Remove megamenu all together?

Hi, I'd like to remove the default menu that comes with corporate2, and put in a different style menu...how easy is this to do? There's no options in back-end to turn it off...do I need to just display:none some of the css?

site is vitaloximeters.co.uk

Thanks,

Olly

there is 5 different menu styles with this... megamenu - splitmenu - css menu - moo menu - dropline menu...

u can change it in extentions > templates > corporate 2 > menu > menu type...

Is there a way to turn if off completely?
