multi-select

问题 I'm currently trying to change the default behaviour of a multiselect element, so that a user can select and deselect multiple values, without having to press the Ctrl key all the while.

The JComboBox API reports: The user can select a value from the drop-down list, which appears at the user's request. And a JComboBox tutorial: Lists are not terribly attractive, but they're more appropriate than combo boxes when the number of items is large (say, over 20) or when selecting
