⌘K

⌘K is a command menu React component that can also be used as an accessible combobox. You render items, it filters and sorts them automatically. ⌘K supports a fully composable API ^{^How?}, so you can wrap items in other components or even as static JSX.

Install

pnpm install cmdk

Use

import { Command } from 'cmdk'

const CommandMenu = () => {
  return (
    <Command label="Command Menu">
      <Command.Input />
      <Command.List>
        <Command.Empty>No results found.</Command.Empty>

        <Command.Group heading="Letters">
          <Command.Item>a</Command.Item>
          <Command.Item>b</Command.Item>
          <Command.Separator />
          <Command.Item>c</Command.Item>
        </Command.Group>

        <Command.Item>Apple</Command.Item>
      </Command.List>
    </Command>
  )
}

Or in a dialog:

import { Command } from 'cmdk'

const CommandMenu = () => {
  const [open, setOpen] = React.useState(false)

  // Toggle the menu when ⌘K is pressed
  React.useEffect(() => {
    const down = (e) => {
      if (e.key === 'k' && (e.metaKey || e.ctrlKey)) {
        e.preventDefault()
        setOpen((open) => !open)
      }
    }

    document.addEventListener('keydown', down)
    return () => document.removeEventListener('keydown', down)
  }, [])

  return (
    <Command.Dialog open={open} onOpenChange={setOpen} label="Global Command Menu">
      <Command.Input />
      <Command.List>
        <Command.Empty>No results found.</Command.Empty>

        <Command.Group heading="Letters">
          <Command.Item>a</Command.Item>
          <Command.Item>b</Command.Item>
          <Command.Separator />
          <Command.Item>c</Command.Item>
        </Command.Group>

        <Command.Item>Apple</Command.Item>
      </Command.List>
    </Command.Dialog>
  )
}

Parts and styling

All parts forward props, including ref, to an appropriate element. Each part has a specific data-attribute (starting with cmdk-) that can be used for styling.

Command [cmdk-root]

Render this to show the command menu inline, or use Dialog to render in a elevated context. Can be controlled with the value and onValueChange props.

Note

Values are always trimmed with the trim() method.

const [value, setValue] = React.useState('apple')

return (
  <Command value={value} onValueChange={setValue}>
    <Command.Input />
    <Command.List>
      <Command.Item>Orange</Command.Item>
      <Command.Item>Apple</Command.Item>
    </Command.List>
  </Command>
)

You can provide a custom filter function that is called to rank each item. Note that the value will be trimmed.

<Command
  filter={(value, search) => {
    if (value.includes(search)) return 1
    return 0
  }}
/>

A third argument, keywords, can also be provided to the filter function. Keywords act as aliases for the item value, and can also affect the rank of the item. Keywords are trimmed.

<Command
  filter={(value, search, keywords) => {
    const extendValue = value + ' ' + keywords.join(' ')
    if (extendValue.includes(search)) return 1
    return 0
  }}
/>

Or disable filtering and sorting entirely:

<Command shouldFilter={false}>
  <Command.List>
    {filteredItems.map((item) => {
      return (
        <Command.Item key={item} value={item}>
          {item}
        </Command.Item>
      )
    })}
  </Command.List>
</Command>

You can make the arrow keys wrap around the list (when you reach the end, it goes back to the first item) by setting the loop prop:

<Command loop />

Dialog [cmdk-dialog] [cmdk-overlay]

Props are forwarded to Command. Composes Radix UI's Dialog component. The overlay is always rendered. See the Radix Documentation for more information. Can be controlled with the open and onOpenChange props.

const [open, setOpen] = React.useState(false)

return (
  <Command.Dialog open={open} onOpenChange={setOpen}>
    ...
  </Command.Dialog>
)

You can provide a container prop that accepts an HTML element that is forwarded to Radix UI's Dialog Portal component to specify which element the Dialog should portal into (defaults to body). See the Radix Documentation for more information.

const containerElement = React.useRef(null)

return (
  <>
    <Command.Dialog container={containerElement.current} />
    <div ref={containerElement} />
  </>
)

Input [cmdk-input]

All props are forwarded to the underlying input element. Can be controlled with the value and onValueChange props.

const [search, setSearch] = React.useState('')

return <Command.Input value={search} onValueChange={setSearch} />

List [cmdk-list]

Contains items and groups. Animate height using the --cmdk-list-height CSS variable.

