Field dependent options

Is it possible (invent table) to make the options available in one field dependent on another ?

e.g.

If Cost group = “A” then Stock model group can be A, B or C

If Cost group = “B” then Stock model group can be A, D or E

etc

Yes. You can override the lookup,validate methods of the fields depending on the requirement.

But before that you should have mapping of the explained example.
