single.php for one specific category?

Hi all,

I’ve trawled the supports forums and can’t quite find an answer so maybe someone can point me to it? ??

I’m using WP as a CMS. I have numerous categories for the blog, and one, called Portfolio, for my work. When I click the post title in Portfolio, I want it to be displayed completely differently from how all my ‘Blog’ posts are.

Is there anyway of pointing the post to a different ‘Single.php’ for it to be displayed properly?

Thanks in advance.
