To collapse or "hide" the left or right sidebar on certain pages, all you need to do is make sure that no modules are assigned to that particular menu link (page). The easiest way to do this, is go to your modules manager and choose the module position filter drop down (top right) and select the module position to filter by. All that this is doing is setting the modules page to only show all modules that are assigned to the "left" (or right) module postion. For example, if you wanted not have the sidebar shown on the wrapper page, as you wanted to utilize the full width of the template, you would make sure that all modules assigned to the left + right position were set NOT to display on the wrapper menu link. This can be done by opening each of the published modules that are assigned to that position and checking that the page/menu link is deselected in the " Pages / Items" Menu Item box (right hand side of the module options).
