I work at a university in Japan that is recruiting new students from other countries, yet expects them to fill out a form that is completely in Japanese. As the sole English-speaker, I want to make filling out the form as easy as possible. There are two fields where prospective students must choose a (1) "Desired School" and a (2) "Desired Department." If a prospective student wants to study in a certain school, they must choose a specific department within that school.
Hope you are doing well and sorry for the trouble. As described you want to connect two dropdown list using forms in Acrobat DC.
Hope this information will help
Your best bet in this case is to hire a developer that can help you with this project.
I used to be a teacher for this school. Whenever I asked for supplies for my classroom, they suggested I go to Japan's version of the Dollar Store. So I want to learn and become an in-house developer.
Do you have any suggestions on where to start?
Thank you so much for responding.
++In addition to all the great suggestions,
You need to use 'setItems()' to populate second dropdown field.
This is basic script how to do it ( there is plenty of those on this forum if you look for it)
you adapt script to your needs, it's used as 'Validation' of first dropdown field:
if(event.value == "A")
else if(event.value == "B")
