Kindly see attached files and descriptions of features being asked:
-Disable certain roles/users from dragging-and-dropping content controls OUTSIDE of the set content placeholder. As of the current set-up, users can perpetually drag-and-drop unlimited amounts of controls anywhere in the page. (Note: setup utilizes nested master pages.
-Disable over-nesting of layout controls and limit up to two nestings only. Our concern is that user might be too negligent about adding excessive layout controls and then in turn cause mayhem in the layout of the page.
