Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund and underlying funds (including exchange-traded funds (ETFs)) may pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their portfolios). The Fund will indirectly bear the expenses associated with portfolio turnover of the underlying funds. 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 example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||
Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is a “fund-of-funds” and seeks to achieve its objective by investing in a combination of underlying funds, including mutual funds and exchange-traded funds (ETFs) (collectively, Underlying Funds), representing different asset classes, potentially including an allocation to alternative investment strategies. Under normal market conditions, the Fund intends to invest in each asset class within the following target asset allocation ranges:
* Market appreciation or depreciation may cause the Fund to be temporarily outside the ranges identified in the table. The Investment Manager may modify the target allocation ranges only upon approval of the Fund’s Board of Trustees. Columbia Management Investment Advisers, LLC (the Investment Manager), allocates the Fund’s assets within and across different asset classes through investments in Underlying Funds, potentially including an allocation to alternative investment strategy funds, in an effort to achieve the Fund’s investment objective of providing a high level of current income and growth of capital. Typically, asset allocation changes will be made monthly to refine the Fund’s positioning, but may be made more or less frequently depending upon then-current allocations. In pursuit of the Fund’s investment objective, the Investment Manager chooses investments by: ◾ Evaluating the Fund’s total exposure to sectors, industries, issuers and securities relative to the Fund’s indices; ◾ Analyzing factors such as credit quality, interest rate outlook and price; and ◾ Targeting certain Underlying Funds that invest in lower-quality (junk) bonds and foreign investments as attractive opportunities arise. The Investment Manager relies on various qualitative and quantitative inputs to tactically allocate the Fund’s assets across the different asset classes and investment categories. Investment Category Allocation. Within the equity and fixed income asset classes, the Investment Manager establishes allocations for the Fund, seeking to achieve the Fund’s investment objective by investing in defined investment categories. Fixed income investment categories include Underlying Funds that invest in: government bonds, U.S. investment grade bonds, U.S. high yield bonds, floating rate securities, emerging market bonds, multi-sector bonds and short and ultra-short bonds. These fixed income Underlying Funds include those that invest in mortgage- and asset-backed securities. The Investment Manager also may allocate assets to money market (cash) or alternative investment strategies. Equity investment categories include Underlying Funds that invest in: U.S. large cap, mid cap and small cap equities (including growth, value and core/blend styles), international equities (including emerging market securities) and specialty funds, including those that invest in convertible securities, real estate equities, and technology-focused investments. The target allocation range constraints set forth in Table 1 are intended to promote diversification within asset classes, and the Investment Manager takes into account factors such as style, sector, market capitalization, geographic location, credit quality, interest rate outlook, and yield potential. Proposed allocation shifts are reviewed and approved by the Investment Manager as part of its qualitative review.

Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund’s Class A share performance (without sales charges) has varied for each full calendar year shown. If the sales charges were reflected, returns shown would be lower. The table below the bar chart compares the Fund’s returns (after applicable sales charges shown in the Shareholder Fees table in this prospectus) for the periods shown with a blended benchmark that is intended to provide a measure of the Fund's performance given its investment strategies, as well as three other measures of performance for markets in which the Fund may invest. The performance of one or more share classes shown in the table below begins before the indicated inception date for such share class. The returns shown for each such share class include the returns of the Fund’s Class A shares (without applicable sales charges) for periods prior to its inception date. Except for differences in annual returns resulting from differences in expenses and sales charges (where applicable), the share classes of the Fund would have substantially similar annual returns because all share classes of the Fund invest in the same portfolio of securities. The after-tax returns shown in the Average Annual Total Returns table below are calculated using the highest historical individual U.S. federal marginal income tax rates in effect during the period indicated in the table and do not reflect the impact of state, local or foreign taxes. Your actual after-tax returns will depend on your personal tax situation and may differ from those shown in the table. In addition, the after-tax returns shown in the table do not apply to shares held in tax-advantaged accounts such as 401(k) plans or Individual Retirement Accounts (IRAs). The after-tax returns are shown only for Class A shares and will vary for other share classes.

