Hi when setting the menu (top navigation) style to fixed and there are submenu if the header breaks to 2 lines then the submenu will open but hide behind the second line. I know not really good explanation so please check oregonrenewablecities.org and you will understand what I’m saying as sson as you resize your browser window.
We are aware of this, unfortunately there is no easy solution (changing the order in which the elements are rendered would break submenus animations). One workaround is to try to use less menu items (when submenus are also used) so that the menu doesn’t jump to two rows on medium devices (before it switches to the mobile menu).
