Examples

Binding objects as values

Unlike native HTML form controls which only allow you to provide strings as values, radix-vue supports binding complex objects as well.

vue
<script setup lang="ts">
import { ref } from 'vue'
import { ComboboxContent, ComboboxInput, ComboboxItem, ComboboxPortal, ComboboxRoot } from 'radix-vue'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]
const selectedPeople = ref(people[0])
</script>

<template>
  <ComboboxRoot v-model="selectedPeople">
    <ComboboxInput />
    <ComboboxPortal>
      <ComboboxContent>
        <ComboboxItem
          v-for="person in people"
          :key="person.id"
          :value="person"
          :disabled="person.unavailable"
        >
          {{ person.name }}
        </ComboboxItem>
      </ComboboxContent>
    </ComboboxPortal>
  </ComboboxRoot>
</template>

Selecting multiple values

The Combobox component allows you to select multiple values. You can enable this by providing an array of values instead of a single value.

vue
<script setup lang="ts">
import { ref } from 'vue'
import { ComboboxRoot } from 'radix-vue'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]
const selectedPeople = ref([people[0], people[1]])
</script>

<template>
  <ComboboxRoot v-model="selectedPeople" multiple>
    ...
  </ComboboxRoot>
</template>

Custom filtering

Internally, ComboboxRoot would apply default filter function to filter relevant ComboboxItem (only apply when modelValue is type string).

However this behavior can be replaced using 2 different method.

1. Provide filter-function props.

vue
<script setup lang="ts">
import { ref } from 'vue'
import { ComboboxContent, ComboboxInput, ComboboxItem, ComboboxPortal, ComboboxRoot } from 'radix-vue'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]
const selectedPeople = ref(people[0])

function filterFunction(list: typeof people[number], searchTerm: string) {
  return list.filter((person) => {
    return person.name.toLowerCase().includes(searchTerm.toLowerCase())
  })
}
</script>

<template>
  <ComboboxRoot
    v-model="selectedPeople"
    :filter-function="filterFunction"
  >
    <ComboboxInput />
    <ComboboxPortal>
      <ComboboxContent>
        <ComboboxItem
          v-for="person in people"
          :key="person.id"
          :value="person"
          :disabled="person.unavailable"
        >
          {{ person.name }}
        </ComboboxItem>
      </ComboboxContent>
    </ComboboxPortal>
  </ComboboxRoot>
</template>

2. Filtered v-for options

vue
<script setup lang="ts">
import { ref } from 'vue'
import { ComboboxContent, ComboboxInput, ComboboxItem, ComboboxPortal, ComboboxRoot } from 'radix-vue'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]
const selectedPeople = ref(people[0])
const searchTerm = ref('')

const filteredPeople = computed(() =>
  searchTerm.value === ''
    ? people
    : people.filter((person) => {
      return person.name.toLowerCase().includes(searchTerm.value.toLowerCase())
    })
)
</script>

<template>
  <ComboboxRoot
    v-model="selectedPeople"
    v-model:searchTerm="searchTerm"
  >
    <ComboboxInput />
    <ComboboxPortal>
      <ComboboxContent>
        <ComboboxItem
          v-for="person in filteredPeople"
          :key="person.id"
          :value="person"
          :disabled="person.unavailable"
        >
          {{ person.name }}
        </ComboboxItem>
      </ComboboxContent>
    </ComboboxPortal>
  </ComboboxRoot>
</template>

Custom label

By default the Combobox will use the input contents as the label for screenreaders. If you'd like more control over what is announced to assistive technologies, use the Label component.

vue
<script setup lang="ts">
import { ref } from 'vue'
import { ComboboxInput, ComboboxRoot, Label } from 'radix-vue'
</script>

<template>
  <ComboboxRoot v-model="selectedPeople">
    <Label for="person">Person: </Label>
    <ComboboxInput id="person" placeholder="Select a person" />
    ...
  </ComboboxRoot>
</template>

With disabled items

You can add special styles to disabled items via the data-disabled attribute.

vue
<script setup lang="ts">
import { ref } from 'vue'
import {
  ComboboxContent,
  ComboboxInput,
  ComboboxItem,
  ComboboxPortal,
  ComboboxRoot,
} from 'radix-vue'
</script>

<template>
  <ComboboxRoot>
    <ComboboxInput />
    <ComboboxPortal>
      <ComboboxContent>
        <ComboboxItem class="ComboboxItem" disabled>
          ...
        </ComboboxItem>
      </ComboboxContent>
    </ComboboxPortal>
  </ComboboxRoot>
</template>
css
/* styles.css */
.ComboboxItem[data-disabled] {
  color: "gainsboro";
}

With separators

Use the Separator part to add a separator between items.

vue
<script setup lang="ts">
import { ref } from 'vue'
import {
  ComboboxContent,
  ComboboxInput,
  ComboboxItem,
  ComboboxPortal,
  ComboboxRoot,
  ComboboxSeparator
} from 'radix-vue'
</script>

<template>
  <ComboboxRoot>
    <ComboboxInput />
    <ComboboxPortal>
      <ComboboxContent>
        <ComboboxItem></ComboboxItem>
        <ComboboxItem></ComboboxItem>
        <ComboboxItem></ComboboxItem>
        <ComboboxSeparator />
        <ComboboxItem></ComboboxItem>
        <ComboboxItem></ComboboxItem>
        <ComboboxItem></ComboboxItem>
      </ComboboxContent>
    </ComboboxPortal>
  </ComboboxRoot>
</template>

With grouped items

Use the Group and Label parts to group items in a section.

vue
<script setup lang="ts">
import { ref } from 'vue'
import {
  ComboboxContent,
  ComboboxGroup,
  ComboboxInput,
  ComboboxItem,
  ComboboxLabel,
  ComboboxPortal,
  ComboboxRoot
} from 'radix-vue'
</script>

<template>
  <ComboboxRoot>
    <ComboboxInput />
    <ComboboxPortal>
      <ComboboxContent>
        <ComboboxGroup>
          <ComboboxLabel>Label</ComboboxLabel>
          <ComboboxItem></ComboboxItem>
          <ComboboxItem></ComboboxItem>
          <ComboboxItem></ComboboxItem>
        </ComboboxGroup>
      </ComboboxContent>
    </ComboboxPortal>
  </ComboboxRoot>
</template>

With complex items

You can use custom content in your items.

vue
<script setup lang="ts">
import { ref } from 'vue'
import {
  ComboboxContent,
  ComboboxGroup,
  ComboboxInput,
  ComboboxItem,
  ComboboxItemIndicator,
  ComboboxLabel,
  ComboboxPortal,
  ComboboxRoot
} from 'radix-vue'
</script>

<template>
  <ComboboxRoot>
    <ComboboxInput />
    <ComboboxPortal>
      <ComboboxContent>
        <ComboboxItem>
          <img src="">
          Adolfo Hess
          <ComboboxItemIndicator />
        </ComboboxItem>

      </ComboboxContent>
    </ComboboxPortal>
  </ComboboxRoot>
</template>
