I have a drill-down question that is from a csv file with 3 columns, where the last column is unique. Basically this is just a way to help someone find a specific category. e.g. Job Industry -> Job Group -> Job Title
To make it easier, I would like a user to be able to first just try to search for their final answer, (e.g. Job Title). However, I want to make sure the previous categories are correct (industry + group).
I have found that I can use the Select2 for searching the drill-down, but I can only get it working in order (i.e. they search first group, then it lets them search second group). So naturally I can make a single list to search of just the last category. However, I would then want to take that value and pipe -- or some other thing (this is what I am asking for advice/help on) -- right below their search and autofill the 3 groups so the user can verify that the larger categories are the ones they thought/selected.

For example, they select 'Teacher', but the exact match version of 'Teacher' is for job group 'K-12'. So they realize this and then manually change the second category in the drill-down to be 'University', and then the correct job 'Professor'.
Thanks for any help
