Overview

Renders an ItemContainer as a <div> element and its containing items as <a> elements. It adds the ‘selected’ class to the <a> element that is currently active.

The Links renderer cannot be used to render nested navigations. If you would like it to use with nested navigations, you have to render each level separately.

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.
