    # Renders an ItemContainer as a <ul> element and its containing items as <li> elements.
    # It adds the 'selected' class to li element AND the link inside the li element that is currently active.
    #
    # If the sub navigation should be included (based on the level and expand_all options), it renders another <ul> containing the sub navigation inside the active <li> element.
    #
    # By default, the renderer sets the item's key as dom_id for the rendered <li> element unless the config option <tt>autogenerate_item_ids</tt> is set to false.
    # The id can also be explicitely specified by setting the id in the html-options of the 'item' method in the config/navigation.rb file.
