Toggle 'display:none' with JavaScript after transition?

I want to implement a dropdown menu for mobile devices with animation so when the transition ends, it needs to be display:none. Here's what I've done:
const menuButton = document.querySelector('.menuButton')
const navMenu = document.querySelector('.nav')
function menuToggle() {
if (navMenu.classList.contains('navDisplay')) {
navMenu.classList.remove('navShow')
setTimeout(() => {
navMenu.classList.remove('navDisplay')
}, 300)
} else {
navMenu.classList.add('navDisplay')
setTimeout(() => {
navMenu.classList.add('navShow')
}, 0)
}
}
menuButton.addEventListener('click', menuToggle)

}

}

}

}
.menuButton {
display: none;

}
nav div ul {
text-align: center;
flex-direction: column;
margin-top: 50px;
overflow: hidden;
}
nav div ul li {
margin: 20px 0;
}
nav {
flex-direction: column;
}
.nav {
display: none;
box-sizing: border-box;
width: 100%;
overflow: hidden;

</ul>
</div>
</nav>
</header>
So, the menu has display:none and height:0 by default. The click event listener triggers function that checks if menu is displayed or not and adds or removes respective classes (the display class removes after the transition ends with the help of timeout 400ms). Is there any more beautiful or less code solutions?

You are making it way more complex. You don't need to have a display:none and a height:0. height:0 with overflow:hidden will do the job. If you wanna show the links after the menu gets its height with a delay, you could use opacity. That and using the toggle function will make it as simple as this:
const menuButton = document.querySelector(".menuButton");
const navMenu = document.querySelector(".nav");
function menuToggle() {
navMenu.classList.toggle("navShow");
}
menuButton.addEventListener("click", menuToggle);

Problem with css animation: position relative and value for left doesn't work apparently together

Here's my problem:
I'm trying to animate a nav list (ul) and in my mind, I want to move it on click like that:
$('#top-nav-more').click(function() {
$('.hidden').toggleClass('hidden-click');
$(this).find('img').toggleClass('rotate');
});
/** Top Nav **/
#top-nav {
background: #e41a2e;
padding:0 !important;
display: inline-block;
/*height:40px;*/
}
.top-nav-wrapper{
max-width:1366px;
margin: 0 auto;
}
a.top-req-info{
position: absolute;
font-family: 'Daxline Light';
font-size: 0.80rem;
color: #FFF;
background: #cd1729;
padding: 10px 20px 11px 10px;
/* float: left; */
}
a.top-req-info:hover, #top-nav-book a:hover, .hidden a:hover {
text-decoration:none;
color: #821b31;
}
a.top-req-info:hover, #top-nav-book:hover {
background: #821b31;
color: white;
}
#top-nav-book:hover a {
color: white;
}
#top-nav-more a, #top-nav-no a, #top-nav-book a, .hidden a {
color: #FFF;
font-size: 0.80rem;
}
.rotate {
transform: rotate(180deg);
}
ul.top-nav-right{
list-style: none;
float: right;
display: inline;
margin: 7px 0;
}
ul.top-nav-right li{
display:inline;
padding: 8px 25px 8px;
}
li#top-nav-more{
background: #cd1729;
}
#top-nav-more img{
margin-right: 15px;
transition: 0.3s;
}
.hidden {
position: relative;
left: 321px;
display: none!important;
transition:all 1s linear;
}
.hidden-click {
transition:all 1s linear;
position: relative;
left: 0;
display: inline!important;
}
ul .hidden:first-child {
display: inline!important;
left: 0;
}
.search-bar input {
background-color: #821A31;
color: #ffff;
font-size: 35px;
border: 0;
margin: 0;
height: 76px;
width: 100%;
padding: 0 80px;
font-weight: 200;
display: none;
}
.search-bar input:focus, .search-bar input:focus{
outline: none;
}
.search-bar input.slide-down {
display: block;
}
.search-bar input::placeholder {
color: white;
}
.hover-bar {
background: #821A31!important;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!-- Top Navigation -- Red bar -->
<div id="top-nav" class="container-fluid">
<div class="top-nav-wrapper">
<ul class="top-nav-right">
<li class="hidden">Health Care</li>
<li class="hidden">My Account</li>
<li class="hidden">Student Portal</li>
<li id="top-nav-more">More</li>
<li id="top-nav-no">Phone number</li>
<li id="top-nav-book">Book a Tour</li>
</ul>
</div>
</div>
Essentially, when you click more, the bar will change the position from some certain pixels to the left to 0 pixels on the left.
I added the transition effect to do it smoothly but for some reason, the effect happens right away. So technically it works but it doesn't work as I wish.
Something has to be wrong on my css transition. I read that it is possible to animate the position, so it is not a problem of position, it has to be something different. I've already use the property transition somewhere else in my code, so I have no clue of what is wrong, any idea?

