how to do sorting in ROR

Hi, are the list box items being retrieved from the DB? If so, you
can simply use the ':order' within the find method of your model. For
example,

orders = Order.find(:all, :order => ["pay_type, shipped_at DESC"],
:conditions => "id = ?", 25 )

If not, please provide more information as to how you're populating
the list box.

Good luck,
