## Import

Chakra UI exports 7 alert dialog related components.

- `AlertDialog`: provides context and state for the dialog.
- `AlertDialogHeader`: should contain the title announced by screen readers.
- `AlertDialogBody`: should contain the description announced by screen readers.
- `AlertDialogFooter`: should contain the actions of the dialog.
- `AlertDialogOverlay`: The dimmed overlay behind the dialog.
- `AlertDialogContent`: The wrapper for the alert dialog's content.
- `AlertDialogCloseButton`: The button that closes the dialog.

```js
import {
  AlertDialog,
  AlertDialogBody,
  AlertDialogFooter,
  AlertDialogHeader,
  AlertDialogContent,
  AlertDialogOverlay,
  AlertDialogCloseButton,
} from '@chakra-ui/react'
```

## Usage

`AlertDialog` requires that you provide the `leastDestructiveRef` prop.

Based on
[WAI-ARIA specifications](https://www.w3.org/TR/wai-aria-practices/#alertdialog),
focus should be placed on the least destructive element when the dialog opens,
to prevent users from accidentally confirming the destructive action.

```jsx
function AlertDialogExample() {
  const { isOpen, onOpen, onClose } = useDisclosure()
  const cancelRef = React.useRef()

  return (
    <>
      <Button colorScheme='red' onClick={onOpen}>
        Delete Customer
      </Button>

      <AlertDialog
        isOpen={isOpen}
        leastDestructiveRef={cancelRef}
        onClose={onClose}
      >
        <AlertDialogOverlay>
          <AlertDialogContent>
            <AlertDialogHeader fontSize='lg' fontWeight='bold'>
              Delete Customer
            </AlertDialogHeader>

            <AlertDialogBody>
              Are you sure? You can't undo this action afterwards.
            </AlertDialogBody>

            <AlertDialogFooter>
              <Button ref={cancelRef} onClick={onClose}>
                Cancel
              </Button>
              <Button colorScheme='red' onClick={onClose} ml={3}>
                Delete
              </Button>
            </AlertDialogFooter>
          </AlertDialogContent>
        </AlertDialogOverlay>
      </AlertDialog>
    </>
  )
}
```

### Changing the transition

The `Modal` comes with a scale transition by default but you can change it by
passing a `motionPreset` prop, and set its value to either `slideInBottom`,
`slideInRight`, or `scale`.

```jsx
function TransitionExample() {
  const { isOpen, onOpen, onClose } = useDisclosure()
  const cancelRef = React.useRef()

  return (
    <>
      <Button onClick={onOpen}>Discard</Button>
      <AlertDialog
        motionPreset='slideInBottom'
        leastDestructiveRef={cancelRef}
        onClose={onClose}
        isOpen={isOpen}
        isCentered
      >
        <AlertDialogOverlay />

        <AlertDialogContent>
          <AlertDialogHeader>Discard Changes?</AlertDialogHeader>
          <AlertDialogCloseButton />
          <AlertDialogBody>
            Are you sure you want to discard all of your notes? 44 words will be
            deleted.
          </AlertDialogBody>
          <AlertDialogFooter>
            <Button ref={cancelRef} onClick={onClose}>
              No
            </Button>
            <Button colorScheme='red' ml={3}>
              Yes
            </Button>
          </AlertDialogFooter>
        </AlertDialogContent>
      </AlertDialog>
    </>
  )
}
```

## Accessibility

- `AlertDialog` has role `alertdialog`, and `aria-modal` set to true.
- When the dialog opens, focus is automatically set to the least destructive
  element.
- When the dialog opens, the content in the `AlertDialogHeader` and
  `AlertDialogBody` are announced by screen readers via `aria-labelledby` and
  `aria-describedby` attributes.
- Clicking on the overlay closes the `AlertDialog`.
- Pressing <kbd>esc</kbd> closes the dialog.
