# Dialog
A popup that opens on top of the entire page.
```svelte
View notifications
Notifications
You are all caught up. Good job!
Close
```
## Usage guidelines
- **Dialog doesn't support gestures:** Use [Drawer](/components/drawer) when you need gesture support or snap points. A panel that slides in from the edge of the screen and doesn't need gesture support is a positioned Dialog.
## Anatomy
Import the component and assemble its parts:
```svelte
```
## Examples
### State
By default, Dialog is an uncontrolled component that manages its own state.
```svelte
OpenExample dialogClose
```
Use `bind:open` if you need to access or control the state of the dialog.
For example, you can control the dialog state in order to open it imperatively from another place in your app.
```svelte
Open
```
It's also common to use `onOpenChange` if your app needs to do something when the dialog is closed or opened. This is recommended over `$effect` when reacting to state changes. The callback runs before the state changes, and the binding sets the new state, so there is no setter to call.
```svelte
{
if (!nextOpen) {
doStuff();
}
}}
>
...
```
### Open from a menu
In order to open a dialog using a menu, control the dialog state and open it imperatively using the `onclick` handler on the menu item. Bind `open` on `` and set it from that handler.
```svelte
Playlist
PlayShare (dialogOpen = true)}>Details…
Playlist details
This playlist contains 24 songs and was last updated today.
Close
```
### Nested dialogs
You can nest dialogs within one another normally.
Use the `[data-nested-dialog-open]` selector and the `var(--nested-dialogs)` CSS variable to customize the styling of the parent dialog. Backdrops of the child dialogs won't be rendered so that you can present the parent dialog in a clean way behind the one on top of it.

### Close confirmation
This example shows a nested confirmation dialog that opens if the text entered in the parent dialog is going to be discarded.
To implement this, both dialogs should be controlled. The confirmation dialog may be opened when `onOpenChange` callback of the parent dialog receives a request to close. This way, the confirmation is automatically shown when the user clicks the backdrop, presses the Esc key, or clicks a close button. Call `eventDetails.cancel()` in that callback to keep the parent dialog open while the confirmation shows.
```svelte
{
if (!open && textareaValue) {
eventDetails.cancel();
confirmationOpen = true;
} else {
textareaValue = '';
}
}}

```
### Custom focus management
You can control where the focus goes when the dialog opens and closes using the `initialFocus` and `finalFocus` props on the `` component.
You can also set these props to `false` to prevent focus from moving when the dialog opens or closes, or to a function that returns the element to focus based on the interaction type. There is no ref object: pass an element, or a function that returns the element.
```svelte
```
### Outside scroll dialog
The dialog can be made scrollable by using `` as an outer scrollable container for `` while the popup can extend past the bottom edge. The scrollable area uses the [Scroll Area component](/components/scroll-area) to provide custom scrollbars.
```svelte
Open dialog
{
popupEl = node;
}}
initialFocus={() => popupEl}
class="outline-0 relative mx-auto my-16 flex w-[min(40rem,calc(100vw-2rem))] flex-col gap-4 bg-white dark:bg-neutral-950 p-4 text-neutral-950 dark:text-white border border-neutral-950 dark:border-white shadow-[0.25rem_0.25rem_0] shadow-black/12 dark:shadow-none transition-[translate] duration-[700ms] ease-[cubic-bezier(0.45,1.005,0,1.005)] data-starting-style:translate-y-[100dvh] data-ending-style:translate-y-[max(100dvh,100%)] data-ending-style:duration-[350ms] data-ending-style:ease-[cubic-bezier(0.375,0.015,0.545,0.455)] motion-reduce:transition-none"

{item.body}
{/each}

