I have a little problem.
I should have two attribute which are depend on each other.
I attached a picture about it.
Two attribute name is Customer type and Customer category.
If the user selects ‘A’ Customer type with a drop-down select, then user can only choose categories which are belong to ‘A’. And the same witch ‘B’ Customer type. If user select ‘B’ for Customer type, then user can not choose ‘apple’ for Customer category. I guess user can’t choose category till user did not chosen a type.
Could you help me how to implement this into my Customer entity? Or how to control it on the edit screen?
