Well, that's the whole point of using the relationshipLists. If you're using a lookup column, then you're using a list for the source anyway. Or maybe I'm missing something.

Thanks for the quick answer. The columns are not necessarily defined as a lookup columns in my case. And also their definition has nothing to do with the search form (eg. if value is required). I don't think SPCascadeDropdowns fits for my use case, and I've implemented it in the meantime using JSOM.
