How to turn off mobile menu at Twenty Sixteen?

I think the simplest way would be to use the following CSS

@media screen and (max-width: 768px) {
	.site-header-main .site-header-menu {
		display: block;
	}
}

Thanks for the code. Unfortunately it doesn’t work. I still the menu on mobile is still hiding and I have click on the button to open it. See? https://imgur.com/a/YKmvDaJ

Hi, I tried again on my default Twenty Sixteen install and it is working for me in Chrome on OSX. Do you have a live site where you tried adding it into and it isn’t working so I can take a closer look?

Hello,

sure, my website is https://liborsmolik.com/

I applied your code into CSS but it’s the same. On mobile, I still have to click on menu button to expand it. I would like to have the menu expanded all the time and make button disappear.

Thanks, try the following as it looks like it should work

@media screen and (max-width: 768px) {
	.site #secondary {
		display: block;
	}

	.site .secondary-toggle {
		display: none;
	}
}
