Rails - Jan 2013 - Add data in between Simple Form association members

Hey there,

I am trying to use Simple Form''s association to list a bunch of radio 
buttons like so: 

  <%= simple_form_for(@applicant) do |f| %>    
    <%= f.association :track, :as => :radio_buttons %>
  <% end %>

Assuming each track has many courses, how can I take every track from that 
association and loop over its courses to display them below the radio 
button? After all applicants need to know what each track has. 

Best,
