Also see my answer to this question, which is very similar and has example code you can use in the HTMLSnippet widget.
Hi David,
The platform does not have a default option for this but there are several widgets in the appstore that allow Javascript execution or DOM node manipulation. With these you should be able to get this working.
Ah, this is really great, and I think I might be able to figure it out from this, but is there somewhere documentation of the NavigationTree widget and what the internal variables to set for this kind of behaviour would be? I'm not finding anything obvious from Google searching.

Maybe this is something that would be obvious if I was more familiar with Dijit, but I'm just kind of getting into it, and I'm not finding anything obvious from Google searches.
