to build a navigation li : <div class="nav"> <ul> <% main_nav :user, :class => "first" do %> <%= link_to 'Users', users_path %> <% end %> <% main_nav :scene do %> <%= link_to 'Scenes', scenes_path %> <% end %> </ul> </div> to build a sub nav: <div class="secondary-navigation"> <ul> <% sec_nav :new, :class => "first" do %><%= link_to "tasks", user_tasks_path(current_user) %><% end %> <% sec_nav :strategy do %><%= link_to "messages", user_messages_path(current_user) %><% end %> </ul> <div class="clear"></div> </div> when user view pages correspoding to actions in users controller, we'd like the tab "User" highlight, to accomplish this: class UsersController < ApplicationController main_nav_highlight :users # bla bla bla ... end also if you need to highlight the sub nav, call "sec_nav_highlight :something" in your controller

-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
