Hello. I'm making a scrolling web page design on InDesign. This is just for the appearance and layout, it is not becoming a actual website. Is it possible to make a interactive pdf have a part that always stays on top when scrolling? like this website (or many websites) : http://aboutmarco.com/ or/ and is it possible to make a drop down file for the menu like this?
