Hey there @jordan
Your “search input” is the first field. That’s the field that displays on the dropdown in other collections.
You can rearrange the parameters on the collection so that a different one is in the first position.
Since all of your records’ “Search input” parameters are blank, that’s why you’re seeing the blank options for the dropdown.
So simply move that one down below the tmdb_id parameter on the collections and you’ll see the tmdb_id in the dropdown. Or set whichever one you want to the first position.
