I am a new user of zope (this is my 4th day). I am building a web-site for the faculty governance structure of my university. I have an overall top folder, faculty governance, three sub folders, senate, executive committee, and standing committees (which contains 10 committee folders). Each folder (senate, exec comm, and the 10 standing committees) contains subfolders for agendas, minutes, and membership. Each folder contains an index_html that refers to the standard_html_header. The standard_html_header is in the top folder and is set up as a table with the first column a sidebar, standard_choices, consisting of <p>Navigational Guide </p> <A HREF= "<!--#with "PARENTS[-1].facultygov"--> <!--#var absolute_url--> <!--#/with--> ">Faculty Governance</A> <!--#tree expr="PARENTS[-1].facultygov" branches_expr="objectValues('Folder')"--> <A HREF="<!--#var absolute_url-->"><!--#var title--></A> <!--#/tree--> What baffles me is that if I navigate from the constructed tree in the sidebar (using the + marks to open the tree to display the subfolder of interest) and make a selection by clicking on a subfolder, the opened tree sometimes collapses back to a closed tree with just the three top level choices showing and sometimes stays open, showing everything that was displayed before I clicked on the subfolder. I would like the tree to remain in the state that exists at the time a user clicks on a particular folder. thanks for your help.
