This simple jQuery-plugin splits lists into columns.

• columns — columns number (default: 4)
• classname — column class, several classes need to divide the spaces (default: column)
• min — minimal number of columns (default: 1)

Also you can specify options via data-parameters: data-columns, data-classname, data-min.

<script type="text/javascript">
    (function($) {
        $(function() {
            $('#ol, #ul, .ol, .ul, ol, ul').autocolumnlist({
                columns: 5,
                classname: 'col',
                min: 3
            });
        })
    })(jQuery)
</script>
