How do I implement a combobox (Netbeans 5.0+mobility pack)?

I'm trying to write a simple app for my cellphone (Samsung M500) The first screen needs to behave exactly like a combo box (a text box at the top and a listbox under it).I'm new to this and I can't figure it out yet.

Well you can use a List or a ChoiceGroup inside a form, this elemnts are shown and behave depending on its constructor. If you pass Choice.POPUP as parameter on the type then it will appear as a combobox.

But keep in mind that POPUP was added under MIDP 2.0 and is not available with MIDP 1.0
