  }
]
</script>

Best Practices

1. Use appropriate trigger: Choose hover or click based on use case

   • Hover: Quick access menus
   • Click: Action menus, forms
   • Manual: Context menus

2. Unique keys: Ensure each option has a unique key

   { label: 'Edit', key: 'edit' }
   

3. Group related options: Use dividers and groups

   [
     { label: 'Edit', key: 'edit' },
     { type: 'divider', key: 'd1' },
     { label: 'Delete', key: 'delete' }
   ]
   

4. Disable unavailable options: Use disabled for unavailable actions

   { label: 'Delete', key: 'delete', disabled: true }
   

5. Context menu pattern: Always handle clickoutside for manual triggers

   <n-dropdown
     trigger="manual"
     :on-clickoutside="() => show = false"
   />
   

6. Keyboard accessibility: Keep keyboard enabled for accessibility

   <n-dropdown keyboard :options="options">
   

7. Icons for clarity: Add icons to improve visual recognition

   { label: 'Delete', key: 'delete', icon: () => h(TrashIcon) }
