Usage

The SelectMenu component renders by default a Select component and is based on the ui.select preset. You can use most of the Select props to configure the display if you don't want to override the default slot such as color, variant, size, placeholder, icon, disabled, etc.

Like the Select component, you can use the options prop to pass an array of strings or objects.

::component-example #default :select-menu-example-basic{class="w-full lg:w-40"}

#code

<script setup>
const people = ['Wade Cooper', 'Arlene Mccoy', 'Devon Webb', 'Tom Cook', 'Tanya Fox', 'Hellen Schmidt', 'Caroline Schultz', 'Mason Heaney', 'Claudie Smitham', 'Emil Schaefer']

const selected = ref(people[0])
</script>

<template>
  <USelectMenu v-model="selected" :options="people" />
</template>

::

Multiple

You can use the multiple prop to select multiple values.

::component-example #default :select-menu-example-multiple{class="w-full lg:w-40"}

#code

<script setup>
const people = [...]

const selected = ref([])
</script>

<template>
  <USelectMenu v-model="selected" :options="people" multiple placeholder="Select people" />
</template>

::

Objects

You can pass an array of objects to options and either compare on the whole object or use the by prop to compare on a specific key. You can configure which field will be used to display the label through the option-attribute prop that defaults to label.

::component-example #default :select-menu-example-objects{class="w-full lg:w-40"} #code

<script setup>
const people = [{
  id: 'benjamincanac',
  label: 'benjamincanac',
  href: 'https://github.com/benjamincanac',
  target: '_blank',
  avatar: { src: 'https://avatars.githubusercontent.com/u/739984?v=4' }
},
{
  id: 'Atinux',
  label: 'Atinux',
  href: 'https://github.com/Atinux',
  target: '_blank',
  avatar: { src: 'https://avatars.githubusercontent.com/u/904724?v=4' }
},
{
  id: 'smarroufin',
  label: 'smarroufin',
  href: 'https://github.com/smarroufin',
  target: '_blank',
  avatar: { src: 'https://avatars.githubusercontent.com/u/7547335?v=4' }
},
{
  id: 'nobody',
  label: 'Nobody',
  icon: 'i-heroicons-user-circle'
}]

const selected = ref(people[0])
</script>

<template>
  <USelectMenu v-model="selected" :options="people">
    <template #label>
      <UIcon v-if="selected.icon" :name="selected.icon" class="w-4 h-4" />
      <UAvatar v-else-if="selected.avatar" v-bind="selected.avatar" size="3xs" />

      {{ selected.label }}
    </template>
  </USelectMenu>
</template>

::

If you only want to select a single object property rather than the whole object as value, you can set the value-attribute property. This prop defaults to null.

::component-example #default :select-menu-example-objects-value-attribute{class="w-full lg:w-40"}

#code

<script setup>
const people = [{
  id: 1,
  name: 'Wade Cooper'
}, {
  id: 2,
  name: 'Arlene Mccoy'
}, {
  id: 3,
  name: 'Devon Webb'
}, {
  id: 4,
  name: 'Tom Cook'
}]

const selected = ref(people[0].id)

const current = computed(() => people.find(person => person.id === selected.value))
</script>

<template>
  <USelectMenu
    v-model="selected"
    :options="people"
    placeholder="Select people"
    value-attribute="id"
    option-attribute="name"
  >
    <template #label>
      {{ current.name }}
    </template>
  </USelectMenu>
</template>

::

Icon

Use the selected-icon prop to set a different icon or change it globally in ui.selectMenu.default.selectedIcon. Defaults to i-heroicons-check-20-solid.

::component-card

baseProps: class: 'w-full lg:w-40' placeholder: 'Select a person' options: ['Wade Cooper', 'Arlene Mccoy', 'Devon Webb', 'Tom Cook', 'Tanya Fox', 'Hellen Schmidt', 'Caroline Schultz', 'Mason Heaney', 'Claudie Smitham', 'Emil Schaefer'] props: selectedIcon: 'i-heroicons-hand-thumb-up-solid' excludedProps:

  • selectedIcon

::callout{icon="i-heroicons-light-bulb"} Learn how to customize icons from the Select component. ::

Use the searchable prop to enable search.

Use the searchable-placeholder prop to set a different placeholder.

This will use Headless UI Combobox component instead of Listbox.

::component-card

baseProps: class: 'w-full lg:w-40' placeholder: 'Select a person' options: ['Wade Cooper', 'Arlene Mccoy', 'Devon Webb', 'Tom Cook', 'Tanya Fox', 'Hellen Schmidt', 'Caroline Schultz', 'Mason Heaney', 'Claudie Smitham', 'Emil Schaefer'] props: searchable: true searchablePlaceholder: 'Search a person...'

::

Pass a function to the searchable prop to customize the search behavior and filter options according to your needs. The function will receive the query as its first argument and should return an array.

Use the debounce prop to adjust the delay of the function.

::component-example #default :select-menu-example-async-search{class="w-full lg:w-40"}

#code

<script setup>
const search = async (q) => {
  const users = await $fetch('https://jsonplaceholder.typicode.com/users', { params: { q } })

  return users.map(user => ({ id: user.id, label: user.name, suffix: user.email })).filter(Boolean)
}

const selected = ref([])
</script>

<template>
  <USelectMenu
    v-model="selected"
    :searchable="search"
    placeholder="Search for a user..."
    multiple
    by="id"
  />
</template>

::

Create option

Use the creatable prop to enable the creation of new options when the search doesn't return any results (only works with searchable).

Try to search for something that doesn't exist in the example below.

::component-example #default :select-menu-example-creatable{class="w-full lg:w-40"}

#code

<script setup>
const options = ref([
  { id: 1, name: 'bug', color: 'd73a4a' },
  { id: 2, name: 'documentation', color: '0075ca' },
  { id: 3, name: 'duplicate', color: 'cfd3d7' },
  { id: 4, name: 'enhancement', color: 'a2eeef' },
  { id: 5, name: 'good first issue', color: '7057ff' },
  { id: 6, name: 'help wanted', color: '008672' },
  { id: 7, name: 'invalid', color: 'e4e669' },
  { id: 8, name: 'question', color: 'd876e3' },
  { id: 9, name: 'wontfix', color: 'ffffff' }
])

const selected = ref([])

const labels = computed({
  get: () => selected.value,
  set: async (labels) => {
    const promises = labels.map(async (label) => {
      if (label.id) {
        return label
      }

      // In a real app, you would make an API call to create the label
      const response = {
        name: label.name,
        color: generateColorFromString(label.name)
      }

      options.value.push(response)

      return response
    })

    selected.value = await Promise.all(promises)
  }
})

// Look at the component example to see how this is used
function generateColorFromString (str) {
  // ...
}
</script>
