Using Two Combo Boxes and moving items between them

Hi,

I'm currently a senior university student using Django for
a web
project. So far, I'm really enjoying using it, and plan on
utilizing it
for a few of my side projects, thanks for all the great
work. 

Right now, I have a question on if something is possible,
and if so,
ideas on how to do it.

I want to create a form that has a section with two combo
boxes, the
first combo box is a list of items. The user can then use
buttons to
move an item from one combobox to the other. The items in
the second
combobox I want to read in and set in the database/object.
Any thoughts
on this?

Thank you,

Chris

Unless I'm completely misunderstanding you, look at how the
admin
application handles many-to-many relationships with the
"filter_interface" property. It's generated by
these JavaScript files:

http://code.djangoproject.com/browser/django/branches/magi
c-removal/django/contrib/admin/media/js/SelectFilter2.js
(the actual code that generates it)

Check out ManyToManyField's
filter_interface=meta.HORIZONTAL option.
It's in the model docs.
