How can, This values divided between the three columns with CSS and width: auto; as dynamic?
As this: http://img4up.com/up2/20239064020416631754.gif
Example: http://jsfiddle.net/r3rm9/
<ul>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
<li>6</li>
<li>7</li>
<li>8</li>
<li>9</li>
<li>10</li>
<li>11</li>
<li>12</li>
</ul>
You can start with the CSS3 Column properties, but support isn’t very good at the moment.
