Hi, I've faced a similar problem: A main menu with top-level pages and an accordion-style sidebar menu. My solution: 1. In tabs.jsp, I always render both menus (ul/li structures) 2. In layout pages, I have two instances of the "navigation" region, using distinct "regionID" values. 3. In the theme CSS files, I show/hide the unwanted menu for each case, using the different regionIDs. As an optimization, you can save the rendered markup on step 1 at session level when called from the first occurence of the nav region and use this cached data to render subsequent calls.
