## zh-CN
左边是按钮,右边是额外的相关功能菜单。可设置 `icon` 属性来修改右边的图标。
## en-US
A button is on the left, and a related functional menu is on the right. You can set the icon property to modify the icon of right.
```jsx
import { Menu, Dropdown, Button, message, Space, Tooltip } from 'antd';
import { DownOutlined, UserOutlined } from '@ant-design/icons';
function handleButtonClick(e) {
message.info('Click on left button.');
console.log('click left button', e);
}
function handleMenuClick(e) {
message.info('Click on menu item.');
console.log('click', e);
}
const menu = (
<Menu
onClick={handleMenuClick}
items={[
{
label: '1st menu item',
key: '1',
icon: <UserOutlined />,
},
{
label: '2nd menu item',
key: '2',
icon: <UserOutlined />,
},
{
label: '3rd menu item',
key: '3',
icon: <UserOutlined />,
},
]}
/>
);
export default () => (
<Space wrap>
<Dropdown.Button onClick={handleButtonClick} overlay={menu}>
Dropdown
</Dropdown.Button>
<Dropdown.Button overlay={menu} placement="bottom" icon={<UserOutlined />}>
Dropdown
</Dropdown.Button>
<Dropdown.Button onClick={handleButtonClick} overlay={menu} disabled>
Dropdown
</Dropdown.Button>
<Dropdown.Button
overlay={menu}
buttonsRender={([leftButton, rightButton]) => [
<Tooltip title="tooltip" key="leftButton">
{leftButton}
</Tooltip>,
React.cloneElement(rightButton, { loading: true }),
]}
>
With Tooltip
</Dropdown.Button>
<Dropdown overlay={menu}>
<Button>
Button <DownOutlined />
</Button>
</Dropdown>
</Space>
);
```
