Hiall, Unfortunately I just can''t find out how to setup a default selected value when using collection_select. My call is like so: <%= collection_select(:consultant, :lastname, @consultants, :id, :lastname, { :selected => @current_consultant.id } ) %> which is not working, I debugged so far that I know that @current_consultant.id contains the correct value. Any tips? cheers

Before I waste more time trying to figure that out, I was wondering if it''s even possible? The Rails Way says that observe_field by default will trigger changes in text fields and text areas, and on clicks for radio buttons and check boxes. So perhaps I''m using the wrong tool here?

Didn''t know what else to call this subject, sorry. Anyway this is more a general discovery question then a coding one. Is it possible (and I already know it should be) to create forms where depending on a particular choice in one select tag, one or another select tags would be presented in the form. As an example, a shopping site , where a dropdown has options of: 1-Men''s shoes
