To show the command menu in a dialog, use the `<CommandDialog />` component.
```tsx
export function CommandMenu() {
const [open, setOpen] = React.useState(false)
React.useEffect(() => {
const down = (e: KeyboardEvent) => {
if (e.key === "k" && e.metaKey) {
setOpen((open) => !open)
}
}
document.addEventListener("keydown", down)
return () => document.removeEventListener("keydown", down)
}, [])
return (
<CommandDialog open={open} onOpenChange={setOpen}>
<CommandInput placeholder="Type a command or search..." />
<CommandList>
<CommandEmpty>No results found.</CommandEmpty>
<CommandGroup heading="Suggestions">
<CommandItem>Calendar</CommandItem>
<CommandItem>Search Emoji</CommandItem>
<CommandItem>Calculator</CommandItem>
</CommandGroup>
</CommandList>
</CommandDialog>
)
}
```
