Fiddle (and CSS):

HTML:

<div class="group">
    <h1>Group 1</h1>

    <ul class="parent">
        <li class="droppable"><span class="draggable">Item 1</span></li>
        <li class="droppable"><span class="draggable">Item 2</span></li>
        <li class="droppable"></li>
    </ul>
</div>

<div class="group">
    <h1>Group 2</h1>

    <ul class="parent">
        <li class="droppable"><span class="draggable">Item 3</span></li>
        <li class="droppable"></li>
        <li class="droppable"><span class="draggable">Item 4</span></li>
    </ul>
</div>​

JavaScript:

    revert: true,
    revertDuration: 0
