The menu class documentation - and the provided example - do not seem to show any way for me to build a navigation menu with more than 1 level of navigation.
What do I do if I want to build an 'app-style' menu - like 'File' or 'Edit' - which will include sub-menus? Is there a way to create this automagically with Agile Toolkit, or is this something that would have to be coded by hand with html templates, css files, etc.?
