The tables below describe the fees and expenses that you may pay if you buy and hold shares of the Fund. In addition to the fees and expenses described below, you may also be required to pay brokerage commissions on purchases and sales of the Class P 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 Class A shares of eligible funds that are part of the family of mutual funds sponsored by Allianz. More information about these and other discounts is available in the “Classes of Shares” section beginning on page 97 of the Fund’s prospectus or from your financial advisor. In addition, if you purchase shares through a specific intermediary, you may be subject to different sales charges including reductions in or waivers of such charges. More information about these intermediary-specific sales charge variations is available in Appendix A to the Fund’s prospectus (“Intermediary Sales Charge Discounts and Waivers”).

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). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2020 was 126% of the average value of its portfolio. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text] rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees Total Annual Fund Operating Expenses do not match the Ratio of Expenses to Average Net Assets of the Fund as set forth in the Financial Highlights table of the Fund’s prospectus, in part, because the Ratio of Expenses to Average Net Asset in the prospectus reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.
Expense Example [Heading] rr_ExpenseExampleHeading Examples.
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions whether you redeem your shares at the end of each period or do not redeem your shares. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in common stocks and other equity securities of companies with smaller market capitalizations. The Fund currently considers smaller market capitalization companies to be companies with market capitalizations of between $100 million and the greater of $4 billion or the capitalization of the largest company in the Russell 2000 Index. As of June 30, 2020, the market capitalization of the largest company in the Russell 2000 Index was $5.8 billion. The Fund may continue to hold securities of a portfolio company that subsequently appreciates above the smaller market capitalization threshold, including in situations where such securities continue to trade at valuations the portfolio managers consider attractive. Because of this, the Fund may have less than 80% of its net assets in smaller market capitalization stocks at any given time. The Fund normally invests significantly in securities of companies that the portfolio managers expect will generate income (for example, by paying dividends). The portfolio managers use a value investing style focusing on companies whose securities the portfolio managers believe have attractive valuation and fundamental strength. The portfolio managers partition the Fund’s selection universe by industry and then identify what they believe to be the most attractively valued securities in each industry to determine potential holdings for the Fund representing a broad range of industry groups. The portfolio managers use initial parameters and quantitative tools to narrow the Fund’s selection universe and also review and consider fundamental changes. After narrowing the universe through a combination of qualitative analysis and fundamental research, the portfolio managers select securities for the Fund. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the Fund may invest a substantial portion of its assets in real estate investment trusts (REITs). The Fund may also invest a portion of its assets in non-U.S. securities (including through American Depositary Receipts (ADRs)), including emerging market securities. The Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. Although the Fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund, which could adversely affect its net asset value, yield and total return, are (in alphabetical order after the first four risks):

Market Risk:  The Fund will be affected by factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them.


Issuer Risk:  The Fund will be affected by factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers.


Equity Securities Risk:  Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer.


Smaller Company Risk:  Securities issued by smaller companies may be more volatile and present increased liquidity risk relative to securities issued by larger companies.


Credit and Counterparty Risk:  An issuer or counterparty may default on obligations.


Currency Risk:  The values of non-U.S. securities may fluctuate with currency exchange rates and exposure to non-U.S. currencies may subject the Fund to the risk that those currencies will decline in value relative to the U.S. dollar.


Derivatives Risk:  Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation.


Emerging Markets Risk:  Non-U.S. investment risk may be particularly high to the extent that the Fund invests in emerging market securities. These securities may present market, credit, currency, liquidity, legal, political, technical and other risks different from, or greater than, the risks of investing in developed countries.


Focused Investment Risk:  To the extent the Fund focuses its investments on a limited number of issuers, sectors, industries or geographic regions, it may be subject to increased risk and volatility.


Liquidity Risk:  To the extent the Fund invests in less liquid securities or the level of liquidity in a particular market is constrained, the lack of an active market for investments may cause delay in disposition or force a sale below fair value.


Management Risk:  The Fund will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management.


Non-U.S. Investment Risk:  Non-U.S. securities markets and issuers may be more volatile, smaller, less liquid, less transparent and subject to less oversight, particularly in emerging markets.


REIT and Real Estate-Related Investment Risk:  Adverse changes in the real estate markets may affect the value of REIT investments or real estate-linked derivatives.


Turnover Risk:  High levels of portfolio turnover increase transaction costs and taxes and may lower investment performance.


Please see “Summary of Principal Risks” in the Fund’s prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. 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.

Bar Chart and Performance Table [Heading] rr_BarChartAndPerformanceTableHeading Performance Information
Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock
The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Class A shares, but do not reflect the impact of sales charges (loads). If they did, returns would be lower than those shown. Other share classes would have different performance due to the different expenses they bear. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are different from the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit us.allianzgi.com for more current performance information.
