11 Jan 2022 / 3 minutes to read

This section explains how to create a simple ContextMenu, and configure its available functionalities in React

Dependencies

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

|-- @syncfusion/ej2-react-navigations
    |-- @syncfusion/ej2-react-base
    |-- @syncfusion/ej2-navigations
        |-- @syncfusion/ej2-base
        |-- @syncfusion/ej2-data
        |-- @syncfusion/ej2-inputs
        |-- @syncfusion/ej2-lists
        |-- @syncfusion/ej2-popups
            |-- @syncfusion/ej2-buttons

Setup your development environment

You can use Create-react-app to setup the applications. To install create-react-app run the following command.

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

‘react-scripts-ts’ is used for creating React app with typescript.

Adding Syncfusion packages

All the available Essential JS 2 packages are published in npmjs.com public registry.

To install ContextMenu component, use the following command

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

The above command installs ContextMenu dependencies which are required to render the component in the React environment.

Adding Style sheet to the Application

Add ContextMenu component’s styles as given below in App.css.

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-lists/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-navigations/styles/material.css";

/* Context Menu target */

#target {
    border: 1px dashed;
    height: 150px;
    padding: 10px;
    position: relative;
    text-align: justify;
    color: gray;
    user-select: none;
}

Add ContextMenu to the project

Now, you can add ContextMenu component in the application For getting started, add ContextMenu component in src/App.tsx file and the options contain menuItems and target in which ContextMenu will be opened. Using the following code snippet.

import { ContextMenuComponent, MenuItemModel } from '@syncfusion/ej2-react-navigations';
import * as React from 'react';
import './App.css';

class App extends React.Component<{}, {}> {
  private menuItems: MenuItemModel[] = [
    {
        text: 'Cut'
    },
    {
        text: 'Copy'
    },
    {
        text: 'Paste'
    }];

  public render() {
    return (
      // specifies the tag to render the ContextMenu component
      <div>
        <div id="target">Right click / Touch hold to open the ContextMenu</div>
        <ContextMenuComponent target="#target" items={this.menuItems} />
      </div>
    );
  }
}

import { ContextMenuComponent } from '@syncfusion/ej2-react-navigations';
import * as React from 'react';
import './App.css';
class App extends React.Component {
    constructor() {
        super(...arguments);
        this.menuItems = [
            {
                text: 'Cut'
            },
            {
                text: 'Copy'
            },
            {
                text: 'Paste'
            }
        ];
    }
    render() {
        return (
        // specifies the tag to render the ContextMenu component
        <div>
        <div id="target">Right click / Touch hold to open the ContextMenu</div>
        <ContextMenuComponent target="#target" items={this.menuItems}/>
      </div>);
    }
}

Run the application

Run the application in the browser using the following command:

npm start

The following example shows a basic ContextMenu component.
