well, i think that i found the solution..
you need to edit in your includes/templates/YOUR_TEMPLATE/common/tpl_columnar_display.php file...
Note/PS: I have column grid layout module installed...
/* 'clear:both' in stylesheet did the trick */
the change in tpl_columnar_display.php is as under:
the above code was added just below this one:
if($col == (sizeof($list_box_contents[$row]) - 1))
echo "<br class=\"clearBoth\" />";
feeling lazy to describe all this
echo '<div' . $r_params . '>' . $list_box_contents[$row][$col]['text'] . '</div>' . "\n";
hope everyone will understand this.. if not, then you can implement this and try to understand.. even if you don't understand.. then please reply to this post..
