Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock
The following tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen mutual funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “How You Can Buy and Sell Shares” on page 34 of the Fund’s prospectus and “Purchase and Redemption of Fund Shares” on page S-62 of the Fund’s statement of additional information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in the appendix to the Fund’s prospectus entitled “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries.”
The tables and examples below do not reflect any commissions that shareholders may be required to pay directly to their financial intermediaries when buying or selling Class I shares.

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 example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 18% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Fund's operating expenses remain the same and that the fee waivers currently in place are not renewed beyond July 31, 2026. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
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 in dividend-paying equity securities, which include preferred securities. Under normal market conditions, the Fund invests at least 80% of its net assets in non-U.S. securities. The Fund may invest up to 10% of its net assets in companies located in emerging market countries. The Fund may invest in small-, mid- and large-cap companies.
The Fund’s sub-adviser is focused on bottom-up fundamental analysis to identify what it believes to be the highest quality companies that meet the Fund’s investment criteria. When selecting companies, the sub-adviser evaluates certain factors, including a sound business model, strong overall financial position, earnings growth, return on equity, quality of management, potential for dividend growth, market valuation, the commitment to return cash to shareholders, and individual country factors, including macroeconomic and political risk factors.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. All 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. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.
Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers had not been in place, returns would have been reduced.

Nuveen International Dividend Growth Fund | Risk Not Insured Depository Institution [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Nuveen International Dividend Growth Fund | Active Management Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Active Management Risk—The Fund’s sub-adviser actively manages the Fund’s investments. Consequently, the Fund is subject to the risk that the investment techniques and risk analyses employed by the Fund’s sub-adviser may not produce the desired results. This could cause the Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
Nuveen International Dividend Growth Fund | Currency Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities, and gains and losses realized on the sale of such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.
Nuveen International Dividend Growth Fund | Cybersecurity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Fund assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Fund to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund, its service providers or the issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.
Nuveen International Dividend Growth Fund | Dividend Paying Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Dividend-Paying Security Risk—The Fund’s investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. Securities of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time. Depending on market conditions, dividend paying securities that meet the Fund’s investment objectives may not be widely available or may be
concentrated in only a few market sectors. This may limit the ability of the Fund to produce income while remaining diversified.
Nuveen International Dividend Growth Fund | Emerging Markets Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund’s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund’s sub-adviser to evaluate local companies or their potential impact on the Fund’s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.
Nuveen International Dividend Growth Fund | Equity Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Equity Security Risk—Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market. Holders of common stock generally are subject to more risks than holders of preferred securities because the status of common stockholders upon the bankruptcy of the issuer is subordinated to that of preferred security holders. Given the Fund's focus on dividend-paying securities, the Fund may, from time to time, have a greater exposure to higher dividend-yield sectors and industries than the broad equity market which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.
Nuveen International Dividend Growth Fund | Foreign Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Foreign Investment Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. The Fund currently invests a significant portion of its assets in companies located in the United Kingdom, although this may change over time.
Nuveen International Dividend Growth Fund | Market Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Market Risk—The market value of the Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Fund’s investments whether or not the Fund invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Fund’s assets can decline.
Nuveen International Dividend Growth Fund | Preferred Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Preferred Security Risk—Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having fixed interest rates or dividends, which may result in a decline in value in a rising interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.
Nuveen International Dividend Growth Fund | Small and Mid Cap Company Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Small- and Mid-Cap Company Risk—Securities of small-cap companies involve substantial risk. Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations and lower liquidity, than security prices of larger, more established companies or broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price. While mid-cap securities may be slightly less volatile than small-cap securities, they still involve similar risks.
