Hi Zopsters, I need to build a navigation tree that has has only the leaf-folders hyperlinked. (Two frame design: left frame navigation, right frame some kind of property page, but only for the folders that are leaves in the tree.)

so: in the tree tag, how do I find out whether an element is a leaf or not?

Any kind of help is extremely welcome.

Right now, no special variable is set to inform you wether or not an item has sub items. The only way to discover wether or not there are subitems, is by calling the same method as the tree tag calls to determine the children of the current node, and see if it returns anything. So, supposing you do a tree of your Folder objects: <dtml-tree branches_expr="objectValues('Folder')"> </dtml-tree> Then you could test on "objectValues('Folder')": <dtml-unless "objectValues('Folder')"> This is a leaf, so make a hyperlink! </dtml-unless> -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
