title: draggable multiselect jquery
body: <p>I want to create a multiselect with draggable option. But I couldn't wrote and found myself. My <strong>options</strong> have their <em>priority</em> (the order in the list). So ex. when I drag the second item to the first place then the priority of item1 will be 2 but item2 will be 1. Additionally I can select (multiple) options.</p>
