Use case scenarios in Vue Menu component

16 Mar 202324 minutes to read

Scrollable menu

The menu component supports horizontal and vertical scrolling to render large menus and submenus in an adaptive way. This can be achieved by enabling the enableScrolling property and by restricting the corresponding menu/submenu size.

<template>
    <div>
        <ejs-menu :items='menuItems' :beforeOpen='onBeforeOpen' cssClass='e-scrollable-menu' :enableScrolling='true'></ejs-menu>
    </div>
</template>

<script>
import Vue from 'vue';

import { enableRipple, closest } from '@syncfusion/ej2-base';

enableRipple(true);
Vue.use(MenuPlugin);

The following example demonstrates how to integrate Menu with Toolbar component.

<template>
<div class="toolbar-menu-control">
<ejs-toolbar ref="toolbar" :created="onCreated">
    <e-items>
        <e-item :template='menuTemplate'></e-item>
        <e-item prefixIcon='em-icons e-shopping-cart' align='Right' ></e-item>
    </e-items>
</ejs-toolbar>
</div>
</template>

<script>
import Vue from 'vue';
import { MenuPlugin, ToolbarPlugin } from "@syncfusion/ej2-vue-navigations";
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);
Vue.use(MenuPlugin);
Vue.use(ToolbarPlugin);
