class RocketNavigation::Renderer::BreadcrumbsOnRails
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_attributes are applied to the surrounding <div> element.
