The Submenus plugin adds drop-down menus to project and wiki titles that lead to subprojects or subpages. It also offers wiki macros that can be used to embed subprojects and wiki subpages as lists or tables. The submenus plugin thus offers additional options for navigating through your projects and wiki pages - in addition to the traditional breadcrumb trail.
"While the breadcrumb trail leads you back home, the submenus plugin takes you straight to the gingerbread house!"
