Menus defined with the menu editor are stored in a publication's
menu resource, an XML file stored in the publication's
folder. The menus defined in the file are made available to the template
MenuItem Java objects, which can be
accessed using the
menu tag library. This tag library
is supplied as part of the Menu Editor plugin.
The menus created using the menu tag library can potentially contain
large amounts of dynamic content, in which case rendering them might
become a time-consuming process. It such cases it may be a good idea to
<util:cache> JSP tag to improve menu
Caching the menus may have a significant effect, since menus are usually identical for all page views in a section; sometimes even for all page views.
