Javascript help: "slide-revealing" menu

Current setup (plain HTML/CSS):
I've currently got this plain HTML/CSS setup, which is basically using a checkbox with no opacity, with labels acting as buttons (which they in fact are not).

Goal:
My goal is for the menu to act in the exact same way, when clicking the labels .menulabel.open and .menuLabel.close, but using javascript instead of plain HTML/CSS.
I would change these current labels to a-tags or p-tags and using onClick-functions, when I get the javascript working.
Like linked at the top of the thread, this is my goal, but using javascript to make it react, and not using a plain checkbox:
https://i.imgur.com/ha3NL0V.mp4
What have I tried so far?
Besides the plain HTML/CSS-solution I have tried setting up, which I wouldn't argue is the right way to make the menu, I have also tried setting this script up in my HTML-document, inwhich does not seem to work as I want it to:
function openNav() {
document.getElementsByClassName("menuTransition").style.left = "100%";
document.getElementsByClassName("menuBox").style.left = "0";
}
function closeNav() {
document.getElementsByClassName("menuTransition").style.left = "-200%";
document.getElementsByClassName("menuBox").style.left = "-100%";
}
(the javascript was supposed to just style the two elements when clicking on one of the a-tags the exact same way the CSS reacts, when checking the checkbox and "activating" the menu)
<div class="nav">
<a class="menuLabel open" onClick="openNav()">Menu</a>
<div class="nav menuBox transitionBox menuTransition"></div>
<div class="nav menuBox BG">
<a class="menuLabel close" onClick="closeNav()">Close</a>
<nav>
<ul>
<li><a>Option 1</a></li>
<li><a>Option 2</a></li>
<li><a>Option 3</a></li>
</ul>
</nav>
</div>
</div>
(basically the same HTML as above, just removing the labels and replacing them with a-tags)

You can use a single class and toggle that class on the click of a button, something like this:
function myFunction() {
var element = document.getElementById("myDIV");
element.classList.toggle("mystyle");
}
.mystyle {
width: 100%;
padding: 25px;
background-color: coral;
color: white;
font-size: 25px;
box-sizing: border-box;
}
<button onclick="myFunction()">Try it</button>
<div id="myDIV">
This is a DIV element.
</div>

document.getElementsByClassName("menuBox") return an array object .
you need to add the index , such as document.getElementsByClassName("menuBox")[0]

Incorrect work of the desktop and adaptive menu when hovering and clicking

I want to make an adaptive menu. The problem now is that in the desktop version, when you click on a menu item and its sub-items, it closes, and should only work while I am hovering over it. And in the mobile version with an adaptive less than 520px, it also closes when you click on a sub-menu item, and this is bad.
I need hover to work only in desktop version. Also I need a menu to not get closed after the click on the sub-items.
That also goes for mobile version.

$(this).children('.drop__down-list').slideToggle();

I hope this answer helps you!
#media (min-width: 520px){
.drop__down-menu:hover .drop__down-list {

I think you should adapt CSS style for mobile first.
then add #media (min-width: x) for large devices not inversely

Links to change colour with css not working properly

I have some code for which I am trying to make a navbar. I have links in the code and I changed them when the page is scrolled up a little. I change the colours ok but cant change on hover to stay permanent? I seem to have tried everything but its like its resetting my css all the time. It works fine with the links but cant seem to change on hover colour to stay the same.

I think the problem is how you are trying to set the css properties.
$(".nav-big a:link") selects the actual elements in the DOM tree, nit the corresponding rule in your .css file. Then, when you call ".css("property", "value")" on those elements, you effectively change their element.style property, which is equivalent to setting that property inline (i.e. `).
Since the specificity of inline styles is higher that that of styles defined in a .css file, your :hover rule in a .css file will not be applied anymore.
There isn't really a way to edit you .css files from either JavaScript or JQuery (which is still just a JavaScript library), so what you should do instead is dynamically add and remove classes as described here.
As a side note, you honestly don't need jQuery for such tasks in 2018. It has its uses, but those are all either advanced or obsolete. Loading a external library bloats your page and is overall frowned upon. .ready can be replaced by just placing your <script> tag at the end of the <body>, and others methods now have direct js counterparts. Please consider switching to native js especially if you are still learning the language.

