Use `AlertDialog` for a decision that interrupts the current workflow, such as confirming deletion. It provides an accessible modal with a backdrop and focus management.

## Anatomy

Keep the trigger and popup inside `AlertDialog.Root`. This tree shows the recommended layout for a confirmation dialog.

```text

    │   ├── AlertDialog.Title
    │   └── AlertDialog.Description
    ├── AlertDialog.Body
    └── AlertDialog.Footer
        ├── AlertDialog.Close
        └── Confirmation action
```

| Part                       | Requirement                                   | Purpose                                                                  |
| -------------------------- | --------------------------------------------- | ------------------------------------------------------------------------ |
| `Root`                     | Required                                      | Coordinates open state and modal behavior.                               |
| `Trigger`                  | Optional for a programmatically opened dialog | Opens the dialog and provides a return focus target.                     |
| `Popup`                    | Required                                      | Renders the modal content with focus management.                         |
| `Title`                    | Recommended                                   | Supplies the visible dialog name. An accessible name is always required. |
| `Description`              | Recommended for a confirmation                | Explains the decision and its consequences.                              |
| `Header`, `Body`, `Footer` | Optional layout parts                         | Arrange headings, additional content, and actions.                       |
| `Close`                    | Recommended for cancellation                  | Supplies an explicit close action.                                       |

`Popup` includes the portal, backdrop, and viewport. Put content directly inside it and set `size`, `container`, and focus props on `Popup`. `Header`, `Body`, and `Footer` arrange content; `Title` and `Description` provide the accessible relationships.

The confirmation action is application content, not an exported part. Use `Close` with a synchronous handler or a `Button` with controlled open state for asynchronous confirmation.

## Uncontrolled state

Use `defaultOpen` to set the initial visibility. The dialog owns subsequent changes from its trigger, close controls, and dismissal interactions.

```tsx
import { AlertDialog } from 'twenty-ui/primitives/surfaces';

type DeleteConfirmationProps = { onDelete: () => void };

export const DeleteConfirmation = ({ onDelete }: DeleteConfirmationProps) => (
  <AlertDialog.Root defaultOpen={false}>
    <AlertDialog.Trigger>Delete record</AlertDialog.Trigger>
    <AlertDialog.Popup>
      <AlertDialog.Header>
        <AlertDialog.Title>Delete this record?</AlertDialog.Title>
        <AlertDialog.Description>
          This action cannot be undone.
        </AlertDialog.Description>
      </AlertDialog.Header>
      <AlertDialog.Footer>
        <AlertDialog.Close>Cancel</AlertDialog.Close>
        <AlertDialog.Close onClick={onDelete}>Delete</AlertDialog.Close>
      </AlertDialog.Footer>
    </AlertDialog.Popup>
  </AlertDialog.Root>
);
```

`defaultOpen` defaults to `false`, so it can be omitted. This example uses a synchronous confirmation callback and closes after the action runs.

## Controlled state

Pass `open` and update it with `onOpenChange` to own the same dialog's visibility in React state. The callback receives the next boolean and event details, including changes requested by the trigger and close controls.

```tsx
import { useState } from 'react';
import { AlertDialog } from 'twenty-ui/primitives/surfaces';

type DeleteConfirmationProps = { onDelete: () => void };

export const DeleteConfirmation = ({ onDelete }: DeleteConfirmationProps) => {
  const [open, setOpen] = useState(false);

  return (
    <AlertDialog.Root open={open} onOpenChange={setOpen}>
      <AlertDialog.Trigger>Delete record</AlertDialog.Trigger>
      <AlertDialog.Popup>
        <AlertDialog.Header>
          <AlertDialog.Title>Delete this record?</AlertDialog.Title>
          <AlertDialog.Description>
            This action cannot be undone.
          </AlertDialog.Description>
        </AlertDialog.Header>
        <AlertDialog.Footer>
          <AlertDialog.Close>Cancel</AlertDialog.Close>
          <AlertDialog.Close onClick={onDelete}>Delete</AlertDialog.Close>
        </AlertDialog.Footer>
      </AlertDialog.Popup>
    </AlertDialog.Root>
  );
};
```

For asynchronous confirmation, use a `Button` with your action handler instead of `AlertDialog.Close`. Keep `open` true while the action is pending, call `setOpen(false)` after it succeeds, and show an error inside the dialog if it fails.

## Compose with buttons

Use `render` to give the trigger and close controls Twenty UI button styling. The dialog parts supply their interaction handlers and refs to the buttons.

```tsx
import { Button } from 'twenty-ui/primitives/input';
import { AlertDialog } from 'twenty-ui/primitives/surfaces';

type DeleteConfirmationProps = { onDelete: () => void };

export const DeleteConfirmation = ({ onDelete }: DeleteConfirmationProps) => (
  <AlertDialog.Root>
    <AlertDialog.Trigger
      render={<Button color="danger">Delete record</Button>}
    />
    <AlertDialog.Popup>
      <AlertDialog.Header>
        <AlertDialog.Title>Delete this record?</AlertDialog.Title>
        <AlertDialog.Description>
          This action cannot be undone.
        </AlertDialog.Description>
      </AlertDialog.Header>
      <AlertDialog.Footer>
        <AlertDialog.Close render={<Button variant="outline">Cancel</Button>} />
        <AlertDialog.Close
          onClick={onDelete}
          render={<Button color="danger">Delete</Button>}
        />
      </AlertDialog.Footer>
    </AlertDialog.Popup>
  </AlertDialog.Root>
);
```

Keep each action as a single interactive control. If you wrap `Button` in your own component, [forward the supplied props and ref](/ui/primitives/overview#custom-components).

## Sizing and portals

`Popup.size` defaults to `md`; see the reference for supported sizes. Use `container` to override the theme's portal container and `keepMounted` to retain mounted content when closed.

## Focus and dismissal

The dialog traps focus while open. Escape can dismiss it; clicking the backdrop does not. Always provide a visible Cancel or Close action. Keep the initial focus on the least destructive action, and preserve a meaningful return focus target when the action removes its trigger. Use `Popup.initialFocus` and `Popup.finalFocus` to customize focus behavior.

## Props

The reference is generated from the public component types. Native attributes, including accessible names and event handlers, are also accepted on parts that render elements.
