## en-US

An event will be triggered when you click menu items, in which you can make different operations according to item's key.

```jsx
import { Menu, Dropdown, message } from 'antd';
import { DownOutlined } from '@ant-design/icons';

const onClick = ({ key }) => {
  message.info(`Click on item ${key}`);
};

const menu = (
  <Menu onClick={onClick}>
    <Menu.Item key="1">1st menu item</Menu.Item>
    <Menu.Item key="2">2nd memu item</Menu.Item>
    <Menu.Item key="3">3rd menu item</Menu.Item>
  </Menu>
);

ReactDOM.render(
  <Dropdown overlay={menu}>
    <a className="ant-dropdown-link" href="#">
      Hover me, Click menu item <DownOutlined />
    </a>
  </Dropdown>,
  mountNode,
);
```
