I've been looking for a navigation menu/sitemap for ZOPE. I've found a few but the output is not very well formed.

Essentially every tool I've found outputs something similar to this:

<div class="item" style="text-indent:35"> <!-- this is a parent element //--> Item </div> <div class="item" style="text-indent:65"> <!-- this is a child element //--> Child Item </div>

The problem here is that the html structure doesn't intrisicly show any relationship between the two levels. The code just shows levels by using text-indent or margins or in some code table cells. What I'm looking for would display the sitemap/navigation in a format like this:

<ul> <li>Item <ul> <li>Child Item</li> </ul> </li> </ul>

This structure has the element relationship built in by design. Does anyone know of a product that does this or have a code snippet they could pass my way.

Here's something that I use for generation of a navigation tree. You can simplify it by removing the highlighting stuff and the styling stuff that interfaces with TransMenus (http://personal.archomai.org/transMenus.php). Some things specific to my code and probably not yours: - course: a previously defined value for the object the tree should start at. You could use 'root' or 'context' or something else. - equivalency test: mine is for Archetypes objects. You'll need some other testif you don't have UIDs. - children listing: mine is project-specific. You can probably use 'objectValues' or 'contentValues' - groupishness: again, mine is project-specific, an attribute on groupish types. You could use truthfullness of the children-listing as above. Also, I've previously posted several times a simpler recursive tree-walker that works similarly, but with less METAL magic.
