Tree View/Navigation in XForms

I am wondering.. is tree view/navigation possible to do (and somewhat easily) in XForms given a XML data structure?

If it is possible, where can I find a really excellent example (code and hopefully a work开发者_C百科ing form to view)?

Also, are there any tips you have for implementing this? (I'm new to XForms, and only know the basics so far)

Thanks so much!

:D

I am not sure what you mean exactly by "tree navigation", but if you have a tree-like structure with arbitrary nesting in XML, and want to show it to end-users as a tree, you can if using Orbeon Forms, you can use the appearance="xxforms:tree" on a <xforms:select1> or <xforms:select>. See for instance:

http://wiki.orbeon.com/forms/how-to/icons-tree

This will be rendered as a tree on you web page, e.g.:
