Examples ​

Change the positioning mode ​

By default, Select will behave similarly to a native MacOS menu by positioning SelectContent relative to the active item. If you would prefer an alternative positioning approach similar to Popover or DropdownMenu then you can set position to popper and make use of additional alignment options such as side, sideOffset and more.

vue
// index.vue
<script setup lang="ts">
import {
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectItemIndicator,
  SelectLabel,
  SelectPortal,
  SelectRoot,
  SelectSeparator,
  SelectTrigger,
} from 'radix-vue'
</script>

<template>
  <SelectRoot>
    <SelectTrigger>…</SelectTrigger>
    <SelectPortal>
      <SelectContent position="popper" :side-offset="5">
        …
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>

Constrain the content size ​

When using position="popper" on SelectContent, you may want to constrain the width of the content so that it matches the trigger width. You may also want to constrain its height to not exceed the viewport.

We expose several CSS custom properties such as --radix-select-trigger-width and --radix-select-content-available-height to support this. Use them to constrain the content dimensions.

vue
// index.vue
<script setup lang="ts">
import {
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectItemIndicator,
  SelectLabel,
  SelectPortal,
  SelectRoot,
  SelectSeparator,
  SelectTrigger,
} from 'radix-vue'
</script>

<template>
  <SelectRoot>
    <SelectTrigger>…</SelectTrigger>
    <SelectPortal>
      <SelectContent class="SelectContent" position="popper" :side-offset="5">
        …
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>
css
/* styles.css */
.SelectContent {
  width: var(--radix-select-trigger-width);
  max-height: var(--radix-select-content-available-height);
}

With disabled items ​

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

vue
// index.vue
<script setup lang="ts">
import {
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectItemIndicator,
  SelectLabel,
  SelectPortal,
  SelectRoot,
  SelectSeparator,
  SelectTrigger,
} from 'radix-vue'
</script>

<template>
  <SelectRoot>
    <SelectTrigger>…</SelectTrigger>
    <SelectPortal>
      <SelectContent>
        <SelectViewport>
          <SelectItem class="SelectItem" disabled>
            …
          </SelectItem>
          <SelectItem>…</SelectItem>
          <SelectItem>…</SelectItem>
        </SelectViewport>
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>
css
/* styles.css */
.SelectItem[data-disabled] {
  color: "gainsboro";
}

With a placeholder ​

You can use the placeholder prop on Value for when the select has no value. There's also a data-placeholder attribute on Trigger to help with styling.

vue
// index.vue
<script setup lang="ts">
import {
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectItemIndicator,
  SelectLabel,
  SelectPortal,
  SelectRoot,
  SelectSeparator,
  SelectTrigger,
} from 'radix-vue'
import './styles.css'
</script>

<template>
  <SelectRoot>
    <SelectTrigger class="SelectTrigger">
      <SelectValue placeholder="Pick an option" />
      <SelectIcon />
    </SelectTrigger>
    <SelectPortal>
      <SelectContent>…</SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>
css
/* styles.css */
.SelectTrigger[data-placeholder] {
  color: "gainsboro";
}

With separators ​

Use the Separator part to add a separator between items.

vue
<template>
  <SelectRoot>
    <SelectTrigger>…</SelectTrigger>
    <SelectPortal>
      <SelectContent>
        <SelectViewport>
          <SelectItem>…</SelectItem>
          <SelectItem>…</SelectItem>
          <SelectItem>…</SelectItem>
          <SelectSeparator />
          <SelectItem>…</SelectItem>
          <SelectItem>…</SelectItem>
        </SelectViewport>
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>

With grouped items ​

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

vue
<template>
  <SelectRoot>
    <SelectTrigger>…</SelectTrigger>
    <SelectPortal>
      <SelectContent>
        <SelectViewport>
          <SelectGroup>
            <SelectLabel>Label</SelectLabel>
            <SelectItem>…</SelectItem>
            <SelectItem>…</SelectItem>
            <SelectItem>…</SelectItem>
          </SelectGroup>
        </SelectViewport>
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>

With complex items ​

You can use custom content in your items.

vue
<script setup lang="ts">
import {
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectItemIndicator,
  SelectLabel,
  SelectPortal,
  SelectRoot,
  SelectSeparator,
  SelectTrigger,
} from 'radix-vue'
</script>

