I need to create three checkbox sets that are relational. The goal is to list individuals as being part of a primary list set, with a second level list set and third level list set that changes based on what is selected in the primary list set.
Say, I have three checkbox fields, 1 2 and 3. I need to check something in one and have the value list update in field 2, check something in 2 and it changes in 3.
I was trying to set this up using a "categories" table with recursion, but haven't been successful. Can someone recommend some tips to wrap my head around this?
I have attached my sandboxing file.
