Wordpress.org has a top-level menu (Home, Showcase, Extend etc.). If you click on certain of these, such as Extend, you're taken to a site that has a sidebar with a submenu that shows the children of the Extend-page. If you click one of these, it keeps displaying the children of the Extend page, marks the one you clicked as active, and shows you its children.
I don't know if this is solved using subpages, but does anyone know of a way to solve this using pages and subpages in Wordpress?
I have a top-menu that shows only the top-level pages, but I can't figure out how to make a submenu to show what I've described.
Thanks in advance for all your help.
