I'm not certain it would work but if you want to give it a try, just select all the text in a section of your document you wish to hide, then click Insert -> Bookmark and give it an appropriate name (i.e. Bob1 or John1). Then you could write a macro for collapsing/expanding the bookmarked area, something like this:
Where strSection is the name of the bookmark for the area you wish to expand or collapse. As for how to activate this macro, you could put a command button at each expand/collapse point that calls the ToggleSection macro (passing the name of the bookmark for that section), or you could do a Ctrl+F9 and in the {} that appear, write "MACROBUTTON ToggleSection("BookmarkName") Toggle" (without quotes). Then you press Alt+F9 to confirm and set up the button (which will just say "Toggle" and will expand/collapse the section whenever it is double clicked). You could, of coarse change the last word in the curly brackets to say anything (it doesn't have to be "Toggle").
