How can I get the same result using WP Show Posts In GeneratePress?

Hello, LEO!

It is working good thanks for the help.

It was also working for mobile before but I have activated the Mobile Header to use a different logo on mobile view.

Now it is not showing shadow for primary mobile menu and sticky as well.

Add this:

@media (max-width: 768px) {
    #mobile-header {
        box-shadow: 0 5px 8px -1px rgba(0,0,0,.4);
        position: relative;
    }
}
