I am needing this mutually exclusive such that if I select a top level option, Nth level options may not be available (and thus dissappear from selection). So, as an example for product above, if someone selected 72" rod and the titanium finish is not available for that length, it would disappear.
I would prefer if this was tied to existing products instead of the arcane attribute options currently available.
