5	[{zh-CN 多个按钮组合} {en-US Multiple Buttons}]

zh-CN

按钮组合使用时，推荐使用1个主操作 + n 个次操作，3个以上操作时把更多操作放到 Dropdown.Button 中组合使用。

en-US

If you need several buttons, we recommend that you use 1 primary button + n secondary buttons, and if there are more than three operations, you can group some of them into Dropdown.Button.

import {
  Button, Menu, Dropdown, Icon,
} from 'antd';

function handleMenuClick(e) {
  console.log('click', e);
}

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

ReactDOM.render(
  <div>
    <Button type="primary">primary</Button>
    <Button>secondary</Button>
    <Dropdown overlay={menu}>
      <Button>
        Actions <Icon type="down" />
      </Button>
    </Dropdown>
  </div>,
  mountNode
);
