Autofill in React AutoComplete component

21 Feb 20264 minutes to read

The React AutoComplete supports autofill behavior with the help of the autofill property. Whenever you change the input value and press the down arrow key, the AutoComplete will autocomplete your data by matching the typed character. If no matches are found, the AutoComplete does not suggest any item.

In the following sample, the autofill feature is demonstrated with the AutoComplete.

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" autofill={true}/>);
    }
}
ReactDOM.render(<App />, document.getElementById('sample'));

index.tsx

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
    private sportsData: { [key: string]: Object }[] = [
       { 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
    private fields: object = { value: 'Game' };

    public render() {
        return (
             // specifies the tag for render the AutoComplete component
            <AutoCompleteComponent id="atcelement" dataSource={this.sportsData} fields={this.fields} placeholder="Find a game" autofill={true} />
        );
    }
}
ReactDOM.render(<App />, document.getElementById('sample'));
