[Zope] help urgently needed...

[Jens Vagelpohl]

hi michel,

thanks a bundle for answering. here is the complete "help_menu" DTML method
which implements the tree:

<SPAN CLASS="tree">
<!--#tree help branches_expr="objectValues(['Folder', 'DTML Document'])"
nowrap=1 sort=id-->
<!--#if expr="meta_type == 'Folder'"-->
<!--#if tree-item-expanded--><IMG SRC="<!--#var
SCRIPT_NAME-->/HelpSys/hs_obook" ALIGN="TOP" BORDER="0" width=16 height=16>
<!--#else--><IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_cbook" ALIGN="TOP"
BORDER="0" width=16 height=16><!--#/if-->
<!--#var title_or_id-->
<!--#else-->
<IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_dnode" ALIGN="TOP" BORDER="0"
width=16 height=16>
<A HREF="<!--#var "help.absolute_url()"-->/<!--#var tree-item-url-->?<!--#if
tree-s-->tree-s=<!--#var tree-s--><!--#/if-->
<!--#if tree-e-->&tree-e=<!--#var tree-e--><!--#/if--><!--#if
tree-c-->&tree-c=<!--#var tree-c--><!--#/if-->">
<!--#var title_or_id--></a><!--#/if-->
 <!--#/tree-->
</SPAN>

if it is indeed some netscape error i am surprised no one else has mentioned
it. most people on the list seem to be using it.
