Looking for Template Help - Secondary Navigation that is Same as Orange Theory...or special embedded options?

I'm currently using the Heights Template. I like how you can scroll through the homepage but would like some help on the Navigation side of things, particularly secondary NAV. I really like the secondary navigation for Orange Theory's website. When you hover over the main site navigation, a long bar with the sub-options comes up (and stays up) that goes across the entire page. Is there a Squarespace Template that is close to Orange Theory? Or is there a way I can embed some code to get this sort of secondary navigation? Thank you in advance. Matt
