All the menu items work on an emulated simple Android 2.2 on your site. Library and Resource menus slide in smoothly. Presentation is switched to the Smartphone XHTML using the mobile_pda template.
I like the way the submenu pop-up or slide-in on your site - in our production environment - despite existing submenus - the complete page reloads. Suspect a difference in the default main menu config, or its lead to the fact we have real content on the root level of the submenus.
