MySQL Data Columns overflow into a second row wish CSS

[aliased]

I know there is the CSS column count CSS style but I really need help with some codeWhat I'm trying to do is output my categories into 2 columns like this\[code\]Category 1 | Category 2Category 3 | Category 3Category 4 | Category 5\[/code\]From left to rightThis is my current SQL\[code\]<?php$sql = mysql_query("SELECT * FROM wss_cats WHERE parent_id = 0 ORDER BY cat_order");$total_cats = mysql_result(mysql_query("SELECT COUNT(*) as Num FROM wss_cats WHERE parent_id = 0"),0);$total_cats2 = 0;if ($setting['all_wallpapers'] == 1) { $url = CategoryUrl(0, 'all', 1, 'newest'); echo '<a href="'.$url.'">'.ALL_WALLPAPERS.'</a>'.$template['categories_menu_seperator'];}while($row = mysql_fetch_array($sql)) { $total_cats2 = ($total_cats2 + 1); $seo_name = seoname($row['name']); $url = CategoryUrl($row['id'], $row['seo_url'], 1, 'newest'); echo '<a href="'.$url.'">'.$row['name'].'</a>'; if($total_cats2 != $total_cats) { echo $template['categories_menu_seperator']; }}?>\[/code\]Which only displays in 1 column in alphabetical order which I also want to keep.
