### Button Integration

## Button Variants

Command bars support different button configurations:

### Standard Command Button
```html
<button type="button" class="hoo-buttoncmd">
  <div class="hoo-buttoncmd-icon"><!-- Icon --></div>
  <div class="hoo-buttoncmd-label">Label</div>
</button>
```

### Command Button with Dropdown
```html
<button type="button" class="hoo-buttoncmd">
  <div class="hoo-buttoncmd-icon"><!-- Icon --></div>
  <div class="hoo-buttoncmd-label">Label</div>
  <div class="hoo-buttoncmd-caret"><!-- Chevron --></div>
</button>
```

### Icon-Only Command Button
```html
<button type="button" class="hoo-buttoncmd">
  <div class="hoo-buttoncmd-icon"><!-- Icon --></div>
</button>
```

## Usage Guidelines

- Use `role="toolbar"` on the command bar container for accessibility
- Group related commands together logically
- Place primary actions on the left, secondary actions on the right
- Include dropdown carets only when the button has a dropdown menu
- Provide meaningful labels and icons for all command buttons
- Consider responsive behavior for mobile devices
- Test keyboard navigation through toolbar buttons

## Responsive Considerations

- Command bars should adapt gracefully to smaller screens
- Consider using overflow menus for limited space scenarios
- Icons may be more important than labels on narrow screens
- Maintain proper touch targets (minimum 44px) on mobile devices
