Doing it this way seems to return an array of arrays where the 0 index is the index and the 1 index is the list of items in that group...try doing something like this:
<h2>Categories</h2>
<% @categories.group_by(&:parent_
id).each do |parent_id, categories| %> <%= <h3>parent_id</h3> %>
<% categories.each do |category| %>
<%= category.name %><br/>
<% end %>
<% end %>

This code results in ActionController returningundefined method `name' for #<Array:0xb48bf628>
