module RocketNavigation
module Renderer
# 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.
