Offroad Contact Form

I wish to add radio buttons and popups to a contact form using the Offroad theme. They appear, but in a single horizontal line with no space between the options.
I tried using a different theme, and the radio options appeared in a column - the effect I require in Offroad.
Is there a simple solution?

There are some known issues with the Offroad theme. We suggest choosing another theme (built in or otherwise).
