Can you have form field conditions in Adobe Acrobat / Adobe Sign?

Hi guys,

I'm a graphic designer, and my employer wants me to create a form in Acrobat but with conditions. 

This form is to be an an multipurpose invitation for three different kinds of events:  a forum, symposium, or luncheon.  They want to be able to first choose the type of event from a dropdown, but only have certain choices of topics populate depending upon what kind of event they've selected.  This seems like an if/then logic function to me.  If it's a Forum, then they can have Topic A, Topic X, Topic H.  If it's a Luncheon, they can choose Topic Y, Topic N, or Topic L.  If a Symposium, then Topic B, Topic W, and Topic K appear.  They only want specific topics to appear when the first condition is met, not show all 9 topics at once in the dropdown menu.

I also don't see any means of adding form field conditions using Acrobat's native Fill and Sign function.  There's nothing like this under Properties, either. I searched, and saw this is possible using Adobe Sign.  I found this tutorial:  Setting form field show/hide conditions

I have followed the tutorial to the letter, but I see no "Conditions" menu when I go to Edit.  I have every other menu except "Conditions."  At the top of that tutorial, it states, "Conditional field values are available with the business and enterprise service plans."  My company has a Pro plan. 

Am I to assume that we will never have a "Condition" menu unless we switch to a business or enterprise plan?  If so, then, is it possible to program these same if/then logic functions using JavaScript?

If I am unable to set form field conditions without learning Javascript, then my solution would be to create 3 different PDFs for them to have three different sets of choices, and never the twain shall meet.  Suggestions welcomed!
