Expandable Sections or pages in LiveCycle, best solution

I have a form that needs tweaking.  I need to be able to add additional info for certain sections of the form if need be.  I am not sure the best way to  go about without adding a extra page that may get printed sometimes that could be blank.   I also need to allow for expandable fields that could grow as the user enters text into them allowing the entire area to display and print.
