15 Oct 2021 / 4 minutes to read

The following section explains the steps required to build the Splitter component with step-by-step procedure.

Dependencies

The following list of dependencies required to use the Splitter component in your application:

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

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

create-react-app quickstart

cd quickstart

Install the below required dependency package in order to use the Splitter component in your application.

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

The Splitter CSS files are available in the ej2-layouts package folder. This can be referred in your application using the following code.

[src/App.css]

@import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-layouts/styles/material.css';

Adding Splitter to the project

The Splitter can be initialized through <SplitterComponent> tag-directive with <PanesDirective> and <PaneDirective> as child elements respectively.

Please refer the below code snippet,

import { PaneDirective, PanesDirective, SplitterComponent } from '@syncfusion/ej2-react-layouts';
import * as React from "react";

class App extends React.Component {
  public render() {
return (
  <div className="App">
  <SplitterComponent id="splitter" height="250px" width="600px">
      <PanesDirective>
        <PaneDirective/>
        <PaneDirective/>
        <PaneDirective/>
      </PanesDirective>
  </SplitterComponent>
  </div>
);
  }
}

export default App;

After completing the configurations to render the Splitter, use the following command to display the output in your default browser.

npm start

Output will be as follows:

    </SplitterComponent>
  </div>);
    }
}
export default App;

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import App from './App';
ReactDOM.render(<App />, document.getElementById('container'));

Orientation

Splitter supports both Horizontal and Vertical orientation for the panes. By default, it will be rendered in Horizontal orientation. You can change it by using orientation property.
