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.Root
├── AlertDialog.Trigger
└── AlertDialog.Popup
├── AlertDialog.Header
│ ├── 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) => (
Delete record
Delete this record?
This action cannot be undone.
Cancel
Delete
);
```
`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 (
Delete record
Delete this record?
This action cannot be undone.
Cancel
Delete
);
};
```
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) => (
Delete record}
/>
Delete this record?
This action cannot be undone.
Cancel} />
Delete}
/>
);
```
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.
