Milonic JavaScript Menu

Would really appreciate some help and guidance with this one.

The menu is positioned within a <div> tag (using CSS for layout), whilst the main part of the nav postions itself fine, the submenu items (click on a section header to show) are positioning ...

Ok, I've purchased a license, downloaded the latest DHTML nav, but have no idea how to integrate the collapsible menu into it. If anyone can help me out here I'd be most appreciative as I've got little hair left to pull out!!!

Thank you in advance!

David.
