Scroll Nav in Wordpress not working

I want to create a 'scroll-nav' for my website. So I separated 2 Navs and added some jquery:
<nav class="main-nav clearfix">
<?php wp_nav_menu(array('theme_location' => 'main_nav')); ?>
</nav>
<nav id="scroll-nav" style="display:none">
<?php wp_nav_menu(array('theme_location' => 'main_nav')); ?>
</nav>
$(window).scroll(function() {
if ($(window).scrollTop() > 50 ){
$('#scroll-nav').css('display', 'block');
} else {
$('#scroll-nav').css('display', 'none');
};
});
But it´s not working. Do I have to do something different because of WordPress? It tested it in a normal html, it works fine there.

You are putting clearfix like ID when you have to do it in class attribute.
<nav id="scroll-nav" class="clearfix" style="display:none">
And put your
$(window).scroll(function() {
if ($(window).scrollTop() > 50 ){
$('#scroll-nav').css('display', 'block');
} else {
$('#scroll-nav').css('display', 'none');
};
});
into
$(document).ready(function(){
});

JavaScript + CSS Single Collapsible Vertical Menu

Everybody, I have been learning and trying to make a collapsible vertical menu using JavaScript and CSS.
What should I do so that when I expand both menus and I click again on user 1, the user 2 will be hidden?
Here's the coding:
body {
background:#ffffff;
margin: 0 auto;
}
#nav{
width: 200px;
padding: 0;
margin-bottom: 0px;
font-size: 10px;
font-family: Verdana;
color: #999999;
}
#nav ul {
list-style: none;
margin: 0;
padding: 0;
border: none;
}
#nav li {
border-bottom: 1px solid #fff;
margin: 0;
width: auto;
}
li ul {
border-bottom: 1px solid #000000;
border-top: 1px solid #000000;
position: relative;
display:none;
}
ul li a {
display:block;
text-decoration: none;
color: #000000;
background: #8CDD81;
line-height:2em;
height:2em;

You can use jQuery to reduce your coding efforts.
Following is the only code you need.

background: #ffffff;
margin: 0 auto;

#nav {

font-family: Verdana;
color: #999999;
}
#nav ul {
list-style: none;
margin: 0;
padding: 0;
border: none;
}
#nav li {
border-bottom: 1px solid #fff;
margin: 0;
width: auto;
}
li ul {
border-bottom: 1px solid #000000;
border-top: 1px solid #000000;
position: relative;

I made this nav menu for reference. It's responsive to screen size too.
var btn = document.getElementById('navBtn');
var ul = document.getElementById('navUl');
btn.addEventListener("click", function(){
ul.classList.toggle("active");
});
#bar {
position: fixed;
top: 0px;
left: 0px;
width: 100%;
background-color: #333;
}
nav ul {
list-style: none;
padding: 0px;
margin: 0px;
}
nav ul li {
display: inline-block;
}
nav ul li a {
display: inline-block;
padding: 20px;
color: #fff;
font-family: Verdana;
text-decoration: none;
}
nav ul li:hover {
background-color: #666;
}
#navBtn {
display: none;
}
#media screen and (max-width: 500px) {
nav ul li,
nav ul li a {
text-align: center;
display: block;
}
nav ul {
display: none;
}
nav ul.active {
display: block;
}
#navBtn {
display: block;
width: 60px;
height: 60px;
border: 1px solid #fff;
background-color: #333;
color: #fff;
}
}
<div id="bar">
<button id="navBtn">☰</button>
<nav>
<ul id="navUl">
<li>home</li>
<li>news</li>
<li>contact</li>
<li>about</li>
</ul>
</nav>
</div>
As a side note, you can also technically do this with pure CSS (though, that's a bit tricky; you'd use a checkbox w/ labels for it).
Also, I saw your className = code, so I wanted to specifically point out the Element.classList bit in my code. It comes with .add(), .remove(), .toggle() and other useful methods.

HTML/CSS Jquery hover not showing up

I am new to Jquery and
I am trying to make a dropdown on my navigation using simple Jquery hover effect, and I think I am using wrong selector on Jquery.
I would like to see the dropdown and be able to navigate when i hover over 'What's New'
Any help would be awesome. Thanks,

You should use a nested ul for your dropdown menu. You don't need jQuery at all for this. It can all be done with CSS. Take a look at this simple hover effect under the Products tab.

