  ComboboxItem,
  ComboboxList,
  ComboboxTrigger,
  ComboboxValue,
} from "@/components/ui/combobox"

const countries = [
  { value: "ar", label: "Argentina" },
  { value: "au", label: "Australia" },
  { value: "br", label: "Brazil" },
  { value: "ca", label: "Canada" },
  { value: "de", label: "Germany" },

  { value: "nl", label: "Netherlands" },
  { value: "uk", label: "United Kingdom" },
  { value: "us", label: "United States" },
]

export function ComboboxButtonTrigger() {
  return (
    <Combobox items={countries} defaultValue={countries[6]}>
      <ComboboxTrigger
        aria-label="Country"
        render={<Button variant="outline" />}
      >
        <ComboboxValue />
      </ComboboxTrigger>
      <ComboboxContent>
        <ComboboxInput placeholder="Search countries" />
        <ComboboxEmpty>No country found.</ComboboxEmpty>
        <ComboboxList>
          {(item: (typeof countries)[number]) => (
            <ComboboxItem key={item.value} value={item}>
              {item.label}
            </ComboboxItem>
          )}
        </ComboboxList>
      </ComboboxContent>
    </Combobox>
  )
}
