|
||
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](/components/layout).
|
||
|
||
## Notes for developers
|
||
|
||
- Menu is rendered as a `ul` element, so it only supports [`li` and `script-supporting` elements](https://html.spec.whatwg.org/multipage/grouping-content.html#the-ul-element) 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
|
||
|
||
```__react
|
||
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);
|
||
```
|
||
|
||
```jsx
|
||
// works when >=4.20.0, recommended ✅
|
||
const items = [
|
||
{ label: 'item 1', key: 'item-1' }, // remember to pass the key prop
|
||
{ label: 'item 2', key: 'item-2' }, // which is required
|
||
{
|
||
label: 'sub menu',
|
||
key: 'submenu',
|
||
children: [{ label: 'item 3', key: 'submenu-item-1' }],
|
||
},
|
||
];
|
||
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>;
|
||
```
|

## FAQ
|
||
|
||
### Why will Menu's children be rendered twice?
|
||
|
||
Menu collects structure info with [twice-render](https://github.com/react-component/menu/blob/f4684514096d6b7123339cbe72e7b0f68db0bce2/src/Menu.tsx#L543) 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.
