses paid by Class A shares. The Fund’s performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund’s Class A shares, but does not reflect the impact of contingent deferred sales charges. If it did, returns would be lower than those shown. The Fund’s past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to www.INGFunds.com/literature or call 1-800-992-0180.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example show costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods.

Portfolio Turnover % of average value of portfolio

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 transactions costs and may mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 84% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of dividend-paying, large-capitalization issuers. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy. Equity securities include common and preferred stocks, warrants, and convertible securities. The sub-adviser (“Sub-Adviser”) defines large-capitalization companies as companies with market capitalizations that fall within the collective range of companies within the Russell 1000® Value Index (“Index”) at the time of purchase. The market capitalization range will change with market conditions as the market capitalization range of the companies in the Index changes. The market capitalization of companies in the Index as of June 29, 2012 ranged from $670.9 million to $400.1 billion. The Fund may invest in foreign securities, including companies located in countries with emerging securities markets, when the Sub-Adviser believes they present attractive investment opportunities.

The Sub-Adviser seeks to construct a portfolio of securities with a dividend yield that exceeds the average dividend yield of the companies included in the Russell 1000® Value Index. The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”).

The Sub-Adviser uses a valuation-based screening process to assist in the selection of companies according to criteria which include the following:

• an above-average dividend yield, and stability and growth of the dividend;

• market capitalization that is usually above $1 billion (although the Fund may also invest up to 20% of its assets in small- and mid-capitalization companies); and

• the potential for growth of the dividend yield over several years.

The Sub-Adviser may from time to time select securities that do not meet all of these criteria. The Sub-Adviser then conducts intensive fundamental research on each company to evaluate its growth, profitability, and valuation characteristics.

The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 331 / 3 % of its total assets.

PRINCIPAL RISKS

You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds.

Company   The price of a given company's stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.

Convertible Securities   Convertible securities are securities that are convertible into or exercisable for common stocks at a stated price or rate. Convertible securities are subject to the usual risks associated with debt securities, such as interest rate and credit risk. In addition, because convertible securities react to changes in the value of the stocks into which they convert, they are subject to market risk.

Credit   Prices of bonds and other debt instruments can fall if the issuer's actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay altogether.
Currency   To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Dividend   Companies that issue dividend yielding equity securities are not required to continue to pay dividends on such securities. Therefore, there is the possibility that such companies could reduce or eliminate the payment of dividends in the future.

Foreign Investments/Developing and Emerging Markets Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets.
Interest Rate   With bonds and other fixed rate debt instruments, a rise in interest rates generally causes values to fall; conversely, values generally rise as interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. In the case of inverse securities, the interest rate generally will decrease when the market rate of interest to which the inverse security is indexed decreases. As of the date of this Prospectus, interest rates in the United States are at or near historic lows, which may increase the Fund's exposure to risks associated with rising interest rates.

Investment Model   The manager's proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors.

Liquidity   If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund's manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund's liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund.

Market   Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Fund costs and impair the ability of the Fund to achieve its investment objectives.

Market Capitalization   Stocks fall into three broad market capitalization categories - large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-sized companies causing the Fund that invests in these companies to increase in value more rapidly than a fund that invests in larger, fully-valued companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, and a more limited trading market for their stocks as compared with larger companies. As a result, stocks of mid- and small-capitalization companies may decline significantly in market downturns.

Other Investment Companies   The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Fund may invest in other investment companies, you will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund.

Securities Lending   Securities lending involves two primary risks: "investment risk" and "borrower default risk." Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

Value Investing   Securities that appear to be undervalued may never appreciate to the extent expected. Further, because the prices of value-oriented securities tend to correlate more closely with economic cycles than growth-oriented securities, they generally are more sensitive to changing economic conditions, such as changes in interest rates, corporate earnings and industrial production.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

PERFORMANCE INFORMATION

The following information is intended to help you understand the risks of investing in the Fund. Because Class R6 shares of the Fund had not commenced operations as of the calendar year ended December 31, 2012, the following bar chart shows the changes in the Fund’s Class A shares’ performance from year to year, and the table compares the Fund’s Class A shares’ performance to the performance of a broad-based securities market index/indices for the same period. Class R6 shares and Class A shares of the Fund would have substantially similar performance because they invest in the same portfolio of securities. However, Class R6 shares’ performance would be higher than Class A shares’ performance because of the higher expenses paid by Class A shares. The Fund’s performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund’s Class A shares, but does not reflect the impact of contingent deferred sales charges. If it did, returns would be lower than those shown. The Fund’s past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to www.INGFunds.com/literature or call 1-800-992-0180.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.
