I need to have, say for example, 15 drop downs, that are pulling data and allowing users to specify folder paths in the spreadsheet.

So as you can imagine, the drop downs need to change accordingly to allow them to go down path routes (using drop-downs left to right), that I am currently specifying through named ranges.

I really need whatever approach I take to accommodate for there being up to hundreds of different categories, be that top level, sub level, sub-sub level, sub-sub-sub level, etc. etc. I just wish there was a basic way to do this for selections that will need loads of different layers...

I would really appreciate some help with this,
Cheers,
Billy
