check if the key is the first key if yes mark checked otherwise do not mark

@foreach($property_get->getPhotoGroupList() as $key => $grupo)
    <input id="tab{{ $key }}" type="radio" name="tabs" {{  @if($key == 0) ? 'checked'  :  ' ' }}>
    <label class="band band-two lastWord" for="tab{{ $key }}">{{ $grupo->getName() }}</label>
@endforeach
