Looking for a jQuery sortable boxes library
<p>I am looking for a jQuery (or pure JS) sortable boxes library.</p>

<p>Functionality should be similar to <a href="http://jqueryui.com/demos/sortable/#display-grid" rel="nofollow">http://jqueryui.com/demos/sortable/#display-grid</a></p>

<p>However, that's not enough. What I need is:</p>

<ul>
<li>Sortability within a grid</li>
<li>Resizable boxes</li>
<li>Taller boxes should not leave blank space on the left side (this is a problem with jUI  sortable)</li>
<li>Resizing / dragging should be done on a grid basis e.g. 32x32 not per pixel because that's too precise.</li>
</ul>

<p>The jQuery UI fails with resizability. When I make boxes resizable, and I resize a middle box to become tall, then the leftside of the box is empty (because the other boxes don't float to the left).</p>
