Hello,

	I have a section of my site that builds up the navigation list. On the 
bottom of this email you can find a sample array, the smarty code and 
the output.

	The array has a variable called position. The default is for position 
not to be set. As it stands the foreach loop outputs the list in the 
order in which it receives it (which is the order in which they were 
put into the db).

	However I'd like for smarty to output the list in the order in which 
it receives it _except_ when the position is explicitly set. For 
example a user could add a Home link and set it to position=1.

  	I'm not sure how exactly to do this and would appreciate any 
suggestion you may have.

Array
(
     [Preferences] => Array
         (
             [id] => 2
             [name] => Preferences
             [type] => title
             [value] =>
	   [position] =>
             [children] => Array
                 (
                     [Personal Details] => Array
                         (
                             [id] => 1
                             [name] => Personal Details
                             [type] => preferences
                             [value] => personal_details/
			[position] =>
                             [children] =>
                         )

                 )

         )...

	The smarty foreach that builds the list looks like so:

    <ul>
     {foreach name=category from=$userNavi key=catkey item=category}
         {if $category.type eq "title"}
         <li class="category">{$category.name}</li>
         {else}
         <li class="category"><a 
href="{$category.value}">{$category.name}</a></li>
         {/if}
         {foreach name=subcategories from=$category.children 
key=subcatkey item=subcategory}
             <li class="subcategory"><a 
href="{$subcategory.value}">{$subcategory.name}</a></li>
         {/foreach}
     {/foreach}
     </ul>

	The output is then:

<li class="category">Preferences</li>
<li class="subcategory"><a href="personal_details/">Personal 
Details</a></li>
