Fellow Zopesters, Here is a short tutorial on using the tree tag for global navigation in your site. Step 1: Create an external method with the following code: def getFoldersOnly(self): """Return a list of only the Folders contained in an object, for use by the tree tag""" return self.objectValues(['Folder']) This is neccesary in order to avoid listing the product and acl_users folder objects. Thanks to Kent Polk for the code. Modify this code if you want to display something other than just folders, For example: Step 2: Create a DTML method named SideBar in your root folder with the following code: <!--#tree branches=getFoldersOnly--> <A HREF="<!--#var BASE1-->/<!--#var tree-item-url-->"><!--#var id--></A> <!--#/tree--> Notice that we are generating absolute URL's. Thanks to Kent Polk and Martijn Pieters for this code. Step 3: Call SideBar with the following code from anywhere in your site using this code: <!--#var "SideBar(PARENTS[-1],REQUEST)"--> And voila! it should display a tree of your entire site structure! Thanks to Amos Latteier for this deceptively simple code snippet. I hope this helps others who may have been struggling with this. Michael Bernstein
