I am trying to create a menu for navigation that starts out as Group1 Group2 Group3 Group4 and when you click on one of the groups it brings up one of the model tables you can navigate to. Group1 Group2 |== Model1 |== Model2 |== Model3 Group3 Group4 This is created with two helper methods and the partial \_menu.rhtml. I was wondering how to start to migrate this to ajax. I tried creating an rjs file but I don t understand the structure and how it is called in the context of rails. If anyone could help me I would really appreciate it. White W. ---

I have gotten a little further, I now have the rjs script executing . . . but the problem now is that I have many controllers and I want the action to call the function in application.rb, but it seems that it can’t find it if it is in the application controller. Is there a way around this somehow? \<%= link\_to\_remote( mg.group\_name, :update =\> “menu”, :url =\> {:action =\> [:menu]}) unless ms.first.nil? %\> other wise this works as I expect it. Any help is appreciated. White W. ---
