Dismiss Behavior
Dismiss Behavior
Alert dialogs require explicit user action by design—users must click an action button to close the dialog. By default, backdrop clicks and ESC key are both disabled to prevent accidental dismissal of critical confirmations.
Default (Requires Action)
With default settings, users cannot close the dialog by clicking outside or pressing ESC. They must choose an action button.
Allow Backdrop Clicks
Set isDismissable=true to let users click outside the dialog to close it. Useful for less critical confirmations.
Full Flexibility
Enable both isDismissable=true and isKeyboardDismissDisabled=false for maximum flexibility. Users can close via backdrop, Esc, or button.

function CustomAlertDialog() {
return (
<AlertDialog>
<Button variant="danger">Delete</Button>
<AlertDialog.Container backdropClassName="bg-red-950/90" className="items-start pt-20">
<AlertDialog.Dialog className="border-2 border-red-500 sm:max-w-[400px]">
{({close}) => (
<>
<AlertDialog.Header>
<AlertDialog.Icon status="danger" />
<AlertDialog.Heading>Custom Styled Alert</AlertDialog.Heading>
</AlertDialog.Header>
<AlertDialog.Body>
<p>This alert dialog has custom styling applied via Tailwind classes</p>
</AlertDialog.Body>
<AlertDialog.Footer>
<Button variant="tertiary" onPress={close}>
Cancel
</Button>
<Button variant="danger" onPress={close}>
Delete
</Button>

)}
</AlertDialog.Dialog>
</AlertDialog.Container>
</AlertDialog>
);
}Customizing the component classes
To customize the AlertDialog component classes, you can use the @layer components directive.
@layer components {
.alert-dialog__backdrop {
@apply bg-gradient-to-br from-black/60 to-black/80;
}
.alert-dialog__dialog {
@apply rounded-2xl border border-red-500/20 shadow-2xl;
}
.alert-dialog__header {
@apply gap-4;
}
.alert-dialog__icon {
@apply size-16;
}
.alert-dialog__close-trigger {
@apply rounded-full bg-white/10 hover:bg-white/20;
}
}HeroUI follows the BEM methodology to ensure component variants and states are reusable and easy to customize.

useOverlayState Hook
import {useOverlayState} from "@heroui/react";
const state = useOverlayState({
defaultOpen: false,
onOpenChange: (isOpen) => console.log(isOpen),
});
state.isOpen; // Current state
state.open(); // Open dialog
state.close(); // Close dialog
state.toggle(); // Toggle state
state.setOpen(); // Set state directlyAccessibility
Implements WAI-ARIA AlertDialog pattern:
- Focus trap: Focus locked within alert dialog
- Keyboard:
ESCcloses (when enabled),Tabcycles elements - Screen readers: Proper ARIA attributes with
role="alertdialog" - Scroll lock: Body scroll disabled when open
- Required action: Defaults to requiring explicit user action (no backdrop/ESC dismiss)
