Discussion on:

Creating multicolumn lists

Another option, the neatest one and most correct semantically, is to use nested lists, where each column would be a list item in an inline list, each containing a list of items.

The markup and a simple style would be something like:

<style>
ul { float: left; list-style: none; }
ul li {display: inline; }
ul li ul li { display:block; }
</style>
<ul>
 <li>
  <ul>
   <li>Item one</li>
   <li>Item two</li>
   <li>Item three</li>
  </ul>
 </li>
 <li>
  <ul>
   <li>Item four</li>
   <li>Item five</li>
   <li>Item six</li>
  </ul>
 </li>
 <li>
  <ul>
   <li>Item seven</li>
   <li>Item eight</li>
   <li>Item nine</li>
  </ul>
 </li>
</ul>

Of course, the same applies to ordered lists.

What the ****?
Are you braindead?

You can also create multi column lists using display:inline for li.

li {
width:180px;
margin:15px 0 0 0;
padding:0 10px 0 0;
line-height:15px;
float:left;
display:inline;
}