Your submenu is hidden with visibility: hidden style.
I also separated the handled so that the menu doesn't hide while you're hovering it, and added finish() so that we're not queueing animations.
But yeah, like ncox85 said you should do this with css.
$(document).ready(function () {
$('.nav-level-2').hide();
$("li .nav-level-1").mouseenter(
function () {
$('.nav-level-2').finish().slideDown('200');
}
);
$("li .nav-level-2").mouseleave(
function () {
$('.nav-level-2').finish().slideUp('200');
});
});
.main-nav {
background: #000;
height: 30px;
position: relative;
overflow: visible;
z-index: 2;
width: 100%;
left: 0;
cursor: default;
}
.main-nav .inner{
height: 100%;
}
.main-nav>.inner{
text-align: justify;
}
.nav-links-container {
position: static;
/* background: red; */
height: 100%;
}
.nav-links{
padding: 0 0 0 3px;
display: inline;
margin-bottom: 20px;
overflow: hidden;
/*background-color: green; */
}
li {
vertical-align: top;
padding: 5px;
display: inline-block;
/* background: blue; */
}
li>a {
color: #FFF;
font-size: 12px;
letter-spacing: 1px;
text-transform: uppercase;
padding: 10px 9px 9px;
margin: 0 -3px;
}
li>a:hover {
background-color: white;
color:#000;
}
.nav-level-2 {
position: absolute;

left: 0;

border-bottom: 5px solid #000;

Just use display:none instead of visibility:hidden on class .nav-level-2

If any of you are wondering, I got a good result from just using html/css, got rid of jquery.
Maybe I will use jquery another time. fun lesson for myself and those of you out there. Thanks guys

Dropdown menu for webpage

I created a simple website for practice purposes. I'm trying to create a dropdown menu for the Items in navigation but when I ran the website, it doesn't show anything. All files are saved in desktop.
Here is the code for my html(main.html) with jquery(jquery-1.3.2.min.js):
function mainmenu() {
$(" #nav ul ").css({
display: "none"
});
$(" #nav li ").hover(function() {
$(this).find('ul:first').css({
visibility: "visible",
display: "none"
}).show(400);
}, function() {
$(this).find('ul:first').css({
visibility: "hidden"
});
});
}
$(document).ready(function() {
mainmenu();
});
body {
font-family: 'lucida grande', Tahoma, Verdana, Arial, sans-serif;
background-color: #e9e9e9;
}
#wrapper {
width: 1080px;
margin: 0 auto;
padding: 10px;
border: 5px solid #dedede;
background-color: #fff;
}
#banner {
height: 200px;
border: 3px solid #E3E3E3;
background-color: blue;
background-repeat: no-repeat;
background-size: cover;
}
#navigation {
height: 60px;
border: 3px solid #E3E3E3;
margin-top: 20px;
margin-left: 5px;
margin-right: 5px;
background-color: red;

Yes the error is inside your code. You are trying to target the first ul inside the li but in your code you the ul is standalone/ outside the li.
<li>Items
</li>
<ul>
<li>T-Shirt
</li>
<li>Pants
</li>
<li>Accessories
</li>
</ul>
see the ul is out side the Items li, put it inside and it will work like this.
<li>Items
<ul>
<li>T-Shirt
</li>
<li>Pants
</li>
<li>Accessories
</li>
</ul>
</li>
You were putting a ul inside a ul directly.

The problem is not with your jQuery but with the HTML, you should wrap your dropdown menu (ul) with items (li)
function mainmenu() {
$(" #nav ul ").css({
display: "none"
});
$(" #nav li ").hover(function() {
$(this).find('ul:first').css({
visibility: "visible",
display: "none"
}).show(400);
}, function() {
$(this).find('ul:first').css({
visibility: "hidden"
});
});
}
$(document).ready(function() {
mainmenu();
});

div inside a div is not accepting any input + html

I have a vertical navigation bar on my website. When I click on a link in the navigation bar the content is shown in the content div. My problem is that content that is shown in the content div is a form and it is not accepting any input. Help me out
/*right click disable*/
/*$(function() {
$(this).bind("contextmenu", function(e) {
e.preventDefault();
});
});*/
$('.nav1', this).hide();
//drop down -logout
$(document).ready(function() {
$(".account").click(function() {
var X = $(this).attr('id');
if (X == 1) {
$(".submenu").hide();
$(this).attr('id', '0');
} else {
$(".submenu").show();
$(this).attr('id', '1');
}
});
//Mouse click on sub menu
$(".submenu").mouseup(function() {
return false
});
//Mouse click on my account link
$(".account").mouseup(function() {
return false
});
//Document Click
$(document).mouseup(function() {
$(".submenu").hide();
$(".account").attr('id', '');
});
});
/* drop down for sidebar*/
$(document).ready(function() {

z-index of content div is wrong
use this styling for content and it will work for you
.content {
border: 1px solid black;
position: absolute;
left: 37%;
top: 220px;
bottom: 0;
width: 75%;
float: left;
z-index: 222222;
height: 100%;
padding: 12px;
}
and if you want that your form div should be beside the
left menu div. than you have to try something else.
