woocommerce issue

hey guys
i’m using the woo commerce plugin on my site and wanted to see if there is a way to disable the menu navigation at the top of the page. currently i have that navigation set up for my homepage to scroll down to the certain sections of the page. i’d like to be able to go back to the main page, but didn’t know if there is a way to set up a separate menu for a different page? so I either want to
1. change navigation to new menu that works on that page
2. disable top header completely so you can’t see the header.

thanks
