Keyboard Navigation
A user can use the following keys to interact with the Autocomplete component:
Key | Action |

Alt + ↓ | Opens the drop-down menu. |
Alt + ↑ / Esc | Closes the drop-down menu. |
↑ / ↓ | Moves focus to the previous/next menu item. |
Page Up / Page Down | Moves focus to the first/last menu item. |
Enter | Selects focused menu item. |
Use the registerKeyHandler(key, handler) method to implement a custom handler for a key.
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import { Autocomplete } from 'devextreme-react/autocomplete';
- class App extends React.Component {
- constructor(props) {
- super(props);
- this.autocompleteRef = React.createRef();
- }
- render() {
- return (
- <Autocomplete ref={this.autocompleteRef} />
- );
- }
- get autocomplete() {
- return this.autocompleteRef.current.instance;
- }
- componentDidMount() {
- this.autocomplete.registerKeyHandler('backspace', function(e) {
- // The argument "e" contains information on the event
- });
- this.autocomplete.registerKeyHandler('space', function(e) {
- // ...
- });
- }
- }
- export default App;
Screen Reader Support
The Autocomplete component supports screen readers and complies to WAI-ARIA standards.
To improve accessibility, use the inputAttr property to specify aria-label for the component. You do not need to specify aria-label
if you use label.