This might get you close. I imagine there might be more to the animation you're looking for. It's hard to manipulate elements that are set to display none. Visibility: hidden and position: absolute is an equivalent you can manipulate:
/** Top Nav **/
#top-nav {
background: #e41a2e;
padding:0 !important;
display: inline-block;
/*height:40px;*/
}
.top-nav-wrapper{
max-width:1366px;
margin: 0 auto;
}
a.top-req-info{
position: absolute;
font-family: 'Daxline Light';
font-size: 0.80rem;
color: #FFF;
background: #cd1729;
padding: 10px 20px 11px 10px;
/* float: left; */
}
a.top-req-info:hover, #top-nav-book a:hover, .hidden a:hover {
text-decoration:none;
color: #821b31;
}
a.top-req-info:hover, #top-nav-book:hover {
background: #821b31;
color: white;
}
#top-nav-book:hover a {
color: white;
}
#top-nav-more a, #top-nav-no a, #top-nav-book a, .hidden a {
color: #FFF;
font-size: 0.80rem;
}
.rotate {
transform: rotate(180deg);
}
ul.top-nav-right{
list-style: none;
float: right;
display: inline;
margin: 7px 0;
}
ul.top-nav-right li{
display:inline;
padding: 8px 25px 8px;
}
li#top-nav-more{
background: #cd1729;
}
#top-nav-more img{
margin-right: 15px;
transition: 0.3s;
}
.hidden {
position: absolute;
left: 321px;
visibility: hidden;
transition:all 1s linear;
}
.hidden-click {
transition:all 1s linear;
position: relative;
left: 0;
visibility: visible;
}
ul .hidden:first-child {
display: inline!important;
left: 0;
}
.search-bar input {
background-color: #821A31;
color: #ffff;
font-size: 35px;
border: 0;
margin: 0;
height: 76px;
width: 100%;
padding: 0 80px;
font-weight: 200;
display: none;
}
.search-bar input:focus, .search-bar input:focus{
outline: none;
}
.search-bar input.slide-down {
display: block;
}
.search-bar input::placeholder {
color: white;
}
.hover-bar {
background: #821A31!important;
}
Working/semi-working example:
https://jsfiddle.net/qLpfynks/

I believe the reason is because you are switching from display:none to display: inline. CSS cannot transition display and so it will show the "transition" immediately.
To fix this and still achieve the desired effect change it to
.hidden {
position: relative;
left: 321px;
display: inline!important;
opacity:0; /*makes it invisible*/
transition:all 1s linear;
/*transition:left 1s linear*/
}
.hidden-click {
transition:all 1s linear;
/*transition:left 1s linear*/
position: relative;
left: 0;
opacity: 1; /*makes it visible*/
display: inline!important;
}
Note that if you use the specificier all for your transition you will see a fade in and out animation. If you don't want this, specify only left (see commented CSS code)

