Now I created third content type name it as details in that I need two drop down one is list of tour I have added and another one is list of location I have inserted.

  • Hello. Links may be helpful, but assume they are down, for any reason. Do you think your answer would still be useful?.. It would be better to provide excerpts, quotes or instructions based on linked content, so your answer would have a value on it's own.
