Mobile scrolling problem

Hi all, I am really hoping some kind person on here can help. I have a web page with a header containg menus and other stuff and a footer with various inks, in the body I have a Babylon.js 3d games machine, what I want to do is have an icon on each panel eg. front, left side and rifgt side so that when a user clicks the icon a Modal page drops down and the user can select an image for the panel, the only problem is on a mobile when you scroll down to bring the games machine into view you can’t then scroll up or down to get back to the menus in the header section, is there a way of doing this without resorting to a overlaying div, hope this makes sense. any help I would truly be thankful for


I’m not sure it is relate4d to bjs right? seems more fitted to stackoverflow I guess
