Hierarchical menus can be defined when the UI Top Level Page has a template selected for ModulePageTemplate that supports menu generation.
The Standard.cst menu template is located in c:\program files\flynet\Viewer\Studio\ProjTemplates\WebMenus. It will generate a simple menu with as many levels as you care to define in the Tasks tree view.

While the Enhanced UI Templates include a default, multi-level DHTML menu and included CSS settings in the CSS file template, any menu solution compatible with an ASP.NET delivery can be generated with the addition of custom templates into the WebMenus template folder.
