Remove menu bar

Hello,

I can’t figure out my problem…

I have found a really nice theme but is it old.

http://www.chichihua.nl

Because i’m selling one product I need to have woocommerce.

The theme doesn’t support menus and so all the pages will come up in the menu bar. I can make a custom menu in a widget and that is what I will do.

I only need to remove the menu bar on the top…

With which code can I do that??

Hope someone can help me!
