This section briefly explains how to create a simple DropDownList component and configure its available functionalities in React.
To get start quickly with React DropDownList, you can check on this video:
Dependencies
The following list of dependencies are required to use the DropDownList
component in your application.
|-- @syncfusion/ej2-react-dropdowns
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-data
|-- @syncfusion/ej2-react-base
|-- @syncfusion/ej2-dropdowns
|-- @syncfusion/ej2-lists
|-- @syncfusion/ej2-inputs
|-- @syncfusion/ej2-navigations
|-- @syncfusion/ej2-popups
|-- @syncfusion/ej2-buttons
Installation and configuration
You can use Create-react-app
to setup the applications. To install create-react-app
run the following command.
npm install -g create-react-app
Start a new project using create-react-app command as follows
create-react-app quickstart --scripts-version=react-scripts-ts
cd quickstart
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 DropDownList component, use the following command
npm install @syncfusion/ej2-react-dropdowns –save
Adding DropDownList component
Now, you can start adding DropDownList component in the application. For getting started, add the DropDownList component in src/App.tsx
file using following code.
Add the below code in the src/App.tsx
to initialize the DropDownList.
[Class-component]
import { DropDownListComponent } 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 DropDownList component
<DropDownListComponent id='ddlelement'/>
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { DropDownListComponent } 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 DropDownList component
<DropDownListComponent id='ddlelement'/>
);
}
ReactDOM.render(<App />, document.getElementById('sample'));
Adding CSS reference
Import the DropDownList component required CSS references as follows in src/App.css
.
/* import the DropDownList dependency styles */
@import "../node_modules/@syncfusion/ej2-base/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 DropDownList with data using the dataSource property. Here, an array of string values is passed to the DropDownList component.
[Class-component]
import { DropDownListComponent } 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 DropDownList component
<DropDownListComponent id="ddlelement" dataSource={this.sportsData} />
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { DropDownListComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
const sportsData: string[] = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
return (
// specifies the tag for render the DropDownList component
<DropDownListComponent id="ddlelement" dataSource={sportsData} />
);
}
ReactDOM.render(<App />, document.getElementById('sample'));
Run the application
After completing the configuration required to render a basic DropDownList, run the following command to display the output in your default browser.
npm start
[Class-component]
import { DropDownListComponent } 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 DropDownList component
<DropDownListComponent id="ddlelement" dataSource={this.sportsData} placeholder="Select a game"/>);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { DropDownListComponent } 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 DropDownList component
<DropDownListComponent id="ddlelement" dataSource={this.sportsData} placeholder="Select a game" />
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { DropDownListComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
const sportsData = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
return (
// specifies the tag for render the DropDownList component
<DropDownListComponent id="ddlelement" dataSource={sportsData} placeholder="Select a game"/>);
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { DropDownListComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App(){
// define the array of data
const sportsData: string[] = ['Badminton', 'Cricket', 'Football', 'Golf', 'Tennis'];
return (
// specifies the tag for render the DropDownList component
<DropDownListComponent id="ddlelement" dataSource={sportsData} placeholder="Select 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 DropDownList input element’s width, and the height of the popup list has ‘300px’.
The height and width of the popup list can also be customized using the popupHeight and popupWidth properties respectively.
In the following sample, popup list’s width and height are configured.
[Class-component]
import { DropDownListComponent } 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', 'Hockey', 'Rugby', 'Snooker', 'Tennis'];
render() {
return (
// specifies the tag for render the DropDownList component
<DropDownListComponent id="ddlelement" dataSource={this.sportsData} popupHeight="200px" popupWidth="250px" placeholder="select a game"/>);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { DropDownListComponent } 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', 'Hockey', 'Rugby','Snooker', 'Tennis'];
public render() {
return (
// specifies the tag for render the DropDownList component
<DropDownListComponent id="ddlelement" dataSource={this.sportsData} popupHeight="200px" popupWidth="250px" placeholder="select a game" />
);
}
}
ReactDOM.render(<App />, document.getElementById('sample'));
[Functional-component]
import { DropDownListComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
const sportsData = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Hockey', 'Rugby', 'Snooker', 'Tennis'];
return (
// specifies the tag for render the DropDownList component
<DropDownListComponent id="ddlelement" dataSource={sportsData} popupHeight="200px" popupWidth="250px" placeholder="select a game"/>);
}
ReactDOM.render(<App />, document.getElementById('sample'));
import { DropDownListComponent } from '@syncfusion/ej2-react-dropdowns';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
function App() {
// define the array of data
const sportsData: string[] = ['Badminton', 'Basketball', 'Cricket', 'Football', 'Golf', 'Hockey', 'Rugby','Snooker', 'Tennis'];
return (
// specifies the tag for render the DropDownList component
<DropDownListComponent id="ddlelement" dataSource={sportsData} popupHeight="200px" popupWidth="250px" placeholder="select a game" />
);
}
ReactDOM.render(<App />, document.getElementById('sample'));
