This may be a stretch, but I have a site that has a large number of pages, and i've given the pages categories (with a plugin that let me add categories to pages). I now want to create a sidebar menu that pulls all the pages from the category of the page you're on.
So if you're on a page that is categorized under 'Beaches', i want it to list all other pages under that category.
If that makes sense.
How can I do that?
