I am trying to create menus on the sidebar that populate themselves based on a custom field entry. Ultimately, I want to create menus that look like this:
(look at the left side of the page)
What I want to do is to set a custom field, like, say,
year, where all of the pages that contain that custom field value are output in a sidebar widget. I can't seem to find a plugin or anything that will do such a thing, and so I don't know if I'm missing something or not, but it certainly seems like something that the system should be capable of doing.
Any ideas? This affects only pages - no posts or custom posts.
