Well, probably I`m trying in the hardest way... And I
already read the book ch3... what I want to do is to list
directories. The problem is that the document that list is
in a directory below of the directories to list.

I tryed many diferent ways, but all I could do was list some
directories, but when I tryed to list the subdirectory of
the subdirectory of...., didn`t work.

Take a look at my code:

<dtml-if "REQUEST.has_key('parametro')==1">

<dtml-call "REQUEST.set('base',_.getitem(base+'.'+parametro))">
"<dtml-var base>"

<table>
<dtml-with base>
<dtml-in objectItems>
   <td>
   <dtml-if "meta_type=='Folder'">
     <IMG SRC="../imagens/Folder_icon.gif">
     <td><a href="arvore_dtml?base=<dtml-var
base>&parametro=<dtml-var id>"><dtml-var id></a>
   <dtml-else>
     <IMG SRC="../imagens/iconImage.jpg">
     <td><dtml-var id>
   </dtml-if>
  </tr>
</dtml-in>
</dtml-with>
</table>

Thanks...
