## Usage
|
|
|
|
```tsx showLineNumbers
|
|
import {
|
|
Select,
|
|
SelectContent,
|
|
SelectItem,
|
|
SelectTrigger,
|
|
SelectValue,
|
|
} from "@/components/ui/select"
|
|
```
|
|
|
|
```tsx showLineNumbers
|
|
<Select>
|
|
<SelectTrigger className="w-[180px]">
|
|
<SelectValue placeholder="Theme" />
|
|
</SelectTrigger>
|
|
<SelectContent>
|
|
<SelectItem value="light">Light</SelectItem>
|
|
<SelectItem value="dark">Dark</SelectItem>
|
|
<SelectItem value="system">System</SelectItem>
|
|
</SelectContent>
|
|
</Select>
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Align Item With Trigger
|
|
|
|
Use `alignItemWithTrigger` on `SelectContent` to control whether the selected item aligns with the trigger. When `true` (default), the popup positions so the selected item appears over the trigger. When `false`, the popup aligns to the trigger edge.
|
|
|
|
<ComponentPreview styleName="base-nova" name="select-align-item" />
|
|
|
|
### Groups
|
|
|
|
Use `SelectGroup`, `SelectLabel`, and `SelectSeparator` to organize items.
|
|
|
|
<ComponentPreview styleName="base-nova" name="select-groups" />
|
|
|
|
### Scrollable
|
|
|
|
A select with many items that scrolls.
|
|
|
|
<ComponentPreview styleName="base-nova" name="select-scrollable" />
|
|
|
|
### Disabled
|
|
|
|
<ComponentPreview styleName="base-nova" name="select-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 showLineNumbers /data-invalid/ /aria-invalid/
|
|
<Field data-invalid>
|
|
<FieldLabel>Fruit</FieldLabel>
|
|
<SelectTrigger aria-invalid>
|
|
<SelectValue />
|
|
</SelectTrigger>
|
|
</Field>
|
|
```
|
|
|
|
<ComponentPreview styleName="base-nova" name="select-invalid" />
|
|
|
