Examples

Custom selected value

By default the selected item's text will be rendered when selected. Sometimes you may need to render something different. You can control the select and pass children instead.

import { Select } from "@ngrok/mantle/select";

<Select.Root value={value} onValueChange={setValue}>
	<Select.Trigger className="w-[180px]">
		<Select.Value placeholder="Select a fruit">
			{value === "apple" ? <>🍎 Apple!</> : <>🍑 Peach!</>}
		</Select.Value>
	</Select.Trigger>
	<Select.Content width="trigger">
		<Select.Item value="apple">Apple</Select.Item>
		<Select.Item value="peach">Peach</Select.Item>
	</Select.Content>
</Select.Root>

API Reference

The Select components are built on top of Radix Select.

Displays a list of options for the user to pick from—triggered by a button.

All props from Radix Select.Root, plus:

PropTypeDefaultDescription
onValueChange
(value: string) => void
—

Event handler called when the value changes.

validation
  • error
  • success
  • warning
  • false
  • () => "error" | "success" | "warning" | false
—

Use the validation prop to show if the select trigger has a specific validation status. This will change the border and outline of the select trigger.

The false type is useful when using short-circuiting logic so that you don't need to use a ternary with undefined.

Setting validation to error also sets aria-invalid.

Select.Trigger
