Checkbox list widget improves usability of standard multiple-select input controls replacing them with a more intuitive to use, scrollable checklist that allow multiple options to be selected with just the mouse and without taking up a lot of screen.
This solution uses a different user-interface that accomplishes the same result as the multi-select list box and can simplify forms for novice users. The server side script receives the same values in both cases.
The biggest problem with multiple-select boxes is that selecting multiple options is a pain for average user, especially if there are enough options to create a scrollbar within the box. User have got to hold down the appropriate modifier key (Ctrl on Windows, Command Button on Mac) in order to do so. While experienced users are familiar with this user-interface paradigm, for many new inexperienced users this is not very discoverable.
For example, let's say you are building a form where users should indicate the countries they have been. To accomplish this, a multiple-select box is usually shown with all the countries in the world as options. The users would have to hold down a key and select each country they need. This may include scrolling within the box and if like using the scroll wheel on mouse, and then you may click in the box again to enable focus and start scrolling down. Just clicking without holding the modifier key deselects all the previously-selected options and users have to go back and remember what were picked before.
When the widget is applied to multiple-select box, the result is a scrollable checklist, where users can search and select multiple items without all the hassle of worrying about deselecting previously-selected options.
