Hello Zopisti, I hope you'll tolerate another question on navigation trees. Actually, it's related to the ZBook tutorial at ZDP. In the example, the tree is constructed within a <span class="tree"> tag. When displayed, the page renders with the tree in the prescribed style just as it should. However, when I implement the same tree syntax and the same style settings, my navigation tree displays "normal" fonts. I know my style settings are OK because I tested the <span class="tree"> tag elsewhere successfully. <SPAN CLASS="tree"> <!--#tree particle branches_expr="objectValues(['Folder', 'DTML Document'])" 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 "particle.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> Is there something about styles and DTML I'm missing here? This is really puzzling. Everything looks so right. -Tim -- wilson@chem.umn.edu
