Class: SimpleNavigation::Renderer::List

Inherits:
Base
  • Object
show all
Defined in:
lib/simple_navigation/renderer/list.rb

Overview

Renders an ItemContainer as a

    element and its containing items as
  • 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

      containing the sub navigation inside the active
    • 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

    • 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.