Risk [Text Block] | rr_RiskTextBlock | Allocation Risk. Because the Fund uses an asset allocation strategy in pursuit of its investment objective, there is a risk that the Fund's allocation among asset classes, investments, managers, strategies and/or investment styles will cause the Fund's shares to lose value or cause the Fund to underperform other funds with similar investment objectives and/or strategies, or that the investments themselves will not produce the returns expected.

Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Alternative Strategies Investment Risk. An investment in alternative investment strategies (Alternative Strategies), whether through direct investment or through one or more Underlying Funds that use Alternative Strategies, involves risks, which may be significant. Alternative Strategies may include strategies, instruments or other assets, such as derivatives, that seek investment returns uncorrelated with the broad equity and fixed income/debt markets, as well as those providing exposure to other markets (such as commodity markets), including but not limited to absolute (positive) return strategies. Alternative Strategies may fail to achieve their desired performance, market or other exposure, or their returns (or lack thereof) may be more correlated with the broad equity and/or fixed income/debt markets than was anticipated, and the Fund may lose money. Some Alternative Strategies may be considered speculative.

Columbia Income Builder Fund | Counterparty Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. Counterparty risk is the risk that a counterparty to a transaction in a financial instrument held by the Fund or by a special purpose or structured vehicle invested in by the Fund may become insolvent or otherwise fail to perform its obligations. As a result, the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Columbia Income Builder Fund | Credit Risks [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Credit Risk. Credit risk is the risk that the value of debt instruments may decline if the issuer thereof defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies, such as S&P Global Ratings, Moody’s Investors Service, Inc. (Moody’s), Fitch Ratings, Inc. (Fitch), Morningstar DBRS (DBRS) and Kroll Bond Rating Agency, LLC (KBRA), assign credit ratings to certain debt instruments to indicate their credit risk. A rating downgrade by such agencies can negatively impact the value of such instruments. Lower-rated or unrated instruments held by the Fund may present increased credit risk as compared to higher-rated instruments. Non-investment grade debt instruments may be subject to greater price fluctuations and are more likely to experience a default than investment grade debt instruments and therefore may expose the Fund to increased credit risk.

Columbia Income Builder Fund | Derivatives Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives may involve significant risks. Derivatives are financial instruments with a value in relation to, or derived from, the value of an underlying asset(s) or other reference, such as an index, rate or other economic indicator (each an underlying reference). Derivatives may include those that are privately placed or otherwise exempt from SEC registration, including certain Rule 144A eligible securities. Derivatives could result in Fund losses if the underlying reference does not perform as anticipated. Use of derivatives is a highly specialized activity that can involve investment techniques, risks, and tax planning different from those associated with more traditional investment instruments. The Fund’s derivatives strategy may not be successful and use of certain derivatives could result in substantial, potentially unlimited, losses to the Fund regardless of the Fund’s actual investment. A relatively small movement in the price, rate or other economic indicator associated with the underlying reference may result in substantial losses for the Fund. Derivatives may be more volatile than other types of investments. The value of derivatives may be influenced by a variety of factors, including national and international political and economic developments. Potential changes to the regulation of the derivatives markets may make derivatives more costly, may limit the market for derivatives, or may otherwise adversely affect the value or performance of derivatives. Derivatives can increase the Fund’s risk exposure to underlying references and their attendant risks, such as credit risk, market risk, foreign currency risk and interest rate risk, while exposing the Fund to correlation risk, counterparty risk, hedging risk, inflation risk, leverage risk, liquidity risk, pricing risk and volatility risk.

Columbia Income Builder Fund | Exchange Traded Fund ETF Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Exchange-Traded Fund (ETF) Risk. Investments in ETFs have unique characteristics, including, but not limited to, the expense structure and additional expenses associated with investing in ETFs. ETFs are subject to, among other risks, tracking risk and passive and, in some cases, active investment risk. In addition, shareholders bear both their proportionate share of the Fund’s expenses, and indirectly the ETF’s expenses, incurred through the Fund’s ownership of the ETF. Because the expenses and costs of an underlying ETF are shared by its investors, redemptions by other investors in the ETF could result in decreased economies of scale and increased operating expenses for such ETF. The ETFs may not achieve their investment objective. The Fund, through its investment in ETFs, may not achieve its investment objective.

