## 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}`.

```tsx
import {
  MenuFoldOutlined,
  MenuUnfoldOutlined,
  UploadOutlined,
  UserOutlined,
  VideoCameraOutlined,
} from '@ant-design/icons';
import { Layout, Menu } from 'antd';
import React, { useState } from 'react';

const { Header, Sider, Content } = Layout;

const App: React.FC = () => {
  const [collapsed, setCollapsed] = useState(false);

  return (
    <Layout>
      <Sider trigger={null} collapsible collapsed={collapsed}>
        <div className="logo" />
        <Menu
          theme="dark"
          mode="inline"
          defaultSelectedKeys={['1']}
          items={[
            {
              key: '1',
              icon: <UserOutlined />,
              label: 'nav 1',
            },
            {
              key: '2',
              icon: <VideoCameraOutlined />,
              label: 'nav 2',
            },
            {
              key: '3',
              icon: <UploadOutlined />,
              label: 'nav 3',
            },
          ]}
        />
      </Sider>
      <Layout className="site-layout">
        <Header className="site-layout-background" style={{ padding: 0 }}>
          {React.createElement(collapsed ? MenuUnfoldOutlined : MenuFoldOutlined, {
            className: 'trigger',
            onClick: () => setCollapsed(!collapsed),
          })}
        </Header>
        <Content
          className="site-layout-background"
          style={{
            margin: '24px 16px',
            padding: 24,
            minHeight: 280,
          }}
        >
          Content
        </Content>
      </Layout>
    </Layout>
  );
};

export default App;
```

```css
#components-layout-demo-custom-trigger .trigger {
  padding: 0 24px;
  font-size: 18px;
  line-height: 64px;
  cursor: pointer;
  transition: color 0.3s;
}

#components-layout-demo-custom-trigger .trigger:hover {
  color: #1890ff;
}

#components-layout-demo-custom-trigger .logo {
  height: 32px;
  margin: 16px;
  background: rgba(255, 255, 255, 0.3);
