Structure

	<script lang="ts">
	import { Toolbar } from "bits-ui";
</script>
 
<Toolbar.Root>
	<Toolbar.Group>
		<Toolbar.GroupItem />
	</Toolbar.Group>
	<Toolbar.Link />
	<Toolbar.Button />
</Toolbar.Root>

Managing Value State

Bits UI offers several approaches to manage and synchronize the component's value state, catering to different levels of control and integration needs.

1. Two-Way Binding

For seamless state synchronization, use Svelte's bind:value directive. This method automatically keeps your local state in sync with the component's internal state.

	<script lang="ts">
	import { Toolbar } from "bits-ui";
	let myValue = $state("");
</script>
 
<button onclick={() => (myValue = "item-1")}> Press item 1 </button>
 
<Toolbar.Root>
	<Toolbar.Group type="single" bind:value={myValue}>
		<!-- ... -->
	</Toolbar.Group>
</Toolbar.Root>

Key Benefits

  • Simplifies state management
  • Automatically updates myValue when the internal state changes (e.g., via clicking on an item)
  • Allows external control (e.g., toggling an item via a separate button)

2. Change Handler

For more granular control or to perform additional logic on state changes, use the onValueChange prop. This approach is useful when you need to execute custom logic alongside state updates.

	<script lang="ts">
	import { Toolbar } from "bits-ui";
	let myValue = $state("");
</script>
 
<Toolbar.Root>
	<Toolbar.Group
		type="single"
		value={myValue}
		onValueChange={(v) => {
			myValue = v;
			// additional logic here.
		}}
	>
		<!-- ... -->
	</Toolbar.Group>
</Toolbar.Root>

Use Cases

  • Implementing custom behaviors on value change
  • Integrating with external state management solutions
  • Triggering side effects (e.g., logging, data fetching)

3. Fully Controlled

For complete control over the component's state, use a Function Binding to manage the value state externally.

	<script lang="ts">
	import { Toolbar } from "bits-ui";
	let myValue = $state("");
</script>
 
<Toolbar.Root>
	<Toolbar.Group type="single" bind:value={() => myValue, (newValue) => (myValue = newValue)}>
		<!-- ... -->
	</Toolbar.Group>
</Toolbar.Root>

When to Use

  • Implementing complex logic
  • Coordinating multiple UI elements
  • Debugging state-related issues