```
### Inside scroll dialog
The dialog can be made scrollable by making an inner container scrollable while the popup stays fully on screen. `` is used as a positioning container for ``, while an inner scrollable area is created using the [Scroll Area component](/components/scroll-area).
```svelte
Open dialog
Dialog
This layout keeps the popup fully on screen while allowing its content to scroll.
{#each CONTENT_SECTIONS as item (item.title)}
{item.title}
{item.body}
{/each}
Close
```
### Placing elements outside the popup
When adding elements that should appear "outside" the colored popup area, continue to place them inside ``, but create a child element that has the popup styles. This ensures they are kept in the tab order and announced correctly by screen readers.
`` has `pointer-events: none`, while inner content (the colored popup and close button) has `pointer-events: auto` so clicks on the backdrop continue to be registered.
```svelte
Open dialog
```
### Detached triggers
A dialog can be controlled by a trigger located either inside or outside the `` component.
For simple, one-off interactions, place the `` inside ``, as shown in the example at the top of this page.
However, if defining the dialog's content next to its trigger is not practical, you can use a detached trigger.
This involves placing the `` outside of `` and linking them with a `handle` created by the `Dialog.createHandle()` function.
The imperative methods on the handle, such as `open()` and `openWithPayload()`, require a `` using the same handle to be mounted.
Calls made while no root is attached to the handle — before one mounts, or after it unmounts — are ignored. Each time a root mounts, it starts from fresh state: a call made while no root was attached is not replayed, and no open state carries over from a previous mount.
```svelte
Open...
```
```svelte
View notifications
Notifications
You are all caught up. Good job!
Close
```
### Multiple triggers
A single dialog can be opened by multiple trigger elements.
You can achieve this by using the same `handle` for several detached triggers, or by placing multiple `` components inside a single ``.
```svelte
Trigger 1Trigger 2
...
```
```svelte
Trigger 1Trigger 2...
```
The dialog can render different content depending on which trigger opened it.
This is achieved by passing a `payload` to the `` and reading it from the `children` snippet of ``, which receives `{ payload }`.
The payload can be strongly typed by providing a type argument to the `createHandle()` function:
```svelte
Trigger 1Trigger 2
{#snippet children({ payload })}
Dialog
{#if payload !== undefined}
This has been opened by {payload.text}
{/if}
{/snippet}
```
### Controlled mode with multiple triggers
You can control the dialog's open state externally using the `open` and `onOpenChange` props on ``.
This allows you to manage the dialog's visibility based on your application's state.
When using multiple triggers, you have to manage which trigger is active with the `triggerId` prop on `` and the `id` prop on each ``.
Note that there is no separate `onTriggerIdChange` prop.
Instead, the `onOpenChange` callback receives an additional argument, `eventDetails`, which contains the trigger element that initiated the state change.
```svelte
{/snippet}
```
## API reference
### Root
Groups all parts of the dialog. Doesn't render its own HTML element.
**Dialog.Root Props:**
| Prop | Type | Default | Description |
| :--- | :--- | :------ | :---------- |
| open | `boolean` | `false` | Whether the dialog is open. Use `bind:open` to share it with the parent. A value passed without `bind:` holds until the parent changes it. |
| modal | `boolean \| 'trap-focus'` | `true` | `true` traps focus, locks page scroll, and blocks outside pointer interaction. `false` leaves the rest of the page usable. `'trap-focus'` traps focus without locking scroll or outside pointers. |
| onOpenChange | `(open: boolean, eventDetails: DialogChangeEventDetails) => void` | - | Called before the open state changes. Call `eventDetails.cancel()` to veto it. |
| onOpenChangeComplete | `(open: boolean) => void` | - | Called after the open or close animation finishes. |
| disablePointerDismissal | `boolean` | `false` | Do not close on outside presses. Non-modal dialogs also stay open when focus moves outside. |
| handle | `DialogHandle` | - | Connects detached triggers. Create one with `Dialog.createHandle()`. |
| triggerId | `string \| null` | `null` | Id of the trigger that owns the dialog. Use `bind:triggerId` to share it with the parent. Pass it with an initial `open` to name the trigger the dialog starts from. An id written by a trigger press resets to `null` once the popup unmounts. |
| children | `Snippet<[{ payload: Payload \| undefined }]>` | - | |
### Trigger
A button that opens the dialog. Renders a `
