FocusScope

{docs.exports.FocusScope.description}

Introduction

FocusScope is a utility component that can be used to manage focus for its descendants. When the contain prop is set, focus is contained within the scope. This is useful when implementing overlays like modal dialogs, which should not allow focus to escape them while open. In addition, the restoreFocus prop can be used to restore focus back to the previously focused element when the focus scope unmounts, for example, back to a button which opened a dialog. A FocusScope can also optionally auto focus the first focusable element within it on mount when the autoFocus prop is set.

The hook can also be used in combination with a FocusScope to programmatically move focus within the scope. For example, arrow key navigation could be implemented by handling keyboard events and using a focus manager to move focus to the next and previous elements.

Props

FocusManager Interface

To get a focus manager, call the hook from a component within the FocusScope. A focus manager supports the following methods:

Example

A basic example of a focus scope that contains focus within it is below. Clicking the "Open" button mounts a FocusScope, which auto focuses the first input inside it. Once open, you can press the Tab key to move within the scope, but focus is contained inside. Clicking the "Close" button unmounts the focus scope, which restores focus back to the button.

'use client';
import React from 'react';
import {FocusScope} from '@react-aria/focus';

function Example() {
  let [isOpen, setOpen] = React.useState(false);
  return (
    <>
      <button onClick={() => setOpen(true)}>Open</button>
      {isOpen &&
        <FocusScope contain restoreFocus autoFocus>
          <label htmlFor="first-input">First Input</label>
          <input id="first-input" />
          <label htmlFor="second-input">Second Input</label>
          <input id="second-input" />
          <button onClick={() => setOpen(false)}>Close</button>
        </FocusScope>
      }
    </>
  );
}

useFocusManager Example

This example shows how to use useFocusManager to programmatically move focus within a FocusScope. It implements a basic toolbar component, which allows using the left and right arrow keys to move focus to the previous and next buttons. The wrap option is used to make focus wrap around when it reaches the first or last button.

'use client';
import {FocusScope} from '@react-aria/focus';
import {useFocusManager} from '@react-aria/focus';

function Toolbar(props) {
  return (
    <div role="toolbar">
      <FocusScope>
        {props.children}
      </FocusScope>
    </div>
  );
}

function ToolbarButton(props) {
  let focusManager = useFocusManager();
  let onKeyDown = (e) => {
    switch (e.key) {
      case 'ArrowRight':
        focusManager.focusNext({wrap: true});
        break;
      case 'ArrowLeft':
        focusManager.focusPrevious({wrap: true});
        break;
    }
  };

  return (
    <button
      onKeyDown={onKeyDown}>
      {props.children}
    </button>
  );
}

<Toolbar>
  <ToolbarButton>Cut</ToolbarButton>
  <ToolbarButton>Copy</ToolbarButton>
  <ToolbarButton>Paste</ToolbarButton>
</Toolbar>
