How to prevent JComboBox from closing?

Question

After selecting an item from a JComboBox, i want to keep the JComboBox still opened to allow the user to choose another item from it. Is that possible ?

I hope you can provide me an example.

Answer 1

As a different approach, maybe you can display in the JComboBox only the "allowed to choose" items in first place?

Answer 2

Perhaps what you are after is a JList instead.
