A modal task with several fields, such as a plan cancellation survey: use the Dialog blocks

Agent notes

On the base twin AlertDialogAction is a plain Button that leaves the dialog open; the radix one closes it on click
AlertDialogTrigger takes its button through render on the base twin and asChild on the radix twin
size sm on AlertDialogContent sets the footer as 2 equal columns, so keep it to 2 buttons

Shadcn Alert Dialog: Confirm Destructive Actions

Shadcn Alert Dialog is a modal primitive for irreversible actions: account deletion, permanent data removal, and destructive confirmations. It follows Radix UI accessibility conventions and Base UI-style composition, with full compatibility for Shadcn Create style tokens so your radius, colors, and typography stay consistent.

It overlays the page with a focused dialog that blocks interaction until the user confirms or cancels a critical action, often using a checkbox or text input to prevent accidental destructive operations.

ReUI lists alert-dialog components inside realistic dashboards and forms so you evaluate focus management, button hierarchy, and confirmation strategies next to tables or other workflows, not in isolation. The sections below explain what the component is, why teams use it, which features matter, and how it integrates with other primitives.

What is Shadcn Alert Dialog?

An alert dialog is a focused modal that blocks interaction with the rest of the page and asks users to confirm a critical, usually irreversible action. Shadcn Alert Dialog follows Radix UI focus trap and keyboard behavior so assistive technologies and keyboard users can dismiss or confirm without mouse.

Components here show delete confirmations with icons, checkbox-gated destructive buttons, text input verification (like 'type DELETE to confirm'), and pairing with primary/secondary button variants so users see intent without confusion.

Why Use Shadcn Alert Dialog?

Teams use alert dialogs when an action is permanent and accidental activation would harm the product or user data. Bulk deletes, account closures, and irreversible state changes need explicit, focused confirmation that a toast or inline message cannot provide.

The layouts on this page show how to combine text, icons, and button variants to make consequences unmistakable without alarm fatigue.

Shadcn Alert Dialog Features

Focus Management. Focus trap ensures users cannot tab away from the dialog until confirmed or cancelled, keeping attention on the decision.
Keyboard Navigation. Escape to cancel, Enter or Tab to move between buttons, and destructive button styling follow WAI-ARIA alert dialog semantics.
Destructive Button Variant. Pair red/warning button styling with Shadcn Button to signal consequence; secondary button for the safe choice (cancel).
Checkbox and Text Gating. Prevent one-click accidents by requiring users to check a Shadcn Checkbox or type confirmation text before delete becomes enabled.
Icon and Copy Alignment. Lucide icons (Trash2, AlertTriangle) paired with clear titles ('Delete Account?') and description make consequence obvious without needing to read a full modal.

Pair alert-dialog with a Shadcn Button to trigger it; use the destructive variant for delete and a secondary variant for cancel. Include a Shadcn Badge in the title if the action affects multiple items ('Delete 5 files?').

Use Shadcn Checkbox or Shadcn Input inside the dialog body to gate the destructive button, preventing accidental clicks. Add a Shadcn Popover for quick help text if users question why a confirmation is needed.

When the action succeeds or fails, show a Shadcn Alert on the page confirming the result. Combine alert-dialog with Sonner for async operations that take time so users can close the dialog before the operation completes.

Frequently Asked Questions

When should I use alert-dialog instead of a regular dialog?

Use alert-dialog only for truly irreversible or high-consequence actions: account deletion, data destruction, irreversible state changes. Use a regular Shadcn Dialog for reversible tasks like editing a name or uploading a file.

Should I add a checkbox or text verification to my delete dialog?

Add friction (checkbox, text input) when the cost of error is high and users repeat the action infrequently. For daily actions like bulk deletes in a data tool, a one-step confirm may be better; for account closure, require confirmation.

What button variant works best for the destructive action?

Use the destructive variant (red background) from Shadcn Button, paired with a secondary or outline variant for cancel so the safe choice stands out equally.

How do I handle alert-dialog focus in Next.js?

Alert-dialog manages its own focus trap via Radix UI primitives. When mounted via state in a client component, focus automatically moves to the first button and returns to the trigger after dismissal.

Can I use alert-dialog on mobile?

Yes. Ensure button hit targets are 44px+, text is readable, and the modal does not exceed viewport height when scrolling. Test focus and dismissal on touch devices.

Is alert-dialog keyboard accessible?

Yes, it follows WAI-ARIA guidance: Escape closes it, Tab cycles buttons, Enter confirms. Test with a screen reader to confirm role and description are announced.

How are ReUI alert-dialog components different from a basic storybook demo?

They show dialogs inside realistic dashboards, forms, and workflows so you can evaluate spacing, button order, and how the overlay interacts with surrounding UI before shipping.
