## Usage
The SelectMenu component renders by default a [Select](/forms/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 [size](/forms/select#size), [placeholder](/forms/select#placeholder), [appearance](/forms/select#appearance), [icon](/forms/select#icon), [disabled](/forms/select#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="max-w-[12rem] w-full"}
#code
```vue
<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>
```
::
You can use the `multiple` prop to select multiple values but you have to override the `#label` slot and handle the display yourself.
::component-example
#default
:select-menu-example-multiple{class="max-w-[12rem] w-full"}
#code
```vue
<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([])
</script>
<template>
<USelectMenu v-model="selected" :options="people" multiple>
<template #label>
<span v-if="selected.length" class="font-medium truncate">{{ selected.join(', ') }}</span>
<span v-else class="block truncate text-gray-400 dark:text-gray-500">Select people</span>
</template>
</USelectMenu>
</template>
```
::
You can also override the default slot entirely.
::component-example
#default
:select-menu-example-button{class="max-w-[12rem] w-full"}
#code
```vue
<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[3])
</script>
<template>
<USelectMenu v-slot="{ open }" v-model="selected" :options="people">
<UButton>
{{ selected }}
<UIcon name="i-heroicons-chevron-right-20-solid" class="w-5 h-5 transition-transform" :class="[open && 'transform rotate-90']" />
</UButton>
</USelectMenu>
</template>
```
::
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 `optionAttribute` prop that defaults to `label`.
::component-example
#default
:select-menu-example-objects{class="max-w-[12rem] w-full"}
#code
```vue
<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' }

label: '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>
```

### Icon
Use any icon from [Iconify](https://icones.js.org) by setting the `icon` prop by using this pattern: `i-{collection_name}-{icon_name}`.
Use the `trailingIcon` prop to set a different icon or change it globally in `ui.select.default.trailingIcon`. Defaults to `i-heroicons-chevron-down-20-solid`.
Use the `selectedIcon` prop to set a different icon or change it globally in `ui.selectMenu.default.selectedIcon`. Defaults to `i-heroicons-check-20-solid`.

### Search
