I am not quite sure what you are trying to accomplish...

(1) create a form with a drop-down list of folders that are contained within
the current folder:

<form>
<select name="xxx">
<dtml-in "objectValues('Folder')">
  <option value="<dtml-var id>"> <dtml-var id>
</dtml-in>
</select>
</form>

(2) create a property field on the current folder which contains a list of
the subfolders contained within the folder

<dtml-call "REQUEST.set('flist', [])">
<dtml-in "objectValues('Folder')">
  <dtml-call "flist.append(id)">
</dtml-in>
<dtml-call "manage_addProperty('ThemeFolder', flist, 'lines')">

(3) display a drop-down list which contains the contents of a property field
of a folder (the property field has previously been created and contains a
list of the subfolders - see item 2 above)

<form>
<select name="xxx">
<dtml-in "getProperty('ThemeFolder')">
  <option value="<dtml-var sequence-item>"> <dtml-var sequence-item>
</dtml-in>
</select>
</form>

(4) something else?
