Hi Quincey, Thanks for the reply. It seems I did not make myself clear. I did write that >> the Brand Combo Box must display a list of Brands for the user to select for >> that Product. but i also wrote >> . Also, when a user types in a new Brand instead of using the existing ones, >> the new Brand should also be added in the array of Brands for that >> particular Product. > So basically, i was only interested in the auto-complete (setComplete: method) of comboBox when I wrote the first sentence. But as you can see in the second sentence, I want the user to type in new Brands so that they are also available for auto-completion the next time. So I hope ComboBox is the right choice. Please guide me now.
