{#
Displays a tree of organzations

NB This template can be slow because it is recursive and uses link_for. At
DGU we speeded up display of the tree 10 times (necessary as we have 1000 
organizations) by replacing this template with a recursive code routine:

orgs    - List of organizations

Example:

  {% snippet 'group/snippets/group_tree.html', top_nodes=h.get_action('group_tree', {'type': 'group'}) %}

#}
<ul>
  {% for node in top_nodes recursive %}
    <li id="node_{{ node.name }}">
      {% if node.highlighted %}
        <strong>
      {% endif %}
      {% link_for node.title, controller='group', action='read', id=node.name %}
      {% if node.highlighted %}
        </strong>
      {% endif %}

      {% if node.children %}
        <ul> {{ loop(node.children) }} </ul>
      {% endif %}
    </li>
  {% endfor %}
</ul>