Columbia Income Builder Fund | Foreign Securities Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Foreign Securities Risk. Investments in or exposure to securities of foreign companies may involve heightened risks relative to investments in or exposure to securities of U.S. companies. Investing in securities of foreign companies subjects the Fund to the risks associated with an issuer’s (and any of its related companies’) country of organization and places of business operations, including risks related to political, regulatory, economic, social, diplomatic and other conditions or events (including, for example, military confrontations and actions, war, other conflicts, terrorism and disease/virus outbreaks and epidemics) occurring in the country or region, as well as risks associated with less developed custody and settlement practices. Foreign securities may be more volatile and less liquid than securities of U.S. companies, and are subject to the risks associated with potential imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country. In addition, foreign governments may impose withholding or other taxes on the Fund’s income, capital gains or proceeds from the disposition of foreign securities, which could reduce the Fund’s return on such securities.

Columbia Income Builder Fund | Fund of Funds Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Fund-of-Funds Risk. Determinations regarding asset classes or selection of Underlying Funds and the Fund’s allocations thereto may not successfully achieve the Fund’s investment objective, in whole or in part. The ability of the Fund to realize its investment objective will depend, in large part, on the extent to which the Underlying Funds realize their investment objective. There is no guarantee that the Underlying Funds will achieve their respective investment objectives. The Fund is exposed to the same risks as the Underlying Funds in direct proportion to the allocation of its assets among the Underlying Funds. Therefore, to the extent that the Fund invests significantly in a particular Underlying Fund, the Fund’s performance would be significantly impacted by the performance of such Underlying Fund. Generally, by investing in a combination of Underlying Funds, the Fund has exposure to the risks of many areas of the market. By concentrating its investments in relatively few Underlying Funds, the Fund may have more concentrated market exposures, subjecting the Fund to greater risk of loss should those markets decline or fail to rise. The performance of Underlying Funds could be adversely affected if other entities that invest in the same funds make relatively large investments or redemptions in such funds. The Fund, and its shareholders, indirectly bear a portion of the expenses of any funds in which the Fund invests. Because the expenses and costs of each Underlying Fund are shared by its investors, redemptions by other investors in an Underlying Fund could result in decreased economies of scale and increased operating expenses for such Underlying Fund. The Investment Manager has a conflict of interest in choosing affiliated funds over unaffiliated funds when selecting and investing in Underlying Funds because it receives management fees from affiliated funds, and it has a conflict in choosing among affiliated funds when selecting and investing in Underlying Funds, because the fees paid to it by certain affiliated funds are higher than the fees paid by other affiliated funds. Also, to the extent that the Fund is constrained/restricted from investing (or investing further) in a particular Underlying Fund for one or more reasons (e.g., Underlying Fund capacity constraints or regulatory restrictions) or if the Fund chooses to sell its investment in an Underlying Fund because of poor investment performance or for other reasons, the Fund may have to invest in another fund(s), including less desirable funds – from a strategy or investment performance standpoint – which could have a negative impact on Fund performance. In addition, Fund performance could be negatively impacted if the Investment Manager is unable to identify an appropriate alternate fund(s) in a timely manner or at all.

Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Growth Securities Risk. Growth securities typically trade at a higher multiple of earnings than other types of equity securities. Accordingly, the market values of growth securities may never reach their expected market value and may decline in price. In addition, growth securities, at times, may not perform as well as value securities or the stock market in general, and may be out of favor with investors for varying periods of time. Growth securities may also be sensitive to movements in interest rates.

Columbia Income Builder Fund | High Yield Investments Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | High-Yield Investments Risk. Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called “high-yield” or “junk” bonds) and unrated debt instruments of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade debt instruments. In addition, these investments have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal.

