I would like to have the same menu bar on the left side of a set of pages, but those pages will only be identified by their parent page.
(these are area all on the main menu at the top of the page).
2. Project A
3. Project B
However, on all of the pages that are nested under "Project A" I want to have a left sidebar that is visible on all pages where "Project A" is the parent or grandparent of that page.
