Picker composes Select: a SelectTrigger showing the current value and a SelectContent popup with the options. The selected option shows a check mark.

Use it to choose one value from a short or grouped list in a form.

Usage

import { Picker, PickerGroup, PickerItem, PickerSeparator } from "@/components/patterns/picker"

<PickerDemo />

List PickerItems as children, optionally inside PickerGroups separated by PickerSeparator. The picker collects the items from its children to show the selected label, or you can pass items directly.

Use it uncontrolled with defaultValue, or controlled with value and onValueChange. placeholder shows while nothing is selected.

Examples

States

A small picker with a value, an invalid picker and a disabled picker.

The popup fades in and out, and respects the system reduce motion setting.
On iOS the popup renders in a full-window overlay so it appears above native screens.
