focus-trap-react Build Status

A React component that traps focus.

This component is a light wrapper around focus-trap, tailored to your React-specific needs.

You might want it for, say, building an accessible modal?

Looking for co-maintainers! If you'd like to help maintain this project, please let me know.

What it does

Check out the demo.

Please read the focus-trap documentation to understand what a focus trap is, what happens when a focus trap is activated, and what happens when one is deactivated.

This module simply provides a React component that creates and manages a focus trap.

  • The focus trap automatically activates when mounted (by default, though this can be changed).
  • The focus trap automatically deactivates when unmounted.
  • The focus trap can be activated and deactivated, paused and unpaused via props.


npm install focus-trap-react

dist/focus-trap-react.js is the Babel-compiled file that you'll use.

React dependency

Version 2+ is compatible with React >0.14+.

Version 1 is compatible with React 0.13.

Browser Support

Basically IE9+.

Why? Because this module's core functionality comes from focus-trap, which uses a couple of IE9+ functions.


You wrap any element that you want to act as a focus trap with the <FocusTrap> component. <FocusTrap> expects exactly one child element which can be any HTML element or other React component that contains focusable elements.

For example:

  <div id="modal-dialog" className="modal" >
  <ModalDialog okButtonText="Ok" cancelButtonText="Cancel" />

You can read further code examples in demo/ (it's very simple), and see how it works.

Here's one more simple example:

const React = require('react');
const ReactDOM = require('react-dom');
const FocusTrap = require('../../dist/focus-trap-react');
const container = document.getElementById('demo-one');
class DemoOne extends React.Component {
  constructor(props) {
    this.state = {
      activeTrap: false
    this.mountTrap = this.mountTrap.bind(this);
    this.unmountTrap = this.unmountTrap.bind(this);
  mountTrap() {
    this.setState({ activeTrap: true });
  unmountTrap() {
    this.setState({ activeTrap: false });
  render() {
    const trap = this.state.activeTrap
      ? <FocusTrap
            onDeactivate: this.unmountTrap
          <div className="trap">
              Here is a focus trap
              {' '}
              <a href="#">with</a>
              {' '}
              <a href="#">some</a>
              {' '}
              <a href="#">focusable</a>
              {' '}
              <button onClick={this.unmountTrap}>
                deactivate trap
      : false;
    return (
          <button onClick={this.mountTrap}>
            activate trap
ReactDOM.render(<DemoOne />, container);



Type: Object, optional

Pass any of the options available in focus-trap's createOptions.


Type: Boolean, optional

By default, the FocusTrap activates when it mounts. So you activate and deactivate it via mounting and unmounting. If, however, you want to keep the FocusTrap mounted while still toggling its activation state, you can do that with this prop.

See demo/demo-three.jsx.


Type: Boolean, optional

If you would like to pause or unpause the focus trap (see focus-trap's documentation), toggle this prop.
