Defined in:
lib/simple_navigation/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, it renders another <ul> containing the sub navigation inside the active <li> element.

If the SimpleNavigation.config.render_all_levels option is set to true, it always renders all levels of navigation (fully expanded tree).

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.
