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 returning
undefined method `name' for #<Array:0xb48bf628>
