Are you going to provide Sass/Stylus(etc.) style file?

No plan, but you can convert Less to Sass/Stylus(etc.) with tools that you can find on Google.

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

This has been fixed since 3.11.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)

Select Dropdown DatePicker TimePicker Popover Popconfirm scrolls 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)

How do I modify the default theme of Ant Design?

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

Would you supply other themes?

No, we follow Ant Design specification. https://github.com/ant-design/ant-design/issues/1241

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

You can override its style but we don't recommend doing so. antd is not only a set of React components but also a design specification.

How to replace Moment.js to Day.js to reduce bundle size？

Please refer to Replace Moment.js.

It doesn't work when I change defaultValue dynamically.

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

Why modify props in mutable way not trigger component update?

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

I set the value of Input/Select(etc.), and then it 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 develop a complete background application, we override some global styles for styling convenience, and it can't be removed now. 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.

Long live the Girl Friend Wall! And try cnpm.

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

Yes, please install antd with npm or yarn.

message and notification is lower case, but other components are capitalized. Typo?

No, as message is just a function, not a React Component.

antd doesn't work well in mobile.

Please check And Design Mobile for details. antd has not been optimized to do so. You may try react-component, those repositories which start with 'm-' 'rn-' are 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, 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 are using svg icon, so you don't need to deploy iconfont locally anymore.

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 style when open Content Security Policy (CSP)?

You can configure nonce by ConfigProvider.

When I set mode to DatePicker/RangePicker, I cannot select 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 here, that is because <DatePicker mode="year" /> do not equal to YearPicker, <RangePicker mode="month" /> do not equal to MonthRangePicker either. The mode property was added to support showing time picker panel in DatePicker in antd 3.0, which simply control the displayed panel and won't change the original date picking behavior of DatePicker/RangePicker (for instance you still need to click date cell to finish selection in a DatePicker, whatever the mode is).

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 wait for our antd@4.0, in which we are planing (already) to add more XxxPickers for those requirments.

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: 'my-message',
});
notification.config({
  prefixCls: 'my-notification',
});
Modal.config({
  prefixCls: 'my-modal',
});

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

Adjacent JSX elements must be wrapped in an enclosing tag
