  • Ask users to confirm a consequential or destructive action, such as deleting a record.
  • Require a deliberate response before continuing or discarding unsaved work.
  • Present a short, blocking decision with clear action and cancel controls.

Examples

Confirm deletion

Use a clear warning and an explicit cancel option before removing a project.

confirm-deletion.tsx
import {  AlertDialog,  AlertDialogAction,  AlertDialogCancel,  AlertDialogContent,  AlertDialogDescription,  AlertDialogFooter,  AlertDialogHeader,  AlertDialogTitle,  AlertDialogTrigger,} from "@/components/ui/alert-dialog"export function DeleteProjectDialog() {  return (    <AlertDialog>      <AlertDialogTrigger>Delete project</AlertDialogTrigger>      <AlertDialogContent>        <AlertDialogHeader>          <AlertDialogTitle>Delete this project?</AlertDialogTitle>          <AlertDialogDescription>            This action cannot be undone. The project and its data will be removed.          </AlertDialogDescription>        </AlertDialogHeader>        <AlertDialogFooter>          <AlertDialogCancel>Cancel</AlertDialogCancel>          <AlertDialogAction>Delete project</AlertDialogAction>        </AlertDialogFooter>      </AlertDialogContent>    </AlertDialog>  )}

Discard unsaved edits

Warn users before they leave an editor with changes they have not saved.

discard-unsaved-edits.tsx
import {  AlertDialog,  AlertDialogAction,  AlertDialogCancel,  AlertDialogContent,  AlertDialogDescription,  AlertDialogFooter,  AlertDialogHeader,  AlertDialogTitle,  AlertDialogTrigger,} from "@/components/ui/alert-dialog"export function DiscardChangesDialog() {  return (    <AlertDialog>      <AlertDialogTrigger>Leave editor</AlertDialogTrigger>      <AlertDialogContent>        <AlertDialogHeader>          <AlertDialogTitle>Discard your changes?</AlertDialogTitle>          <AlertDialogDescription>            Your edits have not been saved. Leave without saving?          </AlertDialogDescription>        </AlertDialogHeader>        <AlertDialogFooter>          <AlertDialogCancel>Stay here</AlertDialogCancel>          <AlertDialogAction>Discard changes</AlertDialogAction>        </AlertDialogFooter>      </AlertDialogContent>    </AlertDialog>  )}

Compact access confirmation

Use the small content size for a short confirmation.

compact-access-confirmation.tsx
import {  AlertDialog,  AlertDialogAction,  AlertDialogCancel,  AlertDialogContent,  AlertDialogDescription,  AlertDialogFooter,  AlertDialogHeader,  AlertDialogTitle,  AlertDialogTrigger,} from "@/components/ui/alert-dialog"export function RevokeAccessDialog() {  return (    <AlertDialog>      <AlertDialogTrigger>Revoke access</AlertDialogTrigger>      <AlertDialogContent size="sm">        <AlertDialogHeader>          <AlertDialogTitle>Revoke access?</AlertDialogTitle>          <AlertDialogDescription>            This person will no longer be able to access the workspace.          </AlertDialogDescription>        </AlertDialogHeader>        <AlertDialogFooter>          <AlertDialogCancel>Cancel</AlertDialogCancel>          <AlertDialogAction>Revoke access</AlertDialogAction>        </AlertDialogFooter>      </AlertDialogContent>    </AlertDialog>  )}

API reference

PropTypeDefaultDescription
AlertDialogAlertDialogPrimitive.Root.Props—Props are forwarded to Base UI AlertDialog.Root.
AlertDialogTriggerAlertDialogPrimitive.Trigger.Props—Props are forwarded to Base UI AlertDialog.Trigger.
AlertDialogPortalAlertDialogPrimitive.Portal.Props—Props are forwarded to Base UI AlertDialog.Portal.
AlertDialogOverlayAlertDialogPrimitive.Backdrop.Props—Props are forwarded to Base UI AlertDialog.Backdrop. The wrapper combines the supplied className with its overlay styles.
AlertDialogContentAlertDialogPrimitive.Popup.Props & { size?: "default" | "sm" }size: "default"Popup props are forwarded to Base UI AlertDialog.Popup. The additional size prop selects the default or small layout; className is combined with the component styles. Content renders inside AlertDialogPortal with an AlertDialogOverlay.
AlertDialogHeaderReact.ComponentProps<"div">—Accepts div props and renders the styled header container.
AlertDialogFooterReact.ComponentProps<"div">—Accepts div props and renders the styled footer container.
AlertDialogMediaReact.ComponentProps<"div">—Accepts div props and renders the styled media container.
AlertDialogTitleReact.ComponentProps<typeof AlertDialogPrimitive.Title>—Accepts Base UI title props and renders the styled dialog title.
AlertDialogDescriptionReact.ComponentProps<typeof AlertDialogPrimitive.Description>—Accepts Base UI description props and renders the styled dialog description.
AlertDialogActionReact.ComponentProps<typeof Button>—Accepts the installed Button component's props and renders that button with alert-dialog action styling. It is a Button wrapper, not a dialog close primitive.
AlertDialogCancelAlertDialogPrimitive.Close.Props & Pick<React.ComponentProps<typeof Button>, "variant" | "size">variant: "outline"; size: "default"Accepts Base UI Close props and the Button variant and size props. Renders the close primitive using Button.

Accessibility

  • Include AlertDialogTitle and a concise AlertDialogDescription so the dialog has a meaningful accessible name and supporting context.
  • Use AlertDialogTrigger as the opener so the primitive can provide its trigger behavior and dialog relationship.
  • Use AlertDialogCancel for the cancel/close control; AlertDialogAction is only a Button wrapper and does not itself close the dialog.
  • Keep action labels specific to the outcome, such as “Delete project,” rather than relying on color or position to communicate intent.
