Dialog

A modal component for displaying important content requiring user response.

Installation

Usage

Examples

Use the size prop to change the size of the dialog component.

Cover

Use the size="cover" prop to make the dialog component cover the entire screen while revealing a small portion of the page behind.

Fullscreen

Use the size="full" prop to make the dialog component take up the entire screen.

Responsive Size

Use responsive values for the size prop to make the dialog adapt to different screen sizes. We recommend using exact breakpoints values instead of using a base to ensure styles are properly contained.

Placements

Use the placement prop to change the placement of the dialog component.

Controlled

Use the open and onOpenChange prop to control the visibility of the dialog component.

Nested Dialogs

You can nest dialogs by using the Dialog.Root component inside another Dialog.Root component.

Initial Focus

Use the initialFocusEl prop to set the initial focus of the dialog component.

Inside Scroll

Use the scrollBehavior=inside prop to change the scroll behavior of the dialog when its content overflows.

Outside Scroll

Use the scrollBehavior=outside prop to change the scroll behavior of the dialog when its content overflows.

Motion Preset

Use the motionPreset prop to change the animation of the dialog component.

Alert Dialog

Set the role: "alertdialog" prop to change the dialog component to an alert dialog.

Non-Modal Dialog

We don't recommend using a non-modal dialog due to the accessibility concerns they present. In event you need it, here's what you can do:

  • set the modal prop to false
  • set pointerEvents to none on the Dialog.Positioner component
  • (optional)set the closeOnInteractOutside prop to false
