# Dialog
A high-quality, unstyled Solid dialog component that opens on top of the entire page.
## Demo
### Tailwind
This example shows how to implement the component using Tailwind CSS.
```tsx
/* index.tsx */
import { Dialog } from 'base-ui-solid/dialog';
export default function ExampleDialog() {
return (
View notifications
);
}
```
## Usage guidelines
- **Dialog doesn't support gestures:** Use [Drawer](/solid/components/drawer.md) 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:
```jsx title="Anatomy"
import { Dialog } from 'base-ui-solid/dialog';
;
```
## Examples
### State
By default, Dialog is an uncontrolled component that manages its own state.
```tsx title="Uncontrolled dialog"
OpenExample dialogClose
```
Use `open` and `onOpenChange` props 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.
```tsx title="Controlled dialog"
import { createSignal } from 'solid-js';
const [open, setOpen] = createSignal(false);
return (
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 `createEffect` when reacting to state changes.
```tsx title="Running code when dialog state changes"
{
// Do stuff when the dialog is closed
if (!open) {
doStuff();
}
// Set the new state
setOpen(open);
}}
>
```
### 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.
## Demo
### Tailwind
This example shows how to implement the component using Tailwind CSS.
```tsx
/* index.tsx */
import { createSignal } from 'solid-js';
import type { JSX } from '@solidjs/web';
import { Dialog } from 'base-ui-solid/dialog';
import { Menu } from 'base-ui-solid/menu';
export default function ExampleDialog() {
const [dialogOpen, setDialogOpen] = createSignal(false);
return (
<>
Playlist PlayShare
{/* Open the dialog when the menu item is clicked */}
setDialogOpen(true)}>
Details…
{/* Control the dialog state */}
Playlist details
This playlist contains 24 songs and was last updated today.

Close
);
}
function CaretDownIcon(props: JSX.IntrinsicElements['svg']) {
return (
);
}
```
### 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.
## Demo
### Tailwind
This example shows how to implement the component using Tailwind CSS.
```tsx
/* index.tsx */
import { Dialog } from 'base-ui-solid/dialog';
export default function ExampleDialog() {
return (
View notifications
Notifications

Close
);
}
```
### 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.

### Tailwind
This example shows how to implement the component using Tailwind CSS.
```tsx
/* index.tsx */
import { createSignal, createUniqueId } from 'solid-js';
import { AlertDialog } from 'base-ui-solid/alert-dialog';
import { Dialog } from 'base-ui-solid/dialog';
export default function ExampleDialog() {
const [dialogOpen, setDialogOpen] = createSignal(false);
const [confirmationOpen, setConfirmationOpen] = createSignal(false);
const [textareaValue, setTextareaValue] = createSignal('');
const titleId = createUniqueId();
return (
{
// Show the close confirmation if there’s text in the textarea
if (!open && textareaValue()) {
setConfirmationOpen(true);
} else {
// Reset the text area value
setTextareaValue('');
// Open or close the dialog normally
setDialogOpen(open);
}
}}
