First off, you'd be better off actually setting up some real associations. Such as: class Page < ActiveRecord::Base belongs_to :parent, :class_name => 'Page' has_many :sub_pages, :class_name => 'Page', :foreign_key => 'parent_id', :order => 'position' named_scope :main_pages, :conditions => 'pages.parent_id IS NULL', :order => 'pages.position', :include => :sub_pages end The controller code basically disappears; you can stash the results of Page.main_pages in an instance variable if you're hell-bent on avoiding model calls in the view. Here's a cleaned-up version of the view code: http://gist.github.com/264005 > > The only problem with the code above is that it only displays one > sub-menu for each parent menu item.

You didn't mention if the actual source from your original view includes all the elements; I'd hazard that the CSS for the menus might be dropping them all in a stack, which would produce the "only show the last one" behavior you've described.
