I made a form that has expandable fields and other interactive elements but this seems to be only viewable in Acrobat Pro. Is it possible to view this type of pdf from Reader or maybe a browser?

I am making a Letter-sized form with expandable field and I want the form to flow text/objects to the next page. is this possible?  pls help.

‌I usually put a label on top of a rectangle box, but seems to not work when inside a subform. So i figured why not color the label box itself? Is this possible?
