You could have a look at acts_as_tree to build up a hierarchy of options using a single model http://wiki.rubyonrails.org/rails/pages/ActsAsTree So you could have first options: A and B and as children of A have: C and D and as children of B have: E and F You can scale this to as many levels as you like.
