@Rekl0w Ok thanks for letting me know

@greatstefan yes it is the same.

Yes, the problem was because I had a "CommandGroup" component directly in "Command" and I had to wrap the "CommandGroup" in another component called "CommandList" and now works. So:

<CommandList>
  <CommandGroup>
    {options.map((option) => (
      <CommandItem
        key={option.value}
        onSelect={() => {
          onChange(option.value === value ? "" : option.value)
          setOpen(false)
        }}
      >
        <Check
          className={cn(
            "mr-2 h-4 w-4",
            value === option.value ? "opacity-100" : "opacity-0"
          )}
        />
        {option.label}
      </CommandItem>
    ))}
  </CommandGroup>
</CommandList>
