<p class="descriptiveText">{i18n}Many "lookup" fields make sense in a hierachy:
countries are part of continents and sub-continents, school classes are part of grades
and programs, Powerbooks are Apple Macs, while Thinkpads are made by Lenovo.  This 
page will allow you to arrange the lookups in the field in a hierachy.  All changes
are immediately stored, so when you are done simply navigate back to the field menu.{/i18n}</p>


<form action="{$smarty.server.PHP_SELF}" method="POST">
<fieldset>
  <legend>{i18n arg_category="$category_name"}Add New Subcategory to <strong>#category#</strong>{/i18n}</legend>
  
  <p class="descriptiveText">{i18n}In order to organise the options into a "tree", you 
  need to add subcategories at each level.  The "top" level is called the root, and 
  holds all the toplevel items.  "Root" will not be shown to the final user, but 
  provides a single "parent" to the toplevel items.{/i18n}</p>
  
  <p class="descriptiveText">{i18n}As an example, if you are creating a tree of the
  countries in the world, the actual countries would be <strong>keywords</strong> 
  (e.g. South Africa, England, Pakistan, India, etc.).  The highest group of categories 
  would be continents &mdash; e.g. Africa, Europe, Asia, The Americas &mdash; followed by 
  subcategories that contain actual countries &mdash; e.g. Western Europe, Sub-Saharan Africa, 
  Australasia.{/i18n}</p>

<p class="descriptiveText">{i18n}Keywords which are directly below the 
  <strong>Root</strong> are considered "free" &mdash; they are not attached to 
  a subcategory.  Only free keywords can be associated with a subcategory.  To

  Deleting a subcategory will automatically unlink all keywords below it (including
