Examples

Align Item With Trigger

Use the position prop on SelectContent to control alignment. When position="item-aligned" (default), the popup positions so the selected item appears over the trigger. When position="popper", the popup aligns to the trigger edge.

Groups

Use SelectGroup, SelectLabel, and SelectSeparator to organize items.

Scrollable

A select with many items that scrolls.

Disabled

Invalid

Add the data-invalid attribute to the Field component and the aria-invalid attribute to the SelectTrigger component to show an error state.

tsx

<Field data-invalid>
  <FieldLabel>Fruit</FieldLabel>
  <SelectTrigger aria-invalid>
    <SelectValue />
  </SelectTrigger>
</Field>

To enable RTL support in shadcn/ui, see the RTL configuration guide.
