It is as simple as wrapping your component with the FocusTrap and rest will be be taken care of.
Using npm:
$ npm i react-trap-focus
Using yarn:
$ yarn add react-trap-focus
There are 2 ways in which you can use it.
The default query selector is
[role="button"]
but you can pass whatever your application sees fit.
import { FocusTrap } from 'react-trap-focus'
<FocusTrap>
<Modal.Body>
// Do Something
</Modal.Body>
</FocusTrap>
import { FocusTrap } from 'react-trap-focus'
<FocusTrap querySelector={'div.highlighted > p'}>
// Do something / wrap any component
</FocusTrap>
The package also exposes focusTrap = (event: KeyboardEvent, elements: HTMLElement[])
function which can be used directly on keyboard events.
Pass the event and the elements list you want to be focus trapped.
import { focusTrap } from 'react-trap-focus'
const allButtonEls = document.querySelectorAll('[role="button"]')
const onKeyDown = event => focusTrap(event, allButtonEls)
return (
<div onKeyDown={onKeyDown}>
// Do something
</div>
)
