right, I understand that. You can use multiple scrolling regions.
Scrolling Region 1 Header
/***********************/
/ /
/ Scrolling Region1 /
/ /
/***********************/
Scrolling Region 2 Header
/***********************/
/ /
/ Scrolling Region2 /
/ /
/***********************/
ect...
You could also create some dummy fields that could be used to control the visibility of the other fields with a button. You have section1 and dummy1. Set rules inside section1 so that its hidden if dummy1 = false. Make a button that toggles the value of dummy1. If dummy1 == false, then set dummy1 = true. If dummy1 == true, then set dummy1 = false. With a click of the button you could quickly control the visibility of the section.
A third option would be a repeating table. I personally dont like repeating tables, but that may be what you might need.
