CSS: Failing to display unless refreshed - Navigation bar

I have been working on navigation bar and the strangest issue is occurring.
Please use the JSFiddle link to see what I mean.
To duplicate the error:
Run the code when the desktop view is active i.e. when the navigation links are in a line.
Then resize the screen till the "click me" is displayed.
Then press it.
Now run the code while you see the "click me" and press it again.
JS information
jQuery(document).ready(function($) {
// UserCP
$('.rotate').on('click', function() {
$(this).toggleClass("down");
});
$('.nav-start').on('click', function() {
$("#nav2").removeClass("hidden");
$('#nav2 li a').stop().slideToggle('100');
return false;
});
$(document).ready(function() {
$('#nav2 li a').stop().slideToggle('100');
});
$('body').on('click', function() {
$('#nav2 li a').stop().slideUp('100');
});
$("#nav2 li a").click(function(e) {
e.stopPropagation();
});
$(document).click(function(event) {
if (!$(event.target).closest('#nav2 li a').length) {
if ($('#nav2 li a').is(":visible")) {
$('html, body').on('click', function() {
$('#nav2 li a').stop().slideUp('100');
});
};
};
});
});
FIXED - UPDATED JSFiddle! Thanks #Louys Patrice Bessette #Titus #Rick

You are using two click events on this "Click me" li...
(One on .navstart and one on .rotate)
It may not be an issue, but this make the code harder to read.
Then, when you slideToggle(), if you want the submenu to slide down, it has to be hidden.
Because, since you remove the hidden class (probably usefull on load), the submenu is visible.
A Toggle hides it.
I simplified your script to this.
Have a look at this updated Fiddle.
$(document).ready(function() {
// Show submenu on "Click me"
$('.nav-start').on('click', function() {
$('.rotate').toggleClass("down");
$("#nav2").removeClass("hidden");
var subNav = $('#nav2 li a');
if(subNav.css("display")=="block"){
subNav.stop().slideUp('100');
}else{
subNav.stop().slideDown('100');
}
return false;
});
$("#nav2 li a").click(function(e) {
e.stopPropagation();
});
// Hide submenu on document click
$(document).click(function(event) {
if (!$(event.target).closest('#nav2 li a').length && $('#nav2 li a').is(":visible")) {
$('#nav2 li a').stop().slideUp('100');
};
});
});

Broken Multi-Tier JQuery Accordion

JSFiddle
http://jsfiddle.net/5rkrq4bw/strong text
JQuery Code
// Side Menu Starts
$('.SideNav .Menu a.MenuDrop').click(function(event){
event.preventDefault();
if(!$(this).hasClass('Active')) {
if(!$(this).parent().parent().hasClass('Active') && $(this).next().hasClass('sub-menu')) {
$(this).next().slideToggle();
$(this).addClass('Active');
} else {
$('.SideNav .Menu li ul').slideUp();
$(this).next().slideToggle();
$('.SideNav .Menu a.MenuDrop').removeClass('Active');
$(this).addClass('Active');
}
}
});
//Side Menu Ends
The Problem
Trying to integrate multiple tiers I am finding the problem of only being able to have one open at a time and checking to see if any others are open to close them.

JQuery Code:
(function(jQuery){
jQuery.fn.extend({
accordion: function() {
return this.each(function() {
var $ul = $(this);
if($ul.data('accordiated'))
return false;
$.each($ul.find('ul'), function(){
$(this).data('accordiated', true);
$(this).hide();
});
$.each($ul.find('a'), function(){
$(this).click(function(e){
activate(this);
return void(0);
});
});
var active = $('.Active');
if(active){
activate(active, 'toggle');
$(active).parents().show();
}
function activate(el,effect){
if (!effect) {
$(el)
.toggleClass('active')
.parent('li')
.siblings()
.find('a')
.removeClass('active')
.parent('li')
.children('ul, div')
.slideUp('fast');
}
$(el)
.siblings('ul, div')[(effect || 'slideToggle')]((!effect)?'fast':null);
}
});
}
});
})(jQuery);
Usage:
Link to JQuery and the above script
Make a multi-level list
Give your list a class/ID name such as '.SideNav'
Tell the script this is your accordion $('.SideNav').accordion();

http://jsfiddle.net/sabithpocker/5rkrq4bw/2/
$('.SideNav .Menu a.MenuDrop').click(function(event){
event.preventDefault();
console.log(this);
var subMenuToExpand = $('ul.sub-menu', $(this).parent());
var otherVisibleSubMenu = $('ul.sub-menu:visible', $(this).parents('.Menu'));
otherVisibleSubMenu.hide();
subMenuToExpand.show();
});
$('.SideNav .Menu a.MenuDrop').click(function(event){
$('ul.sub-menu:visible', $(this).parents('.Menu')).slideUp(50);
$('ul.sub-menu', $(this).parent()).slideDown();
});

