Hello,
If you are still struggling with the menu, I've put together a 100 page document (pdf download for a small fee) and website (free) which demonstrates all of the CSS classes for DotNetnuke, including the Solpart menu. - This will be released as issue 10 of the magazine.
I've still got to add a couple of articles to the site, but the majority of the content is now complete so thought you would find it useful:
