citbagheria on "[Theme: Hueman] Impossible to see menu from home page into the smartphone"

I have analyzed some of the files and the problem could be here. Can you help? This file is: scripts.js

/*  Mobile menu smooth toggle height
/* ------------------------------------ */
	$('.nav-toggle').on('click', function() {
		slide($('.nav-wrap .nav', $(this).parent()));
	});

	function slide(content) {
		var wrapper = content.parent();
		var contentHeight = content.outerHeight(true);
		var wrapperHeight = wrapper.height();

		wrapper.toggleClass('expand');
		if (wrapper.hasClass('expand')) {
		setTimeout(function() {
			wrapper.addClass('transition').css('height', contentHeight);
		}, 10);
	}
	else {
		setTimeout(function() {
			wrapper.css('height', wrapperHeight);
			setTimeout(function() {
			wrapper.addClass('transition').css('height', 0);
			}, 10);
		}, 10);
	}

	wrapper.one('transitionEnd webkitTransitionEnd transitionend oTransitionEnd msTransitionEnd', function() {
		if(wrapper.hasClass('open')) {
			wrapper.removeClass('transition').css('height', 'auto');
		}
	});
	}

});
