I have a 10 digit product_id field which is "0" padded.
when a new product is added i automatically assign
the new product ID. When the users are looking up the product_id they scroll through the list with the mouse and pick the one they want.

I need to change this so they can just type in the combo box the
product_id they want. How do you make the combo box editable so it works both ways scroll down or user input.
