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

|-- @syncfusion/ej2-vue-navigations
    |-- @syncfusion/ej2-vue-base
    |-- @syncfusion/ej2-navigations

Installation and configuration

You can use Vue CLI to setup your vue applications. To install Vue CLI use the following command.

npm install -g @vue/cli

npm install -g @vue/cli-init

Start a new project using below Vue CLI command.

vue init webpack-simple quickstart

cd quickstart

npm install

Install Syncfusion ContextMenu packages using below command.

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

Registering ContextMenu component using `Vue.use()`

Import the ContextMenu Plugin from the Essential JS 2 Vue package and register the same using Vue.use() with Component Plugin as its argument.

Refer to the code snippet given below.

import Vue from 'vue';
import { ContextMenuPlugin } from "@syncfusion/ej2-vue-navigations";

Vue.use(ContextMenuPlugin);

export default {}

By registering component plugin in Vue, all child directives are also globally registered. We can also use Vue.Component() to register ContextMenu. Refer here to know more about component registration.

Initialize ContextMenu

Add the EJ2 Vue ContextMenu using <ejs-contextmenu> to the <template> section of the App.vue file in src directory.

<template>
<div>
<div id="target">Right click / Touch hold to open the ContextMenu</div>
<ejs-contextmenu target='#target' :items='menuItems'></ejs-contextmenu>
</div>
</template>

<script>
import Vue from 'vue';
import { ContextMenuPlugin } from "@syncfusion/ej2-vue-navigations";

Vue.use(ContextMenuPlugin);

export default {
    data () {
        return {
            menuItems:[
            {
                text: 'Cut'
            },
            {
                text: 'Copy'
            },
            {
                text: 'Paste'
            }]
        };
    }
}
</script>

Adding CSS Reference

Add ContextMenu component’s styles as given below in <style> section of the App.vue file.

<style>
@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-popups/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;
}
</style>

Run the application

export default {
    data () {
        return {
            menuItems:[
            {
                text: 'Cut'
            },
            {
                text: 'Copy'
            },
            {
                text: 'Paste'
            }]
        };
    }
}
</script>

<style>
@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-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-navigations/styles/material.css";

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

Rendering items with Separator

The Separators are the horizontal lines that are used to separate the menu items. You cannot select the separators. You can enable separators to group the menu items using the separator property. Cut, Copy, and Paste menu items are grouped using the separator property in the following sample.
