How do you format the exposed filter options?
Views 3 for Drupal 7 kindly gives each exposed widget DIV a class with a unique name. Then it's a matter of adding clear and float attributes. 

If you're using Views 2 you will have to override the views-exposed-form.tpl.php file in the views/theme folder. You can just copy and save this code in a file called views-exposed-form.tpl.php in your theme file path. It should override the original template file.

&lt;?php
// $Id: views-exposed-form.tpl.php,v 1.4.4.1 2009/11/18 20:37:58 merlinofchaos Exp $
/**
 * @file views-exposed-form.tpl.php
 *
 * This template handles the layout of the views exposed filter form.
 *
 * Variables available:
 * - $widgets: An array of exposed form widgets. Each widget contains:
 * - $widget-&gt;label: The visible label to print. May be optional.
 * - $widget-&gt;operator: The operator for the widget. May be optional.
 * - $widget-&gt;widget: The widget itself.
 * - $button: The submit button for the form.
