class SimpleNavigation::ItemAdapter
This class acts as an adapter to items that are not defined using the DSL in the config/navigation.rb, but directly provided inside the application. When defining the items that way, every item you provide needs to define the following methods:
-
key
-
name
-
url
and optionally
-
options
-
items
- if one of your items has a subnavigation it must respondto <tt>items</tt> providing the subnavigation.
You can also specify your items as a list of hashes. The hashes will be converted to objects automatically. The hashes representing the items obviously must have the keys :key, :name and :url and optionally the keys :options and :items.
See SimpleNavigation::ItemContainer#item for the purpose of these methods.