|||||||||||
Columbia Income Builder Fund | Interest Rate Risks [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher periods of inflation could lead such authorities to raise interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund's performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Columbia Income Builder Fund | Issuer Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Issuer Risk. An issuer in which the Fund invests or to which it has exposure may perform poorly or below expectations, and the value of its securities may therefore decline, which may negatively affect the Fund’s performance. Underperformance of an issuer may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters, military confrontations and actions, war, other conflicts, terrorism, disease/virus outbreaks, epidemics or other events, conditions and factors which may impair the value of your investment in the Fund. ◾ Small- and Mid-Cap Stock Risk. Investments in small- and mid-capitalization companies (small- and mid-cap companies) often involve greater risks than investments in larger, more established companies (larger companies) because small- and mid-cap companies tend to have less predictable earnings and may lack the management experience, financial resources, product diversification and competitive strengths of larger companies. Securities of small- and mid-cap companies may be less liquid and more volatile than the securities of larger companies. ◾ Large-Cap Stock Risk. Investments in larger companies may involve certain risks associated with their larger size. For instance, larger companies may be less able to respond quickly to new competitive challenges, such as changes in consumer tastes or innovation from smaller competitors. Also, larger companies are sometimes less able to achieve as high growth rates as successful smaller companies, especially during extended periods of economic expansion. |

Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Market Risk. The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, other conflicts, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.

Columbia Income Builder Fund | Money Market Fund Investment Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Money Market Fund Investment Risk. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Certain money market funds float their NAV while others seek to preserve the value of investments at a stable NAV (typically, $1.00 per share). An investment in a money market fund, even an investment in a fund seeking to maintain a stable NAV per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. Certain money market funds may impose a discretionary liquidity fee of up to 2% on redemptions if that fee is determined to be in the best interest of the fund and, by October 2, 2024 or earlier, certain money market funds must impose a mandatory liquidity fee on redemptions if net redemptions exceed 5% of their net assets. Such fees, if imposed, will reduce the amount the Fund receives on redemptions. In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market funds in which it invests, including affiliated money market funds. By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. To the extent the Fund invests in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from the Fund’s investments in such instruments. Money market funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds.

Columbia Income Builder Fund | Prepayment and Extension Risk [Member] | |||||||||||||
Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Prepayment and Extension Risk. Prepayment and extension risk is the risk that a bond or other security or investment might, in the case of prepayment risk, be called or otherwise converted, prepaid or redeemed before maturity and, in the case of extension risk, that the investment might not be called as expected. In the case of prepayment risk, if the investment is converted, prepaid or redeemed before maturity, the portfolio managers may not be able to invest the proceeds in other investments providing as high a level of income, resulting in a reduced yield to the Fund. As interest rates decrease or spreads narrow on such securities, the likelihood of prepayment increases. Conversely, extension risk is the risk that an unexpected rise in interest rates will extend the life of a security beyond the prepayment time. If the Fund’s investments are locked in at a lower interest rate for a longer period of time, the portfolio managers may be unable to capitalize on securities with higher interest rates or wider spreads.

Risk [Text Block] | rr_RiskTextBlock | Value Securities Risk. Value securities are securities of companies that may have experienced, for example, adverse business, industry or other developments or may be subject to special risks that have caused the securities to be out of favor and, in turn, potentially undervalued. The market value of a portfolio security may not meet the perceived value assessment of that security as determined by the portfolio managers, or may decline in price, even though the securities are already believed to be undervalued by the portfolio managers. There is also a risk that it may take longer than expected for the value of these investments to rise to the perceived value as determined by the portfolio managers. In addition, value securities, at times, may not perform as well as growth securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Risk/Return: | rr_RiskReturnAbstract | ||||||||||||
Risk [Text Block] | rr_RiskTextBlock | Emerging Market Securities Risk. Securities issued by foreign governments or companies in emerging market countries, such as China, Russia and certain countries in Eastern Europe, the Middle East, Asia, Latin America or Africa, are more likely to have greater exposure to the risks of investing in foreign securities that are described in Foreign Securities Risk. In addition, emerging market countries are more likely to experience instability resulting, for example, from rapid changes or developments in social, political, economic or other conditions. Their economies are usually less mature and their securities markets are typically less developed with more limited trading activity (i.e., lower trading volumes and less liquidity) than more developed countries. Emerging market securities tend to be more volatile, and may be more susceptible to market manipulation, than securities in more developed markets. Many emerging market countries are heavily dependent on international trade and have fewer trading partners, which makes them more sensitive to world commodity prices and economic downturns in other countries, and some have a higher risk of currency devaluations. Due to the differences in the nature and quality of financial information of issuers of emerging market securities, including auditing and financial reporting standards, financial information and disclosures about such issuers may be unavailable or, if made available, may be considerably less reliable than publicly available information about other foreign securities.
