TieredMenu is inline by default whereas popup mode is supported by enabling popup property and calling toggle method with an event of the target.
<Button type="button" label="Toggle" @click="toggle" />
<TieredMenu ref="menu" :model="items" :popup="true" />
toggle(event) {
this.$refs.menu.toggle(event);
}
TieredMenu offers content customization with the item template that receives the menuitem instance from the model as a parameter.
<TieredMenu :model="items">
<template #item="{item}">
<a :href="item.url">{{item.label}}</a>
</template>
</TieredMenu>
router-link with route configuration can also be used within templating for further customization.
<TieredMenu :model="items">
<template #item="{item}">
<router-link :to="item.to" custom v-slot="{href, route, navigate, isActive, isExactActive}">
<a :href="href" @click="navigate" :class="{'active-link': isActive, 'active-link-exact': isExactActive}">{{route.fullPath}}</a>
</router-link>
</template>
</TieredMenu>

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