TieredMenu

TieredMenu displays submenus in nested overlays.

Import #


import TieredMenu from 'primevue/tieredmenu';

Basic #

TieredMenu requires a collection of menuitems as its model.


<TieredMenu :model="items" />

Popup #

Overlay mode is enabled by adding popup property and calling toggle function of the menu ref with an event of the target.


<Button type="button" label="Toggle" @click="toggle" aria-haspopup="true" aria-controls="overlay_tmenu" />
<TieredMenu ref="menu" id="overlay_tmenu" :model="items" popup />

Template #

TieredMenu offers item customization with the item template that receives the menuitem instance from the model as a parameter.


<TieredMenu :model="items">
    <template #item="{ item, props, hasSubmenu }">
        <a v-ripple class="flex items-center" v-bind="props.action">
            <span :class="item.icon" />
            <span class="ml-2">{{ item.label }}</span>
            <Badge v-if="item.badge" class="ml-auto" :value="item.badge" />
            <span v-if="item.shortcut" class="ml-auto border border-surface rounded bg-emphasis text-muted-color text-xs p-1">{{ item.shortcut }}</span>
            <i v-if="hasSubmenu" class="pi pi-angle-right ml-auto"></i>
        </a>
    </template>
</TieredMenu>

Command #

The command property defines the callback to run when an item is activated by click or a key event.


<TieredMenu :model="items" />
<Toast />

Router #

Items with navigation are defined with templating to be able to use a router link component, an external link or programmatic navigation.


<TieredMenu :model="items">
    <template #item="{ item, props, hasSubmenu }">
        <router-link v-if="item.route" v-slot="{ href, navigate }" :to="item.route" custom>
            <a v-ripple :href="href" v-bind="props.action" @click="navigate">
                <span :class="item.icon" />
                <span class="ml-2">{{ item.label }}</span>
            </a>
        </router-link>
        <a v-else v-ripple :href="item.url" :target="item.target" v-bind="props.action">
            <span :class="item.icon" />
            <span class="ml-2">{{ item.label }}</span>
            <span v-if="hasSubmenu" class="pi pi-angle-right ml-auto" />
        </a>
    </template>
</TieredMenu>

Accessibility #

Screen Reader

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.
