Select listed answers by moving them between two boxes
A very effective way of collecting answers is by using a list of options that users can pick from. It becomes even better if form users are able to move the options from one box to the other in relation to the question on the form.
Dual List-box is a different way of receiving form answers. It lists all the options you want your users to choose from in one box on the left, then require them to interactively move their selections to the box on the right. Pretty cool, right?
You can customize the titles of each box, as well as adding and modifying the list in the box on the left using the widget settings dialog - along with other settings that will help you customize the widget's layout further.
