## Important Note
|
||
|
|
|
||
|
|
`Tooltip` requires a child node that accepts an `onMouseEnter`, `onMouseLeave`, `onFocus`, `onClick` event. This means the child node must be a built-in component like `div` or `span`, or a custom component that passes its props to its built-in component child.
|
||
|
|
|
||
|
|
## Accessibility
|
||
|
|
|
||
|
|
For accessibility purpose you can use the `id` prop to link your tooltip with another element. For example attaching it to an input element:
|
||
|
|
|
||
|
|
```js
|
||
|
|
<Tooltip
|
||
|
|
...
|
||
|
|
id={this.props.name}>
|
||
|
|
<input type="text"
|
||
|
|
...
|
||
|
|
aria-describedby={this.props.name}/>
|
||
|
|
</Tooltip>
|
||
|
|
```
|
||
|
|
|
||
|
|
If you do it like this, a screenreader would read the content of your tooltip if you focus the input element.
|
||
|
|
|
||
|
|
**NOTE:** `role="tooltip"` is also added to expose the purpose of the tooltip element to a screenreader.
