The formtastic gem might be able to help you.
https://github.com/justinfrench/formtastic

It makes writing forms a lot easier and has helpers for writing groups
of buttons and stuff.  Here's an example from the readme on github...
 f.input :authors, :as => :check_boxes, :collection => User.find(:all,
:order => "last_name ASC")
  f.input :authors, :as => :check_boxes, :collection =>
current_user.company.users.active
  f.input :authors, :as => :check_boxes, :collection => [@justin, @kate]
  f.input :authors, :as => :check_boxes, :collection => ["Justin",
"Kate", "Amelia", "Gus", "Meg"]
  f.input :author,  :as => :select,      :collection =>
Author.find(:all)
  f.input :author,  :as => :select,      :collection => { @justin.name
=> @justin.id, @kate.name => @kate.id }
  f.input :author,  :as => :select,      :collection => ["Justin",
"Kate", "Amelia", "Gus", "Meg"]
  f.input :author,  :as => :radio,       :collection => User.find(:all)
  f.input :author,  :as => :radio,       :collection => [@justin, @kate]
  f.input :author,  :as => :radio,       :collection => { @justin.name
=> @justin.id, @kate.name => @kate.id }
  f.input :author,  :as => :radio,       :collection => ["Justin",
"Kate", "Amelia", "Gus", "Meg"]
  f.input :admin,   :as => :radio,       :collection => ["Yes!", "No"]
