Retrieving Levels Optimally

[Eyrrkr]

All:

I'm trying to figure out how to optimally retrieve specific levels in a tree structure because I am building a navigation and although the root levels are the main headings, there are possibilities for other subheadings within those main headings (i.e. level 2 could be another bold subheading with level 3 as its children).  I am currently operating under the assumption that these depths could be flexible.

Below is what I currently have and I know it works although I think this is actually going in the opposite direction of what django-mptt is trying to achieve (cut down on database queries):

<ul class="root">

    {% recursetree object_list %}

        <li>

            {{ node.name }}

            {% for x in node.get_children %}

              <ul>

                {{ x.name }}

                {% if x.get_descendants %}

                  {% for y in x.get_descendants %}

                    <ul>

                      {{ y.name }}

                    </ul>

                  {% endfor %}

                {% endif %}

              </ul>

            {% endfor %}

        </li>

    {% endrecursetree %}

  </ul>

Thank you in advance for any help you can provide!
