Yes. If you want to use AJAX, you will need a separate view, taking
manufacturer id or slug and returning
1. either the HTML with the collection select field, which should
replace a default collection select field,
2 or the JSON-based collection options, which should replace the
options of the collection select field, iterating through all the
received items.
Learn yourself, how to use yahoo-provided library. Don't forget to
check user permissions in the custom views for AJAX.
An alternative to AJAX would be to overwrite the admin template for
the style model and use some custom template tag which would return a
complex array structure with manufacturers and corresponding
collections.
