# Callout - React

Callouts are snippets of information, drawing attention to important content.

## React

### Import

You can import the component like so:

```js
import { Attention } from '@warp-ds/react'
```

or import it individually to optimize your JS bundle size by adding only the components you need:

```js
import { Attention } from '@warp-ds/react/components/attention'
```

### Visual options

#### Default (inline type)

```js
<div>
  <Box info>
    <h1 aria-details='callout-bubbletext'>I am a box full of info</h1>
  </Box>
  <Attention callout placement='right' isShowing={true}>
    <p id='callout-bubbletext'>
      I'm a callout (inline type)
    </p>
  </Attention>
</div>
```

#### Highlight with close button (popover type)

```js
function DismissibleHighlight() {
  const [show, setShow] = React.useState(false)
  const targetEl = React.useRef()

  return (
    <div className='flex flex-col justify-between h-[200]'>
      <Button
        small
        aria-expanded={show}
        aria-controls='highlight-example'
        utility
        onClick={() => setShow(!show)}
        className='w-max mb-0'
      >
        Show an onboarding hint
      </Button>
      <div>
        <div ref={targetEl} className="w-2/3" aria-details='highlight-bubble-text'>
          <Box info>
            <h1>I am a box full of info</h1>
          </Box>
        </div>
        <Attention
          highlight
          placement='right'
          isShowing={show}
          canClose
          onDismiss={() => setShow(false)}
          targetEl={targetEl}
          id='highlight-example'
        >
          <p id='highlight-bubble-text'>
            I'm a highlight (popover type) that is dismissable
          </p>
        </Attention>
      </div>
    </div>
  )
}
```

### Flip prop

The attention component uses the Floating-ui library to calculate its position.
By default, the `flip` prop is set to `false`, which means that the attention component will not flip its position to the opposite side.

Try to scroll up and down and see how the attention component doesn't move:

When `flip` is set to `true`, it will instead trigger [Floating-ui's flip() function](https://floating-ui.com/docs/flip) that will make sure that the attention component stays in viewport, by flipping it to the opposite side.

Try to scroll up and down and see how the attention component moves its position to the opposite side to keep itself in viewport as long as possible:

### CrossAxis prop

The `crossAxis` prop decides whether to check for cross axis overflow or not when `flip` is set to `true`.
By default, the `crossAxis` prop is set to `false`, which means that the attention component will ignore cross axis overflow.

### FallbackPlacements prop

By default, `fallbackPlacements` is `undefined`.
If `flip`is set to `true`, then you have the option to also use `fallbackPlacements` prop and pass in an array of preferred placements that you want the attention component to try if there is no longer any space left to position it to the initial `placement`, e.g. `['right', 'top']`.

Try to scroll up and down and see how the attention component's position starts at the `bottom` but then moves to the `right` and then to the `top`:

### Accessibility

The attention component handles accessibility automatically by wrapping its slotted content with a `div` that has a default `role` attribute set to `img` when the `callout` or `highlight` prop is activated, and a default localized `aria-label`.

It is possible to remove the default `role` and override the `aria-label` attribute:

```js
<Attention highlight placement='right' isShowing={true} role='' aria-label=''>
  <p id='highlight-bubbletext'>
    I'm a highlight (popover type) speech bubble with overridden role and aria-label attributes
    pointing up.
  </p>
</Attention>
```

If the user chooses to remove the `role` and/or override the `aria-label` attributes then it is important to also add `aria-details` on the target element.