Close active accordion item

I found this sweet accordion menu and I want to modify it a little bit. I want to add a close function, so if I click on the h2 that's active it will slide up and close. How can I achieve that?
$(function() {
$('#accordion .content').hide();
$('#accordion h2:first').addClass('active').next().slideDown('slow');
$('#accordion h2').click(function() {
if ($(this).next().is(':hidden')) {
$('#accordion h2').removeClass('active').next().slideUp('slow');
$(this).toggleClass('active').next().slideDown('slow');
}
});
});
http://jsfiddle.net/tovic/CzE3q/

You need to check to see if the item you clicked on already has the active class. Try this:
$('#accordion .content').hide();
$('#accordion h2:first').addClass('active').next().slideDown('slow');
$('#accordion h2').click(function () {
var openPanel = !$(this).hasClass('active')
$('#accordion h2').removeClass('active').next().slideUp('slow');
openPanel && $(this).toggleClass('active').next().slideDown('slow');
});
Example fiddle

Add an else block to the click event handler that closes the pane if it is not hidden.
$(function() {
$('#accordion .content').hide();
$('#accordion h2:first').addClass('active').next().slideDown('slow');
$('#accordion h2').click(function() {
if($(this).next().is(':hidden')) {
$('#accordion h2').removeClass('active').next().slideUp('slow');
$(this).toggleClass('active').next().slideDown('slow');
}else{
$('#accordion h2').removeClass('active').next().slideUp('slow');
}
});
});

JS Dropdown menu not closing?

So I found this fiddle here: http://jsfiddle.net/8qPvp/4/
I thought I'd use it just for personal education purposes.
I'm really new with JS, and I noticed that the opened parent does not go back on click, like it opens. How could this be fixed?
$(document).ready(function () {
$("li").click(function () {
$('li > ul').hide();
$(this).children("ul").toggle();
});
});

What about this:
$("li").click(function () {
$('li > ul').hide();
$(this).children("ul").toggle();
});
$(document).click(function()
{
$('li > ul:visible').hide();
})
$('.menu li').click(function(e)
{
e.stopPropagation();
})
So by default i make whenever there is clicked ANYWHERE in the document, your visible menu will be hidden. However you don't want this to happen when you open a new menu(would be; made visible and made hiden directly). So i make a exception that catch when you want to open a new menu and i'll cancel the document click event.I use event.stopPropagation() to cancel a event.
jsFiddle

$(document).ready(function () {
$("li").click(function () {
$('li > ul').hide();
$(this).children("ul").toggle();
}).mouseleave(function(){
$(this).children("ul").hide();
});
});

How to add a class onto the selected li element and make li full-sized-clickable

I want to add a class to the selected 'li' and at the same time, remove the class:selected from previous selected li element.
I have worked on it hours and still haven't got any luck. I also checked others questions, but their solutions don't work for me.
Help please....
<ul id='mainView' class='menu' style='float: left; clear: both;'>
<li>Patient</li>
<li>Recommendations</li>
</ul>
<script type="text/javascript">
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').className = '';
alert($(this).attr('id'));
$(this).attr('class') = 'selected';
});
});
// $('.menu li').on('click', function () {
// $('.menu li.selected').className = '';
// this.className = 'selected';
// });
</script>
Update:
I did put a inside li, but if I click on the li not the a inside of the li, the webpage does not redirect. That's the reason why I do it in a reversed way.
Update 2
The reason why the selected li does not get the "selected" class is because the whole webpage is redirected to a new page which has the same navigation bar.
So now the question is how to highlight the selected li(it was selected on the previous page) on the new webpage.

Inside an UL everybody (even a browser) is expecting to see a LI
so your HTML:
<ul>
<li>Patient</li>
<li>Recommendations</li>
</ul>
And your jQ:
$('ul li').click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
});
Building web pages you should know how to treat LI elements. Simple, like dummy containers with minimal styling.
That means that you rather add a display:block ... float:left and other cool stuff to the <A> elements, than setting a padding there you go with your full-sized-clickable A elements.
Additionally (if you don't have time to play with CSS) to make a LI fully clickable use:
$('ul li').click(function(){
var goTo = $(this).find('a').attr('href');
window.location = goTo ;
// $(this).addClass('selected').siblings().removeClass('selected'); // than you don't need this :D
});
After the OP late edit - and to answer the question
After the pages refreshes to get which one is the active one use:
// ABSOLUTE PATH
var currentPage = window.location;
// RELATIVE PATH
// var currentPage = window.location.pathname;
$('li a[href="'+ currentPage +'"]').addClass('selected');

<script type="text/javascript">
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').removeClass('selected');
alert($(this).attr('id'));
$(this).addClass('selected')
});
});
</script>

Try addClass and removeClass, they're jQuery functions:
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').removeClass("selected");
$(this).addClass('selected');
});
});
