<div class="demo-description">
<p>Constrain the movement of each draggable by defining the boundaries of the draggable area. Set the <code>axis</code> option to limit the draggable's path to the x- or y-axis, or use the <code>containment</code> option to specify a parent DOM element or a jQuery selector, like 'document.'</p>
