Class SimpleNavigation::Renderer::Breadcrumbs
In: lib/simple_navigation/rendering/renderer/breadcrumbs.rb
Parent: SimpleNavigation::Renderer::Base

Renders an ItemContainer as a <div> element and its containing items as <a> elements. It only renders ‘selected’ elements.

By default, the renderer sets the item‘s key as dom_id for the rendered <a> 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. The ItemContainer‘s dom_class and dom_id are applied to the surrounding <div> element.
