JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I understand that you want to change the options listed on a dropdown menu based on another question. I believe that you are looking for our widget Dynamic Dropdowns.
You may also have separate dropdown boxes to show/hide by setting up some conditions. Please take a look at the demo below if that works for you.
You may clone this JotForm to your account to see how the conditions are set.
Hope this information helps! Let us know if you need any further assistance. We will be happy to help.
