Dependencies

The following list of dependencies are required to use the DropDownButton component in your application.

|-- @syncfusion/ej2-react-splitbuttons
    |-- @syncfusion/ej2-react-base
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-splitbuttons
        |-- @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

To set-up a React application in TypeScript environment, run the following command.

npx create-react-app my-app --template typescript

cd my-app

npm start

To set-up a React application in JavaScript environment, run the following command.

npx create-react-app my-app

cd my-app

npm start

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 DropDownButton component, use the following command

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

Adding CSS reference

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

/* import the DropDownButton 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-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";

Adding DropDownButton component

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

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

import { enableRipple } from '@syncfusion/ej2-base';
import { DropDownButtonComponent } from '@syncfusion/ej2-react-splitbuttons';
import * as React from 'react';
import './App.css';

enableRipple(true);

// To render DropDownButton.
function App() {
  return (
    <div style=>
      <DropDownButtonComponent id="element" />
    </div>
  );
}
export default App;

Binding data source

After initialization, populate the DropDownButton with data using the items property. Here, an array of string values is passed to the DropDownButton component.

import { enableRipple } from '@syncfusion/ej2-base';
import { DropDownButtonComponent, ItemModel } from '@syncfusion/ej2-react-splitbuttons';
import * as React from 'react';
import './App.css';

enableRipple(true);

// To render DropDownButton.
function App() {
  let items: ItemModel[] = [
    {
      text: 'Cut',
    },
    {
      text: 'Copy',
    },
    {
      text: 'Paste',
    }];
    return (
      <div style=>
        <DropDownButtonComponent id="element" items={items}> Clipboard </DropDownButtonComponent>
      </div>
    );
}
export default App;

Run the application

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

   npm start

The following example shows a basic Drop Button component.

app.jsx
app.tsx
import { enableRipple } from '@syncfusion/ej2-base';
import { DropDownButtonComponent } from '@syncfusion/ej2-react-splitbuttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';
enableRipple(true);
// To render DropDownButton.
function App() {
    let items = [
        {
            text: 'Cut',
        },
        {
            text: 'Copy',
        },
        {
            text: 'Paste',
        }
    ];
    return (<div>
       <DropDownButtonComponent id="element" items={items}> Clipboard </DropDownButtonComponent>
      </div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('button'));
import { enableRipple } from '@syncfusion/ej2-base';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import { DropDownButtonComponent, ItemModel } from '@syncfusion/ej2-react-splitbuttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';
enableRipple(true);

// To render DropDownButton.
function App() {
  let items: ItemModel[] = [
        {
            text: 'Cut',
        },
        {
            text: 'Copy',
        },
        {
            text: 'Paste',
        }];
    return (
      <div>
       <DropDownButtonComponent id="element" items = {items}> Clipboard </DropDownButtonComponent>
      </div>
    );
}
export default App;
ReactDom.render(<App />,document.getElementById('button'));
