用法

import {
  Select,
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@/components/ui/select"

<Select>
  <SelectTrigger className="w-[180px]">
    <SelectValue placeholder="Theme" />
  </SelectTrigger>
  <SelectContent>
    <SelectGroup>
      <SelectItem value="light">Light</SelectItem>
      <SelectItem value="dark">Dark</SelectItem>
      <SelectItem value="system">System</SelectItem>
    </SelectGroup>
  </SelectContent>
</Select>

Composition

Use the following composition to build a Select:

Select
├── SelectTrigger
│   └── SelectValue
└── SelectContent
    ├── SelectGroup
    │   ├── SelectLabel
    │   ├── SelectItem
    │   └── SelectItem
    ├── SelectSeparator
    └── SelectGroup
        ├── SelectLabel
        ├── SelectItem
        └── SelectItem

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.

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