Managing Placeholder State

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

1. Two-Way Binding

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

	<script lang="ts">
	import { DatePicker } from "bits-ui";
	import { CalendarDateTime } from "@internationalized/date";
	let myPlaceholder = $state(new CalendarDateTime(2024, 8, 3, 12, 30));
</script>
 
<button onclick={() => (myPlaceholder = new CalendarDate(2024, 8, 3))}>
	Set placeholder to August 3rd, 2024
</button>
 
<DatePicker.Root bind:placeholder={myPlaceholder}>
	<!-- ... -->
</DatePicker.Root>

Key Benefits

  • Simplifies state management
  • Automatically updates myPlaceholder when the internal state changes
  • Allows external control (e.g., changing the placeholder via a separate button/programmatically)

2. Change Handler

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

	<script lang="ts">
	import { DatePicker } from "bits-ui";
	import { CalendarDateTime } from "@internationalized/date";
	let myPlaceholder = $state(new CalendarDateTime(2024, 8, 3, 12, 30));
</script>
 
<DatePicker.Root
	placeholder={myPlaceholder}
	onPlaceholderChange={(p) => {
		placeholder = p;
	}}
>
	<!-- ... -->
</DatePicker.Root>

Use Cases

  • Implementing custom behaviors on placeholder 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 placeholder state, use the controlledPlaceholder prop. This approach requires you to manually manage the state, giving you full control over when and how the component responds to change events.

To implement controlled state:

  1. Set the controlledPlaceholder prop to true on the DatePicker.Root component.
  2. Provide a placeholder prop to DatePicker.Root, which should be a variable holding the current state.
  3. Implement an onPlaceholderChange handler to update the state when the internal state changes.
	<script lang="ts">
	import { DatePicker } from "bits-ui";
	let myPlaceholder = $state();
</script>
 
<DatePicker.Root
	controlledPlaceholder
	placeholder={myPlaceholder}
	onPlaceholderChange={(p) => (myPlaceholder = p)}
>
	<!-- ... -->
</DatePicker.Root>

When to Use

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

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 { DatePicker } from "bits-ui";
	import { CalendarDateTime } from "@internationalized/date";
	let myValue = $state(new CalendarDateTime(2024, 8, 3, 12, 30));
</script>
 
<button onclick={() => (myValue = myValue.add({ days: 1 }))}> Add 1 day </button>
<DatePicker.Root bind:value={myValue}>
	<!-- ... -->
</DatePicker.Root>

Key Benefits

  • Simplifies state management
  • Automatically updates myValue when the internal state changes
  • Allows external control (e.g., changing the value via a separate button/programmatically)

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 { DatePicker } from "bits-ui";
	import { CalendarDateTime } from "@internationalized/date";
	let myValue = $state(new CalendarDateTime(2024, 8, 3, 12, 30));
</script>
 
<DatePicker.Root
	value={myValue}
	onValueChange={(v) => {
		value = v.set({ hour: v.hour + 1 });
	}}
>
	<!-- ... -->
</DatePicker.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 value state, use the controlledValue prop. This approach requires you to manually manage the state, giving you full control over when and how the component responds to change events.

To implement controlled state:

  1. Set the controlledValue prop to true on the DatePicker.Root component.
  2. Provide a value prop to DatePicker.Root, which should be a variable holding the current state.
  3. Implement an onValueChange handler to update the state when the internal state changes.
	<script lang="ts">
	import { DatePicker } from "bits-ui";
	let myValue = $state();
</script>
 
<DatePicker.Root controlledValue value={myValue} onValueChange={(v) => (myValue = v)}>
	<!-- ... -->
</DatePicker.Root>

When to Use

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

Managing Open State

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

1. Two-Way Binding

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

	<script lang="ts">
	import { DatePicker } from "bits-ui";
	let isOpen = $state(false);
</script>
 
<button onclick={() => (isOpen = true)}>Open DatePicker</button>
 
<DatePicker.Root bind:open={isOpen}>
	<!-- ... -->
</DatePicker.Root>

Key Benefits

  • Simplifies state management
  • Automatically updates isOpen when the picker closes (e.g., via escape key)
  • Allows external control (e.g., opening via a separate button)

2. Change Handler

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

	<script lang="ts">
	import { DatePicker } from "bits-ui";
	let isOpen = $state(false);
</script>
 
<DatePicker.Root
	open={isOpen}
	onOpenChange={(open) => {
		isOpen = open;
		// additional logic here.
	}}
>
	<!-- ... -->
</DatePicker.Root>

Use Cases

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

3. Fully Controlled

For complete control over the component's open state, use the controlledOpen prop. This approach requires you to manually manage the open state, giving you full control over when and how the dialog responds to open/close events.

To implement controlled state:

  1. Set the controlledOpen prop to true on the DatePicker.Root component.
  2. Provide an open prop to DatePicker.Root, which should be a variable holding the current state.
  3. Implement an onOpenChange handler to update the state when the internal state changes.
	<script lang="ts">
	import { DatePicker } from "bits-ui";
 
	let myOpen = $state(false);
</script>
 
<DatePicker.Root controlledOpen open={myOpen} onOpenChange={(o) => (myOpen = o)}>
	<!-- ... -->
</DatePicker.Root>

When to Use

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

Customization

The DatePicker component is made up of three other Bits UI components: Date Field, Calendar, and Popover.

You can check out the documentation for each of these components to learn more about their customization options, each of which can be used to customize the DatePicker component.
