Change menu items dynamically in Vue ContextMenu component

17 Mar 2023 / 2 minutes to read

The items visible in the ContextMenu can be changed dynamically based on the target in which you open the ContextMenu. To achieve this behavior, initialize ContextMenu with all items using items property and then based on the context you open hide/show required items using hideItems/ showItems method in beforeOpen event.

In the following example, the datasource for Clipboard div is Cut, Copy, Paste and for the Editor div is Add, Edit, Delete is changed on beforeOpen event using hideItems and showItems method.

Copied to clipboard
    <div id="target">
        <div id='left' class='e-div'>Clipboard</div>
        <div id='right' class='e-div'>Editor</div>
    <ejs-contextmenu id='cmenu' target='#target' :items='menuItems' :beforeOpen="onBeforeOpen"></ejs-contextmenu>

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