JavaScript (I think it's the JavaScript but I'm not sure if it's true or not.)

$('.navTrigger').click(function() {
    $(this).toggleClass('active');
    console.log("Clicked menu");
    $("#mainListDiv").toggleClass("show_list");
    $("#mainListDiv").fadeIn();

});

Everything works fine on desktop, but on cell phones this fold out doesn't work.

Answer 1

Actually try this:

.navTrigger {
   z-index: 2
}

I believe perhaps on a very small device the main title is overlapping the navigation trigger.
