Can we make a fillable pdf form that expands based on what is keyed into it?
Not a regular PDF form, no. This is only a feature of PDF forms created using something called Adobe LiveCycle Designer, now known as AEM forms.
Thanks for letting me know. Does Live Cycle do everything Acrobat Pro DC does and is it a lot more expensive? Thanks for the info!!
No, not everything. It can do a lot, and it can do some things that Acrobat can't, but you have to purchase it separately. Also, be aware that any such PDF file will not work anywhere else outside of Adobe applications.
