Tree Menu Mod

Hi David

First you need to specify exactly when the other menu entries should disappear. Is it once you reached the maximum depth or a depth of 4 or something else?
And why does the menu entry 1.2.1.2 appear here? It is neither a parent, a sibling or a child of 1.2.1.1.1.

1.2
  1.2.1
     1.2.1.1
        1.2.1.1.1
     1.2.1.2

Also please tell me the full name of the template you use (including the path starting with design)?

Ah, out of some strange reasons I thought that 1.2.1.1.1 was selected - sorry.

Although you could use the treemnu for that you would have to do quite a ot of checking whether you want to display a certain item or not as the treemenu can be limited only in the depth, not in the width.

I think the easiest way would be to use the $module_result.path as this contains the names and urls of all parent nodes. Then you would need to fetch the siblings and the children.
So the result would be something like this (this is even a bit tested as I have done this for me a while ago):

{if is_set($module_result.node_id)}
 <ol>
 {foreach $module_result.path as $path_item}
  {if $path_item.url}
   <li><a class="parent" href={$path_item.url|ezurl()}>{$path_item.text|wash()}</a>
    <ol>
  {/if}
 {/foreach}
 
 {* now fetch the siblings and children of the current node *}
 {def $current_node = fetch('content', 'node', hash('node_id', $module_result.node_id))}
 {def $siblings = fetch('content', 'list', hash('parent_node_id', $current_node.parent_node_id,
                                                'sort_by', $current_node.parent.sort_array))}
 {foreach $siblings as $sibling}
  {* if the current node, fetch children *}
  {if $sibling.node_id|eq($current_node.node_id)}
   <li><a class="sibling" href={$sibling.url_alias|ezurl()}>{$sibling.name} </a>
   {def $children = fetch('content', 'list', hash('parent_node_id', $current_node.node_id,
                                                  'sort_by', $current_node.sort_array))}
   {if $children}
    <ol>
    {foreach $children as $child}
     <li><a class="child" href={$child.url_alias|ezurl()}>{$child.name} </a></li>
    {/foreach}
    </ol>
   {/if}
   </li>
  {else}
   <li><a class="sibling" href={$sibling.url_alias|ezurl()}>{$sibling.name} </a></li>
  {/if}
 {/foreach}
 </ol>
 
 {* we have opened count($module_result.path)|sub(1) li and ol which we need to close again *}
 {def $ol_cnt = count($module_result.path)|sub(1)}
 {for 1 to $ol_cnt as $cnt}
   </li>
  </ol>  
 {/for}
{/if}

Hope it helps

Just skip the first two iterations for where the module_result.path is looped through and remember that this changes the number of opened ol and li so you need to change the last loop as well. Not sure whether this will have the desired result but as the code is fairly easy just play with a bit to learn how it works.
