Rails - Oct 2009 - Populate a combo box

Hi,
I am struggling with this problem: in a page there are 2 combo box:
category and subcategory. When I select a category the subcategory combo
must update its values.

I would like to use JQuery with Ajax to load subcategory after category
change.

It important the page works also without Javascript, Do you have some
idea to  accomplish that ?

thank you !

I''m assuming you mean list boxes here.  Comboboxes are slightly 
different.

observe_field should do it.

Yes.  You''ll need to submit the form after the category is chosen if 
you''re doing without JS.  There''s no other way.

I know that observe_field is a PrototypeHelper methods,
I am using Jquery, then is it better to use only JQuery methods ?
