Select Multiple Items In JList Without Using The Ctrl/Command Key

Question

I am looking for a way to select multiple items within a JList by just clicking each item.

The normal way to do this is to hold the command/ctrl key and then click.

Answer 1

For that you'd normally use a checkbox group of JCheckBox items.

Users are already used with the fact that they need to press CTRL to select multiple items in a listbox. You should not change the default experience/expectation.
