Defined in:
lib/simple_navigation/rendering/renderer/list.rb

Overview

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 autogenerate_item_ids 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.
