This dependent behavior is not a feature of the current version of the plugin, but we are looking at it as a new feature for V3. Some users have achieved this using custom javascript, created by their own coders/freelancers. The js monitors the onchange of a field and then as the value changes, so it changes the CSS on each field to hide/reveal as required.

I am sorry, but this is not an advertised feature of our plugin at this time. It may become part of the plugin in the future, but I have no information on that as of yet.

As I said, it should be possible to hire a freelancer coder to do this, but I do not have any code snippets that might help you.

It is possible to get the terms in any field to filter based on the choices made in another field (where not applicable terms disappear), but not to actually hide the field itself. Based on what you say, some fields would have no terms in them after you make a choice, and so the javascript you write could look for the empty fields and hide them.
