That it because the theme you are using on the site has a problem of inserting unnecessary <br /> before each <select> tag. Try another theme.
I am using the Thesis theme and my entire site is styled so that changing the theme at this point will be too much work. It doesn’t insert the <br /> tag before any of the other tags though, the radio and checkboxes all work fine. Is there no other way to fix this?
I’m also having the same problem with this site: http://www.paazi.com/car-shopping-with-paazi-new-page/
This is, as you can see, a completely different theme.
Also on the above page (http://www.paazi.com/car-shopping-with-paazi-new-page/), how do I format the check boxes so that there are only 3 or 4 per line and that the check boxes and their labels stay together?
Thanks-
