How to put a dropdown in a NewEdit page

Hi, I was wondering how I could put a dropdown widget into a NewEdit page. The goal is for 'Productcode' and 'Categorie' to have a dropdown widget (with certain options) while entering data. I've tried this by changing the attribute types to ENUM, but sadly, this didn't work. Any type of help is much appreciated.
