Key features:
- Keyboard navigation with arrow keys

- Click outside closes dropdown
- Support for icons and separators
- Multiple placement options
- Nested submenus

A simple dropdown with action items and a separator before destructive action.

Add icons to menu items for visual context. Use an icon-only trigger with visually-hidden text for accessibility.

Listen for dropdown events to respond to user actions.

document.querySelector('drop-down').addEventListener('select', (e) => { console.log('Selected:', e.detail.value);}); dropdown.addEventListener('open', () => { console.log('Dropdown opened');}); dropdown.addEventListener('close', () => { console.log('Dropdown closed');});Usage Notes
