## zh-CN

要使用自定义触发器，可以设置 `trigger={null}` 来隐藏默认设定。

## en-US

If you want to use a customized trigger, you can hide the default one by setting `trigger={null}`.

````jsx
import { Layout, Menu, Icon } from 'antd';
const { Header, Sider, Content } = Layout;

class SiderDemo extends React.Component {
  state = {
    collapsed: false,
  };

    this.setState({
      collapsed: !this.state.collapsed,
