Usage

CommandPalette is a compound component built on Base UI's Autocomplete
primitive. It provides accessible keyboard navigation and customizable
styling for command palette interfaces.

interface Item {
  id: string;
  title: string;
}

const items: Item[] = [
  { id: "1", title: "Create Project" },
  { id: "2", title: "Open Settings" },
];

export default function Example() {
  const [open, setOpen] = useState(false);
  const [search, setSearch] = useState("");

  return (
    <>
      <button onClick={() => setOpen(true)}>Open</button>
      <CommandPalette.Root
        open={open}
        onOpenChange={setOpen}
        items={items}
        value={search}
        onValueChange={setSearch}
        itemToStringValue={(item) => item.title}
        getSelectableItems={(items) => items}
      >
        <CommandPalette.Input placeholder="Search..." />
        <CommandPalette.List>
          <CommandPalette.Results>
            {(item) => (
              <CommandPalette.Item
                key={item.id}
                value={item}
                onClick={() => setOpen(false)}
              >
                {item.title}
              </CommandPalette.Item>
            )}
          </CommandPalette.Results>
          <CommandPalette.Empty>No results</CommandPalette.Empty>
        </CommandPalette.List>
      </CommandPalette.Root>
    </>
  );
}

Keyboard Navigation

Built-in keyboard navigation is provided automatically:

KeyboardShortcuts

Examples

With Grouped Items

Group related commands together with labels.

Simple Flat List

For simpler use cases, use a flat array of items without grouping.

Loading State

Show a loading spinner while fetching results.

Disabling Browser Autocomplete

Pass standard HTML input attributes like autoComplete, autoCorrect, spellCheck, and data-* to suppress browser and password manager autocomplete overlays.

ResultItem with Breadcrumbs

Use `ResultItem` for rich items with
breadcrumbs, icons, and optional text highlighting.
