[drupal-support] Controlling the form theme

Hi, I'm creating a form using form_group. I want the form to look like the following - dropdown1 dropdown2 dropdown3 The default behavior is giving me: dropdown1 dropdown2 dropdown3 This is an XHTMLTemplate (bluemarine). How do I go about getting what I want? I don't see the code in xtemplate.xtmpl. I've poked through the documentation - it doesn't look like I can do it with theme_x. Any hints - can someone point me to an implementation that deals with this? Thanks, Dan
