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 || e.ctrlKey)) {
e.preventDefault()
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>

## Changelog
### 2024-10-25 Classes for icons
Added `gap-2 [&_svg]:pointer-events-none [&_svg]:size-4 [&_svg]:shrink-0` to the `<CommandItem />` to automatically style icon inside.
Add the following classes to the `cva` call in your `command.tsx` file.
```tsx showLineNumbers title="command.tsx"
const CommandItem = React.forwardRef<
React.ElementRef<typeof CommandPrimitive.Item>,
React.ComponentPropsWithoutRef<typeof CommandPrimitive.Item>
>(({ className, ...props }, ref) => (
<CommandPrimitive.Item
ref={ref}
className={cn(
"... gap-2 [&_svg]:pointer-events-none [&_svg]:size-4 [&_svg]:shrink-0",
className
)}
{...props}
/>
))
```
