This plugin allows you to assign WordPress navigation menus to the secondary navigation menu within the Genesis Theme Framework on a per post, per page, or per tag/category archive basis. The per post, page, category or tag setting overrides whatever menu setting you have in your Genesis Theme setting. It does require that you have your Secondary Navigation enabled in your Genesis Theme Settings.
