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.
// index.vue
<script setup lang="ts">
import {
SelectContent,
SelectGroup,
SelectItem,
SelectItemIndicator,
SelectLabel,
SelectPortal,
SelectRoot,
SelectSeparator,
SelectTrigger,
} from 'reka-ui'
</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 --reka-select-trigger-width
and --reka-select-content-available-height
to support this. Use them to constrain the content dimensions.
// index.vue
<script setup lang="ts">
import {
SelectContent,
SelectGroup,
SelectItem,
SelectItemIndicator,
SelectLabel,
SelectPortal,
SelectRoot,
SelectSeparator,
SelectTrigger,
} from 'reka-ui'
</script>
<template>
<SelectRoot>
<SelectTrigger>…</SelectTrigger>
<SelectPortal>
<SelectContent
class="SelectContent"
position="popper"
:side-offset="5"
>
…
</SelectContent>
</SelectPortal>
</SelectRoot>
</template>
/* styles.css */
.SelectContent {
width: var(--reka-select-trigger-width);
max-height: var(--reka-select-content-available-height);
}
With disabled items
You can add special styles to disabled items via the data-disabled
attribute.
// index.vue
<script setup lang="ts">
import {
SelectContent,
SelectGroup,
SelectItem,
SelectItemIndicator,
SelectLabel,
SelectPortal,
SelectRoot,
SelectSeparator,
SelectTrigger,
} from 'reka-ui'
</script>
<template>
<SelectRoot>
<SelectTrigger>…</SelectTrigger>
<SelectPortal>
<SelectContent>
<SelectViewport>
<SelectItem
class="SelectItem"
disabled
>
…
</SelectItem>
<SelectItem>…</SelectItem>
<SelectItem>…</SelectItem>
</SelectViewport>
</SelectContent>
</SelectPortal>
</SelectRoot>
</template>
/* 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.
// index.vue
<script setup lang="ts">
import {
SelectContent,
SelectGroup,
SelectItem,
SelectItemIndicator,
SelectLabel,
SelectPortal,
SelectRoot,
SelectSeparator,
SelectTrigger,
} from 'reka-ui'
import './styles.css'
</script>
<template>
<SelectRoot>
<SelectTrigger class="SelectTrigger">
<SelectValue placeholder="Pick an option" />
<SelectIcon />
</SelectTrigger>
<SelectPortal>
<SelectContent>…</SelectContent>
</SelectPortal>
</SelectRoot>
</template>
/* styles.css */
.SelectTrigger[data-placeholder] {
color: "gainsboro";
}
With separators
Use the Separator
part to add a separator between items.
<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.
<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.
<script setup lang="ts">
import {
SelectContent,
SelectGroup,
SelectItem,
SelectItemIndicator,
SelectLabel,
SelectPortal,
SelectRoot,
SelectSeparator,
SelectTrigger,
} from 'reka-ui'
</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 choosing 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.
<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.
// index.vue
<script setup lang="ts">
import {
ScrollAreaRoot,
ScrollAreaScrollbar,
ScrollAreaThumb,
ScrollAreaViewport,
SelectContent,
SelectGroup,
SelectItem,
SelectItemIndicator,
SelectLabel,
SelectPortal,
SelectRoot,
SelectSeparator,
SelectTrigger,
} from 'reka-ui'
</script>
<template>
<SelectRoot>
<SelectTrigger>…</SelectTrigger>
<SelectPortal>
<SelectContent>
<ScrollAreaRoot
class="ScrollAreaRoot"
type="auto"
>
<SelectViewport as-child>
<ScrollAreaViewport class="ScrollAreaViewport">

<StyledItem>…</StyledItem>
</ScrollAreaViewport>
</SelectViewport>
<ScrollAreaScrollbar
class="ScrollAreaScrollbar"
orientation="vertical"
>
<ScrollAreaThumb class="ScrollAreaThumb" />
</ScrollAreaScrollbar>
</ScrollAreaRoot>
</SelectContent>
</SelectPortal>
</SelectRoot>
</template>
/* 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.

SelectItem,
SelectItemIndicator,
SelectLabel,
SelectPortal,
