 <p>Yes there are plugins that offers this functionality, I think most of the drag and drop jQuery plugins has their own callback function that triggers once the dragging and dropping has finished. <a href="http://dragsort.codeplex.com/" rel="nofollow">jQuery List DragSort</a> is a plugin I've used in my project before, it's lightweight and easy to use.</p> <pre><code>$("menu").dragsort({dragEnd: showHiddenCells }); function showHiddenCells() { //triggers after the user drops the element } </code></pre>
