### Other Components
- `Sidebar.Header` - Container for the top section of the sidebar

## Accessibility
- Proper semantic structure with `<ul>` and `<li>` elements for navigation lists
- Navigation items support `aria-current="page"` for active state
- Toggle button includes descriptive `aria-label`
- Focus management for keyboard navigation
- Section titles are properly separated from navigation items
- ARIA roles enhance screen reader announcements
## Custom Toggle Example
You can replace the default toggle button with a custom component:
```jsx
import { Sidebar } from '@react-beauty/ui-sidebar';
import { Icon } from '@react-beauty/ui-icon';
import { Button } from '@react-beauty/ui-button';
import { useState } from 'react';
function App() {
const [isExpanded, setIsExpanded] = useState(true);
return (
<div style={{
display: 'flex',
overflow: 'hidden',
position: 'relative'
}}>
<Sidebar isExpanded={isExpanded} onExpandedChange={setIsExpanded}>
<Sidebar.Header>
<div style={{ display: 'flex', alignItems: 'center', gap: '12px' }}>
<span style={{
width: '32px',
height: '32px',
backgroundColor: 'var(--colors-main-picollo)',
borderRadius: '4px',
display: 'flex',
alignItems: 'center',
justifyContent: 'center',
fontWeight: 'bold'
}}>
RB
</span>
{isExpanded && (
<span style={{ fontWeight: 'bold' }}>React Beauty</span>
)}
</div>
</Sidebar.Header>
<Sidebar.Body>
{/* Sidebar content */}
</Sidebar.Body>
<Sidebar.Footer>
<Button
size="sm"
variant="outline"
onClick={() => setIsExpanded(!isExpanded)}
>
{isExpanded ? 'Collapse' : 'Expand'}
</Button>
</Sidebar.Footer>
</Sidebar>
<div style={{
padding: '24px'
}}>
{/* Main content */}
</div>
</div>
);
}You can initialize the sidebar in a collapsed state:
import { Sidebar } from '@react-beauty/ui-sidebar';
import { Icon } from '@react-beauty/ui-icon';
import { useState } from 'react';
function App() {
// Initialize with collapsed state
const [isExpanded, setIsExpanded] = useState(false);
return (
<div style={{
display: 'flex',
overflow: 'hidden',
position: 'relative'
}}>
<Sidebar isExpanded={isExpanded} onExpandedChange={setIsExpanded}>
<Sidebar.Header>
<div style={{ display: 'flex', alignItems: 'center', gap: '12px' }}>
<span style={{
width: '32px',
height: '32px',
backgroundColor: 'var(--colors-main-picollo)',
borderRadius: '4px',
display: 'flex',
alignItems: 'center',
justifyContent: 'center',
fontWeight: 'bold'
}}>
RB
</span>
{isExpanded && (
<span style={{ fontWeight: 'bold' }}>React Beauty</span>
)}
</div>
<Sidebar.ToggleButton />
</Sidebar.Header>
<Sidebar.Body>
{/* Sidebar content */}
</Sidebar.Body>
<Sidebar.Footer>
<Sidebar.Section>
<Sidebar.ItemList>
<Sidebar.Item
icon={<Icon name="genericLogOut" />}
onClick={() => {}}
>
Logout
</Sidebar.Item>
</Sidebar.ItemList>
</Sidebar.Section>
</Sidebar.Footer>
</Sidebar>
<div style={{
padding: '24px'
}}>
<h1>Main Content Area</h1>
<p>
This is the main content that adjusts based on the sidebar width.
</p>
<p>The sidebar starts collapsed in this example.</p>
</div>
</div>
);
}
