A versatile menu for navigation.

When To Use

Navigation is an important part of any website, as a good navigation setup allows users to move around the site quickly and efficiently. Ant Design offers two navigation options: top and side. Top navigation provides all the categories and functions of the website. Side navigation provides the multi-level structure of the website.

More layouts with navigation: Layout.

Notes for developers

  • Menu is rendered as a ul element, so it only supports li and script-supporting elements as children nodes。Your customized node should be wrapped by Menu.Item.
  • Menu needs to collect its node structure, so its children should be Menu.* or encapsulated HOCs.

Usage upgrade after 4.20.0

import Alert from '../alert';
ReactDOM.render(<Alert message="After version 4.20.0, we provide a simpler usage <Menu items={[...]} /> with better perfermance and potential of writing simpler code style in your applications. Meanwhile, we deprecated the old usage in browser console, we will remove it in antd 5.0." />, mountNode);
// works when >=4.20.0, recommended ✅
const items = [
  { label: 'item 1' },
  { label: 'item 2' },
  {
    label: 'sub menu',
    children: [{ label: 'item 3' }],
  },
];
return <Menu items={items} />;

// works when <4.20.0, deprecated when >=4.20.0 🙅🏻‍♀️
<Menu>
  <Menu.Item>item 1</Menu.Item>
  <Menu.Item>item 2</Menu.Item>
  <Menu.SubMenu title="sub menu">
    <Menu.Item>item 3</Menu.Item>
  </Menu.SubMenu>
</Menu>;

The legacy demo code for version <4.20.0 could be found at https://github.com/ant-design/ant-design/tree/4.19.5/components/menu/demo.

FAQ

Why will Menu's children be rendered twice?

Menu collects structure info with twice-render to support HOC usage. Merging into one render may cause the logic to become much more complex. Contributions to help improve the collection logic are welcomed.
