I need help ASAP - Showing fields based on dropdown selection

I WANT TO DUPLICATE THIS SAME FEATURE SOMEONE ELSE HAS 

https://form.jotform.com/200728448739162 

ITS A DROP DOWN MENU BUT DEPENDING ON WHICH OPTION I SELECT IT GIVES ME A DIFFERENT SET OF QUESTION. 

HOW CAN I SET SOMETHING SIMILAR TO THIS? 

First, you will need to add the form fields you need, and then configure the 'Show Field' conditions.
