I have the requirement to create two lists: the second one being dynamically populated with Sitecore data after the user selects a value from the first one. I tried using some Rules for WFFM but can't seem to match any with what I want to have as results.
I would like to have something like countries in the first list. After selecting a value, the second list will dynamically populate the regions depending on the country selected - if the country has regions, else a N/A single element will be added.
What is the best way and approach for doing this dependent drop lists functionality for a WFFM form (Sitecore 8.1 - webforms)?
