This works, but may not be exactly what you are looking for
though?
---------------------------------
<dtml-var standard_html_header>

Normal Tree<br>
<dtml-tree branches_expr="objectValues(['Folder'])">
  <dtml-var id>
</dtml-tree>

Hidden Folder Test<br>
<dtml-tree branches_expr="objectValues(['Folder'])">
  <dtml-if expr="not is_hidden"><dtml-var id></dtml-if>
</dtml-tree>

<dtml-var standard_html_footer>
---------------------------------

There may be a way to get it to work in the branches_expr???