<template>
  <SelectRoot>
    <SelectTrigger>…</SelectTrigger>
    <SelectPortal>
      <SelectContent>
        <SelectViewport>
          <SelectItem>
            <SelectItemText>
              <img src="…">
              Adolfo Hess
            </SelectItemText>
            <SelectItemIndicator>…</SelectItemIndicator>
          </SelectItem>
          <SelectItem>…</SelectItem> <SelectItem>…</SelectItem>
        </SelectViewport>
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>

Controlling the value displayed in the trigger ​

By default the trigger will automatically display the selected item ItemText's content. You can control what appears by chosing to put things inside/outside the ItemText part.

If you need more flexibility, you can control the component using v-model props and passing slot to SelectValue. Remember to make sure what you put in there is accessible.

vue
<script setup>
const countries = { 'france': '🇫🇷', 'united-kingdom': '🇬🇧', 'spain': '🇪🇸' }

const value = ref('france')
</script>

<template>
  <SelectRoot v-model="value">
    <SelectTrigger>
      <SelectValue aria-label="value">
        {{ countries[value] }}
      </SelectValue>
      <SelectIcon />
    </SelectTrigger>
    <SelectPortal>
      <SelectContent>
        <SelectViewport>
          <SelectItem value="france">
            <SelectItemText>France</SelectItemText>
            <SelectItemIndicator>…</SelectItemIndicator>
          </SelectItem>
          <SelectItem value="united-kingdom">
            <SelectItemText>United Kingdom</SelectItemText>
            <SelectItemIndicator>…</SelectItemIndicator>
          </SelectItem>
          <SelectItem value="spain">
            <SelectItemText>Spain</SelectItemText>
            <SelectItemIndicator>…</SelectItemIndicator>
          </SelectItem>
        </SelectViewport>
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>

With custom scrollbar ​

The native scrollbar is hidden by default as we recommend using the ScrollUpButton and ScrollDownButton parts for the best UX. If you do not want to use these parts, compose your select with our Scroll Area primitive.

vue
// index.vue
<script setup lang="ts">
import {
  ScrollAreaRoot,
  ScrollAreaScrollbar,
  ScrollAreaThumb,
  ScrollAreaViewport,
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectItemIndicator,
  SelectLabel,
  SelectPortal,
  SelectRoot,
  SelectSeparator,
  SelectTrigger,
} from 'radix-vue'
</script>

<template>
  <SelectRoot>
    <SelectTrigger>…</SelectTrigger>
    <SelectPortal>
      <SelectContent>
        <ScrollAreaRoot class="ScrollAreaRoot" type="auto">
          <SelectViewport as-child>
            <ScrollAreaViewport class="ScrollAreaViewport">
              <StyledItem>…</StyledItem> <StyledItem>…</StyledItem>
              <StyledItem>…</StyledItem>
            </ScrollAreaViewport>
          </SelectViewport>
          <ScrollAreaScrollbar class="ScrollAreaScrollbar" orientation="vertical">
            <ScrollAreaThumb class="ScrollAreaThumb" />
          </ScrollAreaScrollbar>
        </ScrollAreaRoot>
      </SelectContent>
    </SelectPortal>
  </SelectRoot>
</template>
css
/* styles.css */
.ScrollAreaRoot {
  width: 100%;
  height: 100%;
}

.ScrollAreaViewport {
  width: 100%;
  height: 100%;
}

.ScrollAreaScrollbar {
  width: 4px;
  padding: 5px 2px;
}

.ScrollAreaThumb {
  background: rgba(0, 0, 0, 0.3);
  borderradius: 3px;
}

Accessibility ​

Adheres to the ListBox WAI-ARIA design pattern.

See the W3C Select-Only Combobox example for more information.

import {
  Label,
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectItemIndicator,
  SelectLabel,
  SelectPortal,
  SelectRoot,
  SelectSeparator,
  SelectTrigger,
} from 'radix-vue'
</script>

<template>
  <Label>
    Country
    <SelectRoot>…</SelectRoot>
  </Label>

  <!-- or -->

  <Label for="country">Country</Label>
  <SelectRoot>
    <SelectTrigger id="country">

Custom APIs ​

Create your own API by abstracting the primitive parts into your own component.

Abstract down to Select and SelectItem ​

This example abstracts most of the parts.