[cmdk-list] {
  min-height: 300px;
  height: var(--cmdk-list-height);
  max-height: 500px;
  transition: height 100ms ease;
}

To scroll item into view earlier near the edges of the viewport, use scroll-padding:

[cmdk-list] {
  scroll-padding-block-start: 8px;
  scroll-padding-block-end: 8px;
}

Item [cmdk-item] [data-disabled?] [data-selected?]

Item that becomes active on pointer enter. You should provide a unique value for each item, but it will be automatically inferred from the .textContent.

<Command.Item
  onSelect={(value) => console.log('Selected', value)}
  // Value is implicity "apple" because of the provided text content
>
  Apple
</Command.Item>

You can also provide a keywords prop to help with filtering. Keywords are trimmed.

<Command.Item keywords={['fruit', 'apple']}>Apple</Command.Item>

<Command.Item
  onSelect={(value) => console.log('Selected', value)}
  // Value is implicity "apple" because of the provided text content
>
  Apple
</Command.Item>

You can force an item to always render, regardless of filtering, by passing the forceMount prop.

Group [cmdk-group] [hidden?]

Groups items together with the given heading ([cmdk-group-heading]).

<Command.Group heading="Fruit">
  <Command.Item>Apple</Command.Item>
</Command.Group>

Groups will not unmount from the DOM, rather the hidden attribute is applied to hide it from view. This may be relevant in your styling.

You can force a group to always render, regardless of filtering, by passing the forceMount prop.

Separator [cmdk-separator]

Visible when the search query is empty or alwaysRender is true, hidden otherwise.

Empty [cmdk-empty]

Automatically renders when there are no results for the search query.

Loading [cmdk-loading]

You should conditionally render this with progress while loading asynchronous items.

const [loading, setLoading] = React.useState(false)

return <Command.List>{loading && <Command.Loading>Hang on…</Command.Loading>}</Command.List>

useCommandState(state => state.selectedField)

Hook that composes useSyncExternalStore. Pass a function that returns a slice of the command menu state to re-render when that slice changes. This hook is provided for advanced use cases and should not be commonly used.

A good use case would be to render a more detailed empty state, like so:

const search = useCommandState((state) => state.search)
return <Command.Empty>No results found for "{search}".</Command.Empty>

Examples

Code snippets for common use cases.

Nested items

Often selecting one item should navigate deeper, with a more refined set of items. For example selecting "Change theme…" should show new items "Dark theme" and "Light theme". We call these sets of items "pages", and they can be implemented with simple state:

const ref = React.useRef(null)
const [open, setOpen] = React.useState(false)
const [search, setSearch] = React.useState('')
const [pages, setPages] = React.useState([])
const page = pages[pages.length - 1]

return (
  <Command
    onKeyDown={(e) => {
      // Escape goes to previous page
      // Backspace goes to previous page when search is empty
      if (e.key === 'Escape' || (e.key === 'Backspace' && !search)) {
        e.preventDefault()
        setPages((pages) => pages.slice(0, -1))
      }
    }}
  >
    <Command.Input value={search} onValueChange={setSearch} />
    <Command.List>
      {!page && (
        <>
          <Command.Item onSelect={() => setPages([...pages, 'projects'])}>Search projects…</Command.Item>
          <Command.Item onSelect={() => setPages([...pages, 'teams'])}>Join a team…</Command.Item>
        </>
      )}

      {page === 'projects' && (
        <>
          <Command.Item>Project A</Command.Item>
          <Command.Item>Project B</Command.Item>
        </>
      )}

      {page === 'teams' && (
        <>
          <Command.Item>Team 1</Command.Item>
          <Command.Item>Team 2</Command.Item>
        </>
      )}
    </Command.List>
  </Command>
)

Show sub-items when searching

If your items have nested sub-items that you only want to reveal when searching, render based on the search state:

const SubItem = (props) => {
  const search = useCommandState((state) => state.search)
  if (!search) return null
  return <Command.Item {...props} />
}

return (
  <Command>
    <Command.In