Javascript - Move active link to top of navigation if window-width <= 800px

I have a responsive navigation which is fixed at the top and goes from horizontal to vertical if screensize is <=800 px wide.
Now I'm trying to move the currently active link to the top of the navigation if the screen size is <=800 px wide, but I can't seem to find a way.
I tried Javascript but it won't keep the currently active link at the top since the page refreshes or changes when a link is clicked.
I tried to put the loop in an if-statement but that doesn't work, so I removed the if-statement.
I would really appreciate it if someone could help me solve this problem.
Here's the Javascript:
/*------------------------move active link to top------------------------*/
function moveLink(){
var width = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
var list = document.getElementById('nav').childNodes;
for (var i = 0; i < list.length; i++) {
list[i].addEventListener('click',function()
{nav.insertBefore(this, nav.childNodes[0])});
}
}
Here's the navigation html:
<nav>
<ul id="nav" class="topNav">
<li><a onclick="moveLink()" href="/">Placeholder1</a></li>
<li><a onclick="moveLink()" href="Placeholder1.html">Placeholder1</a></li>
<li><a onclick="moveLink()" href="Placeholder1.html">Placeholder1</a></li>
<li><a onclick="moveLink()" class="active" href="licenses.html">Placeholder1 / FAQ</a></li>
<li><a onclick="moveLink()" href="Placeholder1.html">Placeholder1</a></li>
<li><a onclick="moveLink()" href="contact.php">Placeholder1</a></li>
<li class="icon"><a href="javascript:void(0);" onclick="myFunction()">
<img alt="open menu" src="graphics/menu.png" style="height: 30px; width: 30px;"></a>
</li>
</ul>
I have two stylesheets and the menu opens and closes via Javascript.
Here's my mobile css:
/*------------------------navigation------------------------*/
.topNav {
z-index: 1;
list-style-type: none;
margin: 0 auto;
padding: 0;
overflow: hidden;
position: fixed;
top: 0;
width: 100%;
font-size: 0px;
background-color: rgba(0,0,0,0.8);
box-shadow: 0px 0px 8px 0px rgba(0,0,0,0.75);
}
.topNav li {
display: inline;
}

font-size: 12px;
display: inline-block;
color: #fff;
text-decoration: none;
transition: color 0.2s ease-in-out;
line-height: 38px;
padding: 0px 0px 0px 20px;
}
.topNav li a:hover {
color: #777;
}
.topNav li a.active {
color: #999;
}
/*------------------------responsive navigation closed------------------------*/
.topNav li:not(:first-child) {
display: none;
}
.topNav li.icon {
float: right;
display: inline-block;
height: 38px;
vertical-align: middle;
transition: opacity 0.2s ease-in-out;
margin: 4px 5px 0px 0px;
width: 30px;
height: 30px;
padding-right: 20px;
}
.icon:hover {
opacity: 0.5;
}
/*------------------------responsive navigation opened------------------------*/
.topNav.responsive {
position: fixed;
top: 0px;
}
.topNav.responsive li.icon {
margin: 0 0 0 0;
position: absolute;
top: 4px;
right: 25px;
width: 30px;
height: 30px;
padding-right: 0px;
z-index: 1;
}
.topNav.responsive li.icon:hover {
opacity: 0.5;
}
.topNav.responsive li {
float: none;
display: inline;
}
.topNav.responsive li a {

}
thanks in advance,

I think you could do this just using CSS using flexbox and order property.
#media (max-width: 800px) {
nav ul {
display: flex;
flex-direction: column;
}
.active {
order: -1;
}
}
order: -1 ensures that the list item will move to the top of the column.
I moved the class active to the li, instead of the a, to make this work a little easier.

CSS horizontal submenu

I'm working on the navigation bar for a website and currently the main menu is complete. However, the "Services" and "Products" buttons need to each have their own sub-menu. The sub-menu should normally be hidden from view and appears when the user mouse-overs on the respective button.
Here is a fiddle with the desired result. Obviously, I'd rather not use any javascript if possible.
The idea I had initially was to have sub-menu have position: absolute with a z-index value lower than that of the main-menu, so that it can slide underneath the main-menu. However, doing so messes up with the width if I give it width: 100% and since my site is responsive, I avoid static widths.
I also tried doing with relative positioning, but that doesn't work either.
Another thing I don't like with that approach is that the markup for the main menu and sub-menu get split. Is it possible to get the above result, but with this markup?
<nav>
<ul class="nav">
<li role="presentation" class="active">Home</li>
<li role="presentation">Services
<ul>
<li role="presentation">Link 1
<li role="presentation">Link 2
</ul>
</li>
<li role="presentation">Products
<ul>
<li role="presentation">Link 3
<li role="presentation">Link 4
</ul>
</li>
<li role="presentation">About</li>
<li role="presentation">Contact</li>
</ul>
</nav>
Here is my code:

If you only need the submenu to mimic the one in the example, without using jQuery, using the second chunk of HTML with the CSS you supplied you could do:
nav:hover~ul {
top: 0px;
}
This shows the next ul element, in this case the subnav, whenever the nav is hovered over ("~" selector means select the ul element preceded by nav:hover).
However, if you want to do something more dynamic... id suggest just using JS/jQuery as well
