<p>Snap the draggable to the inner or outer boundaries of a DOM element. Use the <code>snap</code>, <code>snapMode</code> (inner, outer, both), and <code>snapTolerance</code> (distance in pixels the draggable must be from the element when snapping is invoked) options. </p>
<p>Or snap the draggable to a grid. Set the dimensions of grid cells (height and width in pixels) with the <code>grid</code> option.</p>
