## Usage
Use a `v-model` to display a searchable and selectable list of commands.

#default
:command-palette-example-basic{class="h-[257px]"}
#code
```vue
<script setup>
const people = [
{ id: 1, label: 'Wade Cooper' },
{ id: 2, label: 'Arlene Mccoy' },
{ id: 3, label: 'Devon Webb' },
{ id: 4, label: 'Tom Cook' },
{ id: 5, label: 'Tanya Fox' },
{ id: 6, label: 'Hellen Schmidt' },
{ id: 7, label: 'Caroline Schultz' },
{ id: 8, label: 'Mason Heaney' },
{ id: 9, label: 'Claudie Smitham' },
{ id: 10, label: 'Emil Schaefer' }
]
const selected = ref([people[3]])
</script>
<template>
<UCommandPalette
v-model="selected"
multiple
nullable
:groups="[{ key: 'people', commands: people }]"
:fuse="{ resultLimit: 6, fuseOptions: { threshold: 0.1 } }"
/>
</template>
```

You can put a `CommandPalette` anywhere you want but it's most commonly used inside of a modal.
::component-example
#default
:command-palette-example-modal
#code
```vue
<script setup>
const isOpen = ref(false)
const people = [
{ id: 1, label: 'Wade Cooper' },
{ id: 2, label: 'Arlene Mccoy' },
{ id: 3, label: 'Devon Webb' },
{ id: 4, label: 'Tom Cook' },
{ id: 5, label: 'Tanya Fox' },
{ id: 6, label: 'Hellen Schmidt' },
{ id: 7, label: 'Caroline Schultz' },
{ id: 8, label: 'Mason Heaney' },
{ id: 9, label: 'Claudie Smitham' },
{ id: 10, label: 'Emil Schaefer' }
]
const selected = ref([])
</script>
<template>
<div>
<UButton label="Open" @click="isOpen = true" />
<UModal v-model="isOpen">
<UCommandPalette
v-model="selected"
multiple
nullable
:groups="[{ key: 'people', commands: people }]"
/>
</UModal>
</div>
</template>
```
::
You can pass multiple groups of commands to the component. Each group will be separated by a divider and will display a label.
Without a `v-model`, you can also listen on `@update:model-value` to navigate to a link or do something else when a command is clicked.

### 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 `selected-icon` prop to set a different icon or change it globally in `ui.commandPalette.default.selectedIcon`. Defaults to `i-heroicons-check-20-solid`.
::component-card
---
padding: false
baseProps:
emptyState: null
props:
icon: 'i-heroicons-command-line'
excludedProps:
- icon
---
::
### Loading
Use the `loading` prop to show a loading icon.
Use the `loading-icon` prop to set a different icon or change it globally in `ui.commandPalette.default.loadingIcon`. Defaults to `i-heroicons-arrow-path-20-solid`.
::component-card
---
padding: false
baseProps:
emptyState: null
props:
loading: true
excludedProps:
- icon
---
::
### Placeholder
Use the `placeholder` prop to change the input placeholder
::component-card
---
padding: false
baseProps:
emptyState: null
props:
placeholder: 'Type a command...'
excludedProps:
- icon
---
::
### Close
Use the `close-button` prop to display a close button on the right side of the input.
You can pass all the props of the [Button](/elements/button) component to customize it through the `close-button` prop or globally through `ui.commandPalette.default.closeButton`.
::component-card
---
padding: false
baseProps:
emptyState: null
props:
closeButton:
icon: 'i-heroicons-x-mark-20-solid'
color: 'gray'
variant: 'link'
padded: false
excludedProps:
- closeButton
---
::
### Empty
An empty state will be displayed when there are no results.
Use the `empty-state` prop to customize the `icon` and `label` or change them globally in `ui.commandPalette.default.emptyState`.
You can also set it to `null` to hide the empty state.
::component-card
---
padding: false
baseProps:
placeholder: 'Type something to see the empty label change'
props:
emptyState:
icon: 'i-heroicons-magnifying-glass-20-solid'
label: "We couldn't find any items."
queryLabel: "We couldn't find any items with that term. Please try again."
excludedProps:
- emptyState

## Full-text search
The CommandPalette component takes care of the full-text search for you with [Fuse.js](https://fusejs.io). You can pass all the options of Fuse.js through the `fuse` prop.
When searching for a command, the component will look for a `label` property on the command by default. You can customize this behavior by overriding the `command-attribute` prop. This will also affect the display of the command.
You can also highlight the matches in the command by setting the `fuse.fuseOptions.includeMatches` to `true`. The CommandPalette component automatically takes care of the highlighting for you.
```vue
<template>
<UCommandPalette
command-attribute="title"
:fuse="{
fuseOptions: {
ignoreLocation: true,
includeMatches: true,
threshold: 0,
keys: ['title', 'description', 'children.children.value', 'children.children.children.value']
},
resultLimit: 10
}"
/>
</template>
```
::callout{icon="i-heroicons-light-bulb"}
Try it yourself in this documentation's search by pressing :kbd{value="meta"} :kbd{value="K" class="ml-1"}.
::
## Async search
You can also pass an `async` function to the `search` property of a group to perform an async search. The function will receive the query as its first argument and should return an array of commands.
::component-example
---
padding: false
---
#default
:command-palette-example-async{class="h-[274px]"}
#code
```vue
<script setup>
const groups = computed(() => {
return [{
key: 'users',
label: q => q && `Users matching “${q}”...`,
search: async (q) => {
if (!q) {
return []
}
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)
})
</script>
<template>
<UCommandPalette :groups="groups" />
</template>
```
::
::callout{icon="i-heroicons-light-bulb"}
The `loading` state will automatically be enabled when a `search` function is loading. You can disable this behavior by setting the `loading-icon` prop to `null` or globally in `ui.commandPalette.default.loadingIcon`.
::
## Slots
### `<group>-icon`
Use the `#<group>-icon` slot to override the left command content which display by default the `icon`, `avatar` and `chip`.
### `<group>-command`
Use the `#<group>-command` slot to override the command content which display by default the `prefix`, `suffix` and `label` (customizable through the `command-attribute` prop).
### `<group>-active`
Use the `#<group>-active` slot to override the right command content (when hovered) which display by default the `active` field of the group if provided.
### `<group>-inactive`
Use the `#<group>-inactive` slot to override the right command content (when not hovered) which display by default the `inactive` field of the group if provided or the `shortcuts` of the command.
::callout{icon="i-heroicons-light-bulb"}
The 4 slots above will have access to the `group`, `command`, `active` and `selected` properties in the slot scope.
::
### `empty-state`
Use the `#empty-state` slot to customize the empty state.
