            <h5>MenuModel</h5>
            <p>ContextMenu uses the common MenuModel API to define the items, visit <router-link to="/menumodel">MenuModel API</router-link> for details.</p>

            <h5>Getting Started</h5>
            <p>ContextMenu requires a collection of menuitems as its model.</p>

            <pre v-code.script><code>
export default {
	data() {
			return {
					items: [
							{
				label:'File',
				icon:'pi pi-fw pi-file',
				items:[
					{
						label:'New',
						icon:'pi pi-fw pi-plus',
						items:[
							{
								label:'Bookmark',
								icon:'pi pi-fw pi-bookmark'

					}
				]
			},

				items:[

            <h5>Document Menu</h5>
            <p>Setting global property attaches the context menu to the document.</p>
            <pre v-code><code>
&lt;ContextMenu :global="true" :model="items" /&gt;

</code></pre>

            <h5>Element Menu</h5>
            <p>ContextMenu is attached to a custom element manually using the reference and calling the <i>show(event)</i> method.</p>

            <pre v-code><code>
&lt;img alt="logo" src="/demo/images/nature/nature3.jpg" @contextmenu="onImageRightClick"&gt;
&lt;ContextMenu ref="menu" :model="items" /&gt;

</code></pre>

            <pre v-code.script><code>
export default {
	data() {
			return {
					items: //items
			}
	},
	methods: {
			onImageRightClick(event) {
					this.$refs.menu.show(event);
			}
	}
}

</code></pre>

            <h5>Templating</h5>
            <p>ContextMenu offers content customization with the <i>item</i> template that receives the menuitem instance from the model as a parameter.</p>
            <pre v-code><code><template v-pre>
&lt;ContextMenu :model="items"&gt;
	&lt;template #item="{item}"&gt;
			&lt;a :href="item.url"&gt;{{item.label}}&lt;/a&gt;
	&lt;/template&gt;
&lt;/ContextMenu&gt;
</template>
</code></pre>

            <p><i>router-link</i> with route configuration can also be used within templating for further customization.</p>
            <pre v-code><code><template v-pre>
&lt;ContextMenu :model="items"&gt;
	&lt;template #item="{item}"&gt;
			&lt;router-link :to="item.to" custom v-slot="{href, route, navigate, isActive, isExactActive}"&gt;
					&lt;a :href="href" @click="navigate" :class="{'active-link': isActive, 'active-link-exact": isExactActive}&gt;{{route.fullPath}}&lt;/a&gt;
			&lt;/router-link&gt;
	&lt;/template&gt;
&lt;/ContextMenu&gt;
</template>
</code></pre>

            <h5>Properties</h5>
            <p>Any property as style and class are passed to the main container element. Following are the additional properties to configure the component.</p>

            <p>
                ContextMenu component uses the <i>menubar</i> role with <i>aria-orientation</i> set to "vertical" and the value to describe the menu can either be provided with <i>aria-labelledby</i> or <i>aria-label</i> props. Each list item has a
                <i>menuitem</i> role with <i>aria-label</i> referring to the label of the item and <i>aria-disabled</i> defined if the item is disabled. A submenu within a ContextMenu uses the <i>menu</i> role with an <i>aria-labelledby</i> defined
                as the id of the submenu root menuitem label. In addition, menuitems that open a submenu have <i>aria-haspopup</i>, <i>aria-expanded</i> and <i>aria-controls</i> to define the relation between the item and the submenu.
