Could somebody give the tips, for the right transactions and also the steps in order to create the multilevel categorization? I have to "model" it in 4 levels, like this:
Level 1 - First dropdown
Dependending on the dropdown choice of the level 1, the second level appears:
Level 2 for Cat 1 - Second dropdown
Level 3 for Cat 1.1 - Third dropdown
and so on...
How do I do to create all this stuff? What are the transactions?
