# Tooltip

Tooltips are floating labels that briefly explain the function of a user interface element. They must be specified inside the `overlay` prop of an activator component. Currently, activator components are `Button`, `Link`, and `Pressable`.

The library takes care of applying the WAI-ARIA Tooltip Widget pattern automatically for the activator and the tooltip content. Expect screen readers to read the tooltip content when the user focuses the activator.

```tsx
import {
  render,
  Icon,
  Pressable,
  Tooltip,
} from '@shopify/checkout-ui-extensions-react';

render('Checkout::Dynamic::Render', () => <Extension />);

function Extension() {
  return (
    <Pressable
      overlay={
        <Tooltip>In case we need to contact you about your order</Tooltip>
      }
    >
      <Icon source="questionFill" />
    </Pressable>
  );
}

```

```js
import {
  extend,
  Icon,
  Pressable,
  Tooltip,
} from '@shopify/checkout-ui-extensions';

extend('Checkout::Dynamic::Render', (root) => {
  const tooltipFragment = root.createFragment();
  const tooltip = root.createComponent(
    Tooltip,
    {},
    'In case we need to contact you about your order',
  );
  tooltipFragment.appendChild(tooltip);
  const pressable = root.createComponent(
    Pressable,
    {overlay: tooltipFragment},
    [root.createComponent(Icon, {source: 'questionFill'})],
  );

  root.appendChild(pressable);
});

```
