How would I go about displaying a node so that the node's grandchildren are displayed in addition to its children?

For example, I want a page that looks like:

http://stuff.belvederedesign.net/Example1.png

Rather than:

http://stuff.belvederedesign.net/Example2.png

or,

http://stuff.belvederedesign.net/Example3.png

Where 'Food I Like' is the parent; 'Fruit', 'Vegetables', and 'Sweets' are the children; and the bullets are the grandchildren. (I really don't care how the tree looks, I just care that the final output works, and is updated dynamically.)

I know that I can do this by 'not showing contents', and linking the contents manually in the description field, but this solution is less than optimal.

Would I do this in templates, or elsewhere? Any suggestions?

Hi David

Just change the full view template for the folder and for each child add an additional fetch for the children of this child.

Very basic template:

{* $node contains the node of the folder you are currently viewing *}
{* display name and description *}

<h1>{$node.data_map.name.content|wash()}</h1>

{if $node.data_map.short_description.content.is_empty|not}
 <div class="attribute-short">
  {attribute_view_gui attribute=$node.data_map.short_description}
 </div>
 {/if}
{if $node.data_map.description.content.is_empty|not}
 <div class="attribute-long">
  {attribute_view_gui attribute=$node.data_map.description}
 </div>
{/if}

{* fetch the direct children *}
{def $children = fetch('content', 'list', hash('parent_node_id', $node.node_id,
                                                            'sort_by', $node.sort_array))}
{if $children}
<ul>
 {foreach $children as $child}
 <li><a href={$child.url_alias|ezurl()}>{$child.name|wash}</a>
 {* now fetch the children of this child *}
 {def $grandchildren =  fetch('content', 'list', hash('parent_node_id', $child.node_id,
                                                                      'sort_by', $child.sort_array))}
 {if $grandchildren}
 <ul>
  {foreach $grandchildren as $grandchild}
   <li><a href={$grandchild.url_alias|ezurl()}>{$grandchild.name|wash} </a></li>
  {/foreach}
 </ul>
 {/if}
 {undef $grandchildren}
</li>
 {/foreach}
</ul>
{/if}
