Creating dependencies between fields in content type creation form I have two fields in my content type that I'd like to have depend on each other. The two fields are category (the dependee, a field list) and icon (the dependent field and also a taxonomy term field). They are both select lists. I want the dependent field (icon) to not be available to authors creating records in the admin interface. It should just automatically select the correct term based on the category selection above it.

I looked into 'Conditional Fields' but I'm not certain it does what I'm looking for. 

Any suggestions?
If you are looking out to do this through code, you can use hook_form_alter to hide the dependent field and hook_node_presave to set the value for dependent field.
