Hello, I would like to do the following : create a new class, with a number of properties being lists. For the end-user it would be like this : select an entry in first list, depending on the value, the second list is restricted to a limited number of choices. And the same on and on with third list. Constraint : I cannot modify database and create new tables and such. Do you think this would be feasible ? I hoped, if yes, someone could just through some ideas to start with, because I'm not sure on how to proceed to have such "dynamic" lists ...
