.render_menu2(aOptions = nil) ⇒ Object

render_menu(), or more precisely menu_items() doesn’t seem to work well for rendering a top menu when you want the ancestor item of the current page highlighted. The problem is that it compares each menu item with the current page, when the current page may be several levels deep under one of the menu items.

Fortunately the :page option allows the current page to be given, so the correct output can be produced if we manipulate this option.

This does the trick :
