MegaMenu requires a collection of menuitems as its model.


<MegaMenu :model="items" />

Layout of the MegaMenu is configured with the orientation property that accepts horizontal and vertical as options.


<MegaMenu :model="items" orientation="vertical" />

MegaMenu offers item customization with the item template that receives the menuitem instance from the model as a parameter. Additional slots named start and end are provided to embed content before or after the menu.


<MegaMenu :model="items" class="p-4 bg-surface-0" style="border-radius: 3rem">

        </svg>

            <span class="inline-flex flex-col gap-1">
                <span class="font-bold text-lg">{{ item.label }}</span>
                <span class="whitespace-nowrap">{{ item.subtext }}</span>
            </span>
        </a>
        <div v-else class="flex flex-col items-start gap-4 p-2">
            <img alt="megamenu-demo" :src="item.image" class="w-full" />
            <span>{{ item.subtext }}</span>
            <Button :label="item.label" outlined />

    </template>
    <template #end>
        <Avatar image="/images/avatar/amyelsner.png" shape="circle" />

Command #

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


{
    label: 'Log out',
    icon: 'pi pi-signout',
    command: () => {
        // Callback to run
    }
}

Router #

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


<MegaMenu :model="items">
    <template #item="{ item }">
        <router-link v-if="item.route" v-slot="{ href, navigate }" :to="item.route" custom>
            <a v-ripple :href="href" @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">
            <span :class="item.icon" />
            <span class="ml-2">{{ item.label }}</span>
        </a>
    </template>
</MegaMenu>

Accessibility #

Screen Reader

MegaMenu component uses the menubar role along with aria-orientation and the value to describe the component 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 MegaMenu uses the menu role with an aria-labelledby defined as the id of the submenu root menuitem label. In addition, root menuitems that open a submenu have aria-haspopup and aria-expanded to define the relation between the item and the submenu.
