Nuxt Headless UI CircleCI

npm version npm downloads License Nuxt

Headless UI integration for Nuxt. Completely unstyled, fully accessible UI components, designed to integrate beautifully with Tailwind CSS.

Headless UI documentation for Vue: https://headlessui.com/vue/menu

Features

  • Automatic dynamic imports (no global components)
  • Fully type safe
  • Configurable component prefix (defaults to Headless)

Quick Setup

  1. Add nuxt-headlessui dependency to your project
npx nuxi@latest module add headlessui
  1. Add nuxt-headlessui to the modules section of nuxt.config.ts
{
    modules: [
        'nuxt-headlessui'
    ],

    // Optionally change the default prefix.
    headlessui: {
        prefix: 'Headless'
    }
}
  1. Add the following lines to your app.vue file inside <script setup>:

Note

This is only needed if you use versions prior to vue@3.5.0 or @headlessui/vue@1.7.23. More recent versions use the native useId composable provided by Vue.

// Use SSR-safe IDs for Headless UI
provideHeadlessUseId(() => useId())

This is required to avoid hydration issues, because of id mismatches. Both composables will be auto-imported by nuxt. The provideHeadlessUseId composable is an alias for the provideUseId composable from @headlessui/vue. import { provideUseId } from '@headlessui/vue' directly won't work out of the box.

That's it! You can now use Headless UI in your Nuxt app ✨

Usage

After completing setup, simply use the headless components in your components and pages and style them with your favourite CSS framework. You don't have to import the components. Here is an example of a Listbox (Select), which uses heroicons and Tailwind CSS:

<template>
  <div class="container mx-auto">
    <div class="w-72">
      <HeadlessListbox v-model="selectedPerson">
        <div class="relative mt-1">
          <HeadlessListboxButton
            class="relative w-full cursor-default rounded-lg bg-white py-2 pl-3 pr-10 text-left shadow-md focus:outline-none focus-visible:border-indigo-500 focus-visible:ring-2 focus-visible:ring-white focus-visible:ring-opacity-75 focus-visible:ring-offset-2 focus-visible:ring-offset-orange-300 sm:text-sm"
          >
            <span class="block truncate">{{ selectedPerson.name }}</span>
            <span
              class="pointer-events-none absolute inset-y-0 right-0 flex items-center pr-2"
            >
              <ChevronUpDownIcon
                class="h-5 w-5 text-gray-400"
                aria-hidden="true"
              />
            </span>
          </HeadlessListboxButton>

          <transition
            leave-active-class="transition duration-100 ease-in"
            leave-from-class="opacity-100"
            leave-to-class="opacity-0"
          >
            <HeadlessListboxOptions
              class="absolute mt-1 max-h-60 w-full overflow-auto rounded-md bg-white py-1 text-base shadow-lg ring-1 ring-black ring-opacity-5 focus:outline-none sm:text-sm"
            >
              <HeadlessListboxOption
                v-for="person in people"
                v-slot="{ active, selected }"
                :key="person.name"
                :value="person"
                as="template"
              >
                <li
                  :class="[
                    active ? 'bg-amber-100 text-amber-900' : 'text-gray-900',
                    'relative cursor-default select-none py-2 pl-10 pr-4',
                  ]"
                >
                  <span
                    :class="[
                      selected ? 'font-medium' : 'font-normal',
                      'block truncate',
                    ]"
                  >{{ person.name }}</span>
                  <span
                    v-if="selected"
                    class="absolute inset-y-0 left-0 flex items-center pl-3 text-amber-600"
                  >
                    <CheckIcon class="h-5 w-5" aria-hidden="true" />
                  </span>
                </li>
              </HeadlessListboxOption>
            </HeadlessListboxOptions>
          </transition>
        </div>
      </HeadlessListbox>
    </div>
  </div>
</template>

<script setup>
import { ref } from 'vue'
import { CheckIcon, ChevronUpDownIcon } from '@heroicons/vue/20/solid'

const people = [
  { name: 'Wade Cooper' },
  { name: 'Arlene Mccoy' },
  { name: 'Devon Webb' },
  { name: 'Tom Cook' },
  { name: 'Tanya Fox' },
  { name: 'Hellen Schmidt' }
]
const selectedPerson = ref(people[0])
</script>

If you are using Tailwind CSS, you can use the @headlessui/tailwindcss plugin to get modifiers like ui-open:* and ui-active:*. There is a [unocss primitives preset]https://github.com/zirbest/unocss-preset-primitives/tree/main) which does this in case if you are using UnoCss.
