Then you show/hide the ones you need as appropriate. Defining the listboxes in the form editor was just the way I did it in the past. Also putting listboxes stacked on top of each other is something I am doing frequently Because I had to modify the listboxes on a regular basis (add columns in request of users) I decided to create them programmatically Why does 4D implement all these new (listbox) object commands?
