Hi all!
I’m excited to announce we’ve started rolling out Forms Branching!
With this new feature, you can associate follow-up questions to drop-down or multi-select answers. For example, if a user selects a specific answer in the drop-down, they automatically receive a follow up question related to that answer. You can also create more follow up questions for those answers, it’s be possible to have up to 5 branches per question.
Please find more details and screenshots in our recent announcement here:
Thanks @Francesco_Alessi for requesting this feature initially! 
We’re rolling out this update gradually, so don’t worry if you can’t access this feature just yet, it will be available to everyone within the next couple of days/weeks!
Let me know if you have any questions or feedback!
