Submenu character width - main navigation

Would like to change the width of the submenus on the main navigation menu. Reason is that some of our menu items end up wrapping which we don’t want. Is there a way to do this? Kerrpump.com

Hello there,

Try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

    #mainnav ul li ul {
      width: 280px;
    }
