21 Feb 20264 minutes to read

The AutoComplete has built-in support to highlight the searched characters on suggested list items when the highlight property is enabled.

In the following sample, the matched character in the suggestion list is customized using the e-highlight class.

index.jsx

import { AutoCompleteComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
export default class App extends React.Component {
    // define the JSON of data
    sportsData = [
        { Id: 'Game1', Game: 'Badminton' },
        { Id: 'Game2', Game: 'Basketball' },
        { Id: 'Game3', Game: 'Cricket' },
        { Id: 'Game4', Game: 'Football' },
        { Id: 'Game5', Game: 'Golf' },
        { Id: 'Game6', Game: 'Hockey' },
        { Id: 'Game7', Game: 'Rugby' },
        { Id: 'Game8', Game: 'Snooker' }
    ];
    // maps the appropriate column to fields property
    fields = { value: 'Game' };
    render() {
        return (
        // specifies the tag for render the AutoComplete component
        <AutoCompleteComponent id="atcelement" dataSource={this.sportsData} fields={this.fields} placeholder="Find a game" highlight={true}/>);
    }
}
ReactDOM.render(<App />, document.getElementById('sample'));
