Howdy all..
I've read through the DTML Guide section on the tree tag as well as Tad Murphy's How-To, but I still can't get the tree tag to do what I want.
I have folders that are meant to be part of the site hierarchy as well as folders that are simply used to clean up the management view of the site. For example, I have an Images folder at the top, but I don't expect users to browse to http://site/Images, so I don't want that folder to appear in the nav tree. If I add a property called 'hidden' to such folders and use the following code: <dtml-tree expr="PARENTS[0]" skip_unauthorized=1 sort=title_or_id branches_expr="objectValues(['Folder', 'Squishdot Site'])"
<dtml-if hidden> <!--Skipping hidden--> <dtml-else> <a href="<!--#var absolute_url-->"><!--#var id--></A> </dtml-if> </dtml-tree> Then the tree is still rendered with the 'hidden' folders but with no text etc. That is, it takes up space in the tree and shows a plus if it has subfolders. What I would like is that such folders (and their subfolders) are not rendered at all.
I'm thinking I have to provide some code in place of the objectValues(['Folder', 'Squishdot Site']) that returns the same minus said items that have 'hidden' as a property, but I don't understand whether this 'code' would be a DTML method or an external method, or what 'type' of this it would return (a list?).
Indeed, you'd need to replace the objectValues method. Lucky for you, someone already wrote such a method for you.
