[Zope] dtml-tree items filtering

[Laurie Nason]

Hi Dan,

When you call the dtml-tree method, you need to provide a
branches_expr=some_method - see
http://www.zope.org/Members/anthony/tree-coding-tricks or search the
zope.org site for dtml-tree for other how-to's. This method should only
return the objects you wish to see in the tree - so it does the filtering
for you.

Hi,

i'm trying to solve this thing: i'm building a sitemap. i have folders, that
i
want to show, and want to hide the others. to differentaite them, i leave
the
title string empty for those folders i need to hide.

i used:

<dtml-tree sort=title>
  <dtml-if "id != 'acl_users'">
     <dtml-if "title!=''">
       <A HREF="&dtml-absolute_url;" target=right>
       <IMG border=0 SRC="<dtml-var icon>"><dtml-var title></A>
     </dtml-if>
  </dtml-if>
</dtml-tree>

but having a folder with no title and a subfolder in it, the above
gives me the expand-plus-sign in the tree (but show no icon) for that
folder.

can someone help?

regards
-dm
