I'm recreating a form where they had several text fields on top of each other. If the form were not interactive, that would be so the user could use it to fill out longer, more detailed responses to the questions.
But since it's supposed to be interactive, I question the need for this, unless I could link them somehow, so that a user's long answer would flow from one field to the next as needed.
Is there a way to do that? Or would it work better to combine the 3 text fields into one big text field?
If the latter, is there a way to change a text field back into a text or picture box? I can't seem to find that option.
You cannot link PDF fields to each other.
Make a text field Multiline and Scrollable to allow for extra input (in Acrobat, but not in InDesign, you can also set a limit on the number of characters).
As I said elsewhere, choose Object > Interactive > Convert to Object to change a field to a regular object.
