Creating scrollable frames in DPS is easy. Just create a content frame and a container frame, paste the content frame into the container frame, and then use the Overlays panel to specify scrollable frame settings for the container frame. (If you’re confused, see the help article about scrollable frames, and then come back.)
But what if you know the content isn’t final and you’re going to edit the scrollable frame content later? And what if your scrollable frame content includes a bunch of buttons and overlays that are hidden from view?
