Hi Dirso,
I've done something similar to what you are describing, using jQuery,
the dynatree jQuery plugin, and some reasonable Django code. The code
is available at http://bitbucket.org/tpherndon/django-fedora/, and
you'll specifically be interested in the djadora/views/browse.py and the
djadora/templates/fedora/browse_dynatree.html and image_fragment.html files.
I implemented the code as part of a special-purpose web app for
interfacing with a Java repository system, and the code is far from
clean and pretty, but it should give you a decent example of something
that is currently in production.
The way I approached it was to write a couple of views that are designed
to handle the jQuery dynatree Ajax requests. Dynatree does the work on
building the tree in HTML, my views provide the data, and the models
each have a "parent" attribute that allows the views to figure out how
to select children for each tree level.
In retrospect, I'd do my best to reuse django-mptt, django-treebeard, or
similar. They aren't a direct fit for my use case, since I have
different models that can contain each other, and from what I've seen
they are geared to handle only a single model class pointing to itself,
but I would follow their approach and steal code like crazy. :) Or, if
I had just one kind of model, I'd just add enough Ajax views to power
dynatree.
