Compatible with StoreFront theme?

I’m not familiar with the Storefront theme, and it’s possible you might target the wrong class/ID of the main navigation, or that there is a conflict with any plugins you might have installed.

Do you have a link to your site where I can see the issue?

Site is https://www.reinke.re

I tested the plugin with the ids and classes

#site-navigation
.main-navigation
.primary-navigation
#menu-header-menu

but no stickiness…

Thanks for taking a look.

#site-navigation and .main-navigation should work, under normal circumstances ( = if there’s no conflicts).

Any chance you can activate the plugin again and use #site-navigation to see why it wouldn’t be working?

Give me a minute…

Done. WTF!?!?! It works!

Not correct because the content is scrolled through the menu, but I will try to figure out if that can be changed.

Hmm… how would I tell the content not to scroll through the menu?
How would I set the background color of the menu?

You can use CSS for that, something like this:

#site-navigation {
  background-color: #0000ff;
}

Of course, change the color to your liking.
