Build a responsive mega menu in HTML, CSS, and Javascript. First of all, nothing can be more reliable than a flat, one-level menu. Though, the difficulty is that a simple menu is suitable for small sites only. But, when we need to build navigation paths for something that has more than ten pages, we are forced to create multi-level menus.
How to build a responsive mega menu
Let’s consider that a responsive mega menu is something that has a thick structure with various node levels. It is well known as the type of menu found on any large or middle-sized website where content managers need to represent a lot of data impossible to compress into a simple, one or two-level menu. Generally, mega menus include different media content to better visually represent the navigation categories of the website.
So, Let’s begin to create a mega menu with the help of HTML, CSS, and Javascript. First, you need to create a file with the name index.html or whatever you want. After that take a look below.

$(".mega > ul > li").click(function() {
var thismega = $(this).children("ul");
var prevState = thismega.css('display');
$(".mega > ul > li > ul").fadeOut();
if ($(window).width() < 943) {
if(prevState !== 'block')
thismega.fadeIn(150);}});
$(".mega-mobile").click(function (e) {
$(".mega > ul").toggleClass('show-on-mobile');
