Installation and configuration

create-react-app quickstart --scripts-version=react-scripts-ts

cd quickstart

Adding syncfusion packages

To install AutoComplete component, use the following command

npm install @syncfusion/ej2-react-dropdowns --save

Adding AutoComplete component

Now, you can start adding AutoComplete component in the application. For getting started, add the AutoComplete component in src/App.tsx file using following code.

Add the below code in the src/App.tsx to initialize the AutoComplete.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { AutoCompleteComponent } from '@syncfusion/ej2-react-dropdowns';

export default class App extends React.Component<{}, {}> {
  render() {
    return (
       // specifies the tag for render the AutoComplete component
      <AutoCompleteComponent id='atcelement'></AutoCompleteComponent>
    );
  }
}

ReactDOM.render(<App />, document.getElementById('sample'));

Adding CSS reference

Import the AutoComplete component required CSS references as follows in src/App.css.

/* import the AutoComplete dependency styles */

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-react-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-react-dropdowns/styles/material.css";

Binding data source

After initialization, populate the data using dataSource property. Here, an array of string values is passed to the AutoComplete component.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { AutoCompleteComponent } from '@syncfusion/ej2-react-dropdowns';

export default class App extends React.Component<{}, {}> {
  // define the array of data
  private sportsData: string[] = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Gymnastics', 'Hockey', 'Rugby', 'Snooker', 'Tennis'];
  render() {
    return (
        // specifies the tag for render the AutoComplete component
      <AutoCompleteComponent id="atcelement" dataSource={this.sportsData} />
    );
  }
}
ReactDOM.render(<App />, document.getElementById('sample'));

After completing the configuration required to render a basic AutoComplete, run the following command to display the output in your default browser.
