Main menu tabs question

Hello, is there any way to make the main menu tabs not continue to the right like they do in the picture? What I mean is, with this layout and amount of main menu items that I have the menu stretches past the width of the template. Is there some way to make the menu two levels or do I just have to go in and edit the css myself to make the tabs thinner or something?

Thanks.

Unfortunately, tabs can't have two levels. You can increase template width or make tabs smaller. In example, you can use subtext. Name menu items as, in example Who||We are (use || as delimiter).
