Here are the frequently asked questions about Ant Design and antd that you should look up before you ask in the community or create a new issue. We also maintain a FAQ issues label for common github issues.

Will you provide Sass/Stylus(etc.) style files in addition to the Less style files currently included?

There is currently no plan to add support for Sass/Stylus(etc.) style files, but using tools on Google you can easily convert the provided Less files to your desired style format.

Select Dropdown DatePicker TimePicker Popover Popconfirm disappears when I click another popup component inside it. How do I resolve this?

This is an old bug that has been fixed since v3.11.x. If you're using an older version, you can use <Select getPopupContainer={trigger => trigger.parentElement}> to render a component inside Popover. (Or other getXxxxContainer props)

Related issue: #3487 #3438

How do I prevent Select Dropdown DatePicker TimePicker Popover Popconfirm scrolling with the page?

Use <Select getPopupContainer={trigger => trigger.parentElement}> (API reference) to render a component inside the scroll area. If you need to config this globally in your application, try <ConfigProvider getPopupContainer={trigger => trigger.parentElement}> (API reference)

And make sure that parentElement is position: relative or position: absolute.

How do I modify the default theme of Ant Design?

See: https://ant.design/docs/react/customize-theme .

How do I modify Menu/Button(etc.)'s style?

While you can override a component's style, we don't recommend doing so. antd is not only a set of React components, but also a design specification as well.

How do I replace Moment.js with Day.js to reduce bundle size？

Please refer to Replace Moment.js.

It doesn't work when I change defaultValue dynamically.

The defaultXxxx (e.g. defaultValue) of Input/Select(etc...) only works on the first render. It is a specification of React. Please read React's documentation.

Why does modifying props in mutable way not trigger a component update?

antd use shallow compare of props to optimize performance. You should always pass the new object when updating the state. Please ref React's document

After I set the value of an Input/Select(etc.) component, the value cannot be changed by user's action.

Try defaultValue or onChange to change value, and please read React's documentation.

Components are not vertically aligned when placed in single row.

Try Space component to make them aligned.

antd overrides my global styles

Yes, antd is designed to help you develop a complete background application. To do so, we override some global styles for styling convenience, and currently these cannot be removed or changed. More info at https://github.com/ant-design/ant-design/issues/4331 .

Alternatively, follow the instructions in How to avoid modifying global styles?

I cannot install antd and antd's dependencies in mainland China.

To potentially solve this, try cnpm.

I set dependencies.antd as the git repository in package.json, but it doesn't work.

Please install antd with either npm or yarn.

message and notification is lower case, but other components are capitalized. Is this a typo?

No, message is just a function, not a React Component, thus it is not a typo that it is in lower case.

antd doesn't work well in mobile.

Please check And Design Mobile as a possible solution, as antd has not been optimized to work well on mobile. You can also try the react-component repositories which start with 'm-' 'rn-', which are also designed for mobile.

Does antd supply standalone files like 'React'?

Yes, you can import antd with script tag, but we recommend using npm to import antd, as it is simple and easy to maintain.

I can't visit icon in my network environment.

You should deploy the iconfont files to your network by following this example. #1070

After 3.9.x we will also switch to using svg icons, so you won't need to deploy iconfont locally anymore as well.

How do I extend antd's components?

If you need some features which should not be included in antd, try to extend antd's component with HOC. more

How do I fix dynamic styles while using a Content Security Policy (CSP)?

You can configure nonce by ConfigProvider.

When I set mode to DatePicker/RangePicker, why can I not select a year or month anymore?

In a real world development, you may need a YearPicker, MonthRangePicker or WeekRangePicker. You are trying to add mode to DatePicker/RangePicker expected to implement those pickers. However, the DatePicker/RangePicker cannot be selected and the panels won't close now.

• Reproduction link: https://codesandbox.io/s/dank-brook-v1csy
• Same issues：#15572, #16436, #11938, #11735, #11586, #10425, #11053

Like the explaination explains, this is because <DatePicker mode="year" /> does not equal the YearPicker, nor is <RangePicker mode="month" /> equal to MonthRangePicker. The mode property was added to support showing time picker panel in DatePicker in antd 3.0, which simply controls the displayed panel, and won't change the original date picking behavior of DatePicker/RangePicker (for instance you will still need to click date cell to finish selection in a DatePicker, whatever the mode is).

Likewise，disabledDate cannot work on year/month panels of <DatePicker mode="year/month" />, but only on cells of date panel.

Workaround

You can refer to this article or this article, using mode and onPanelChange to encapsulate a YearPicker or MonthRangePicker for your needs.

Or you can simply upgrade to antd@4.0, in which we added more XxxPickers to meet those requirements, and disabledDate could be effect on those pickers too.

message/notification/Modal.confirm lost styles when set prefixCls on ConfigProvider?

Static methods like message/notification/Modal.confirm are not using the same render tree as <Button />, but rendered to indepent DOM node created by ReactDOM.render, which cannot access React context from ConfigProvider. Consider two solutions here:

1. Replace original usages with message.useMessage, notification.useNotification and Modal.useModal.

2. Use message.config, notification.config and Modal.config to config prefixCls globally.

message.config({
  prefixCls: 'ant-message',
});
notification.config({
  prefixCls: 'ant-notification',
});
Modal.config({
  rootPrefixCls: 'ant',
});

How to spell Ant Design correctly?

• ✅ Ant Design: Capitalized with space, for the design language.
• ✅ antd: all lowercase, for the React UI library.
• ✅ ant.design：For ant.design website url.

Here are some typical wrong examples:

• ❌ AntD
• ❌ antD
• ❌ Antd
• ❌ ant design
• ❌ AntDesign
• ❌ antdesign
• ❌ Antdesign

Errors and Warnings

Here are some errors & warnings that you may encounter while using antd, although most of these are not actual bugs of antd itself.

Adjacent JSX elements must be wrapped in an enclosing tag

Check out this answer from StackOverflow, along with also reading React's documentation to solve this.

React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components)

Please make sure that you import antd's components correctly. Read the corresponding documentation of the antd's version which you use, and pay attention to typos.

rm is not recognized as an internal or external command

Please read this issue, or try Linux/Unix.

Failed propType: Invalid prop AAA of type BBB supplied to CCC, expected DDD. Check the render method of EEE.

Please read the corresponding documentation of the antd's version which you are currently using, and make sure that you pass values with correct type to antd's components,

Unknown option: xxx/package.json.presets

Check out this answer from Stack Overflow.

Invariant Violation: findComponentRoot(...): Unable to find element.

You may have imported React twice. Set React & ReactDOM as external, if you are using webpack, see #525. If you are using others (browserify, etc...), please read their documentation and find options which can set React & ReactDOM as external.
