I have not used jQuery for a long time, but I believe what you want is a Drop Down Menu Plugin, check out this link: link seems to me very simple to use, the site has examples of codes.

I hope it helps!

You can do this feat in many ways. A simple way to do it is with JS like this: 

            // nav
            $('#navbar-click').click(function() {
                if (!$('.nav').hasClass('open')) {
                    openMenu();
                } else {
                    closeMenu();
                }
            });

            function openMenu(){
                $(function(){
                    // console.log('click');
                    $('.nav').addClass('open').show(300);
                });
            }
            function closeMenu(){
                $(function(){
                    // console.log('click');
                    $('.nav').removeClass('open').hide(300);
                });
            }
            .nav{display: none;}
            ul{
                border: 2px solid #bdbdbd;
                background: #cdcdcd;
                border-radius: 2px;
                display: table;
                padding: 15px 15px;
                list-style: none;
            }
            #navbar-click{max-width: 50px;border: 3px solid #a2a2ab;border-radius: 5px;}

I do not remember some concepts about Class Arrays How to solve the problem of the variable's can not find symbol?
