This section explains how to create a simple MultiSelect component and configure its available functionalities in React.
To get start quickly with React MultiSelect component, you can check on this video:
Dependencies
The following list of dependencies are required to use the MultiSelect
component in your application.
|-- @syncfusion/ej2-react-dropdowns
|-- @syncfusion/ej2-react-base
|-- @syncfusion/ej2-dropdowns
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-data
|-- @syncfusion/ej2-lists
|-- @syncfusion/ej2-inputs
|-- @syncfusion/ej2-navigations
|-- @syncfusion/ej2-popups
|-- @syncfusion/ej2-buttons
Installation and configuration
To easily set up a React application, use create-vite-app
, which provides a faster development environment, smaller bundle sizes, and optimized builds compared to traditional tools like create-react-app
. For detailed steps, refer to the Vite installation instructions. Vite sets up your environment using JavaScript and optimizes your application for production.
Note: To create a React application using
create-react-app
, refer to this documentation for more details.
To create a new React application, run the following command.
npm create vite@latest my-app
To set-up a React application in TypeScript environment, run the following command.
npm create vite@latest my-app -- --template react-ts
cd my-app
npm run dev
To set-up a React application in JavaScript environment, run the following command.
npm create vite@latest my-app -- --template react
cd my-app
npm run dev
Adding syncfusion® packages
All the available Essential® JS 2 packages are published in npmjs.com
public registry. You can choose the component that you want to install.
To install MultiSelect component, use the following command
npm install @syncfusion/ej2-react-dropdowns --save
Adding MultiSelect component
Now, you can start adding MultiSelect component in the application. For getting started, add the MultiSelect component in src/App.tsx
file using following code.
Add the below code in the src/App.tsx
to initialize the MultiSelect.
[Class-component]
import { MultiSelectComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from "react-dom";
export default class App extends React.Component<{}, {}> {
public render() {
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id='mtselement'/>
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { MultiSelectComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from "react-dom";
function App(){
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id='mtselement'/>
);
}
ReactDOM.render(<App />, document.getElementById('sample'));
Adding CSS reference
Import the MultiSelect component required CSS references as follows in src/App.css
.
/* import the MultiSelect dependency styles */
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-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 MultiSelect component.
[Class-component]
import { MultiSelectComponent } 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 array of data
private sportsData: string[] = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Gymnastics', 'Hockey', 'Rugby', 'Snooker', 'Tennis'];
public render() {
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={this.sportsData} />
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { MultiSelectComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App(){
// define the array of data
let sportsData: string[] = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Gymnastics', 'Hockey', 'Rugby', 'Snooker', 'Tennis'];
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={sportsData} />
);
}
ReactDOM.render(<App />, document.getElementById('sample'));
Run the application
Now run the npm run dev
command in the console to start the development server. This command compiles your code and serves the application locally, opening it in the browser.
npm run dev
[Class-component]
import { MultiSelectComponent } 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 array of data
sportsData = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
render() {
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={this.sportsData} placeholder="Find a game"/>);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { MultiSelectComponent } 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 array of data
private sportsData: string[] = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
public render() {
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={this.sportsData} placeholder="Find a game" />
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { MultiSelectComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
let sportsData = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={sportsData} placeholder="Find a game"/>);
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { MultiSelectComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
let sportsData: string[] = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={sportsData} placeholder="Find a game" />
);
}
ReactDOM.render(<App />, document.getElementById('sample'));
Configure the Popup List
By default, the width of the popup list automatically adjusts according to the MultiSelect input element’s width and the height of the popup list has ‘300px’.
You can also customize the suggestion list height and width using popupHeight and popupWidth properties respectively.
In the following sample, popup list’s width and height are configured.
[Class-component]
import { MultiSelectComponent } 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 array of data
sportsData = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Gymnastics', 'Hockey', 'Rugby', 'Snooker', 'Tennis'];
render() {
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={this.sportsData} popupHeight="250px" popupWidth="250px" placeholder="Find a game"/>);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { MultiSelectComponent } 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 array of data
private sportsData: string[] = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Gymnastics', 'Hockey', 'Rugby','Snooker', 'Tennis'];
public render() {
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={this.sportsData} popupHeight="250px" popupWidth="250px" placeholder="Find a game" />
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { MultiSelectComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
let sportsData = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Gymnastics', 'Hockey', 'Rugby', 'Snooker', 'Tennis'];
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={sportsData} popupHeight="250px" popupWidth="250px" placeholder="Find a game"/>);
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { MultiSelectComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
let sportsData: string[] = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Gymnastics', 'Hockey', 'Rugby','Snooker', 'Tennis'];
return (
// specifies the tag for render the MultiSelect component
<MultiSelectComponent id="mtselement" dataSource={sportsData} popupHeight="250px" popupWidth="250px" placeholder="Find a game" />
);
}
ReactDOM.render(<App />, document.getElementById('sample'));
