In your custom CSS plugin, add these two rules:
#navigation .menu-toggle {
display: none;
}
#navigation ul.menu {
display: block;
}
The first rule will prevent the hamburger menu from displaying and the second will always display the main nav menu.
Thanks CrouchingBruin, perfect for the header menu!
Any idea how to get the header smaller on mobile devices? I’d rather not have it completely hidden, it’s just a bad content experience if header + headline + ad = 150% of an iPhone 6 display height.