Add/Remove class to get a menu to display

I started programming the mobile version of my nav menu earlier. I had to rework my #serviceNav to get it to work in a mobile setting. When doing this I changed my javascript from this:
/*$('#serviceClick').click( function () {
$('#serviceNav').addClass('activeSol');
});*/
$('[data-pop-close]').on('click', function(e) {
//var targeted_pop = $(this).attr('data-pop-close');
$('#serviceNav').removeClass('active');
$('body').css('overflow', 'auto');
e.preventDefault();
});
To this:
$('#serviceClick').click(function() {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
relative.addClass('activeSol').next('#serviceNav').slideDown();
//$('.infoTitles:before').addClass('opened');
} else {
relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
}
return false;
});
The issue that I am having now that I previously didn't with my javascript code is that now my desktop media query version of my #serviceNav is not displaying, however it does display and function in the mobile setting. The trigger for this menu is the menu item called "Solutions". You can see that in a media query over 640px that nothing happens, but 640px or less it applies the fadeDown function.
Does anyone see why this is not working for the larger version media query?
Here is a jsfiddle
Full code:
$('#mobile-button').on('click', function () {
$('#nav-pop').addClass('active');
$('html').addClass('is-navOpen');
});
/*$('#serviceClick').click( function () {
$('#serviceNav').addClass('activeSol');
});*/
$('#serviceClick').click(function() {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
relative.addClass('activeSol').next('#serviceNav').slideDown();
} else {
relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
}
return false;
});

There is a lot going on here and frankly, it's hard to decipher but I think "Nothing happens" is relative. When inspecting the element in dev console you can see the Javascript styling is being added appropriately. So something is happening, it's simply happening off screen because you've told it to. I think the culprit here, is the >640px positioning of your #serviceNav element is maintained at top: -40vh; That's a lot. When removing this value the button displays as follows:
Note: you will have to change some other things around as this displays it on page load. But you get the idea

Click function never reading else statement to remove class

I have been stuck on a sliding down menu, but have made some headway with it. I had to modify a lot to make it work for both desktop and mobile viewports. The only thing I am stuck on now is getting the menu to close in a < 640px viewport.
In my snippet and jsfiddle below there is a lot of code, but the only code that really matters to this question is the javascript below:
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});
Basically my else statement is now removing the class 'activeSol` and then sliding up the selection.
In the mobile viewport, after clicking on "Solutions" the menu expands, but when you click on "Solutions" again, nothing happens.
It seems as if the variable relative is never reading as the class appended to it, making the click function run else. I did a simple console.log and the else never runs. I tried changing the click function to a change, but then the menu never triggers.
Does anyone see what is causing my else statement to not removeClass from serviceNav and slideUp?
JSfiddle link to see in mobile viewport.
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});
$('[data-pop-close]').on('click', function(e) {
//var targeted_pop = $(this).attr('data-pop-close');
$('#serviceNav').removeClass('activeSol');
$('body').css('overflow', 'auto');
e.preventDefault();
});

var relative = $(this);
Is picking the serviceClick list item (li) and then you are checking
if (!relative.hasClass('activeSol')) {
but you never added the class to the li, instead you added it to the div #serviceNav.
I think changing
if (!relative.hasClass('activeSol')) {
to
if (!$('#serviceNav').hasClass('activeSol')) {
should work.

Your shouldn't check for $("#serviceClick") for class activeSol, should check on $("#serviceNav") instead.
if (!$('#serviceNav').hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}

relative doesn't have the class 'activeSol' and will never have it, in order to have it toggle the visibility of your menu, you should add and remove classes to it, like this:
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('opened')) { // if it's not opened
relative.addClass('opened'); // open it
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else { // if it's opened
relative.removeClass('opened'); // close it
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});

Add a fadeIn effect on toggleclass?

I want to add a fadeIn/Out effect on a toggle class when navigation is open and close. Somebody know how? I'm using the toggle class because of a responsive problem i had before when resizing part of the navigation disappeared.
FIDDLE example
nav ul.show {
display: block;
}
And for the javascript
$(function() {
$('.nav-btn').click(function(event) {
$('nav ul').toggleClass("show");
});
});

I prefer using css transitions these days over jquery animations. To me that appears more clear and easier to read, since logic and visualization are more separate. In the end the action is not the fading, but the change of state (or class in this case). The fading effect is a pure optic gimmick.
nav ul {
display: block;
opacity: 0;
transition: opacity 500ms;
}
nav ul.show {
opacity: 1;
}

Try this: Demo
// Show navigation //
$(function() {
$('.nav-btn').click(function(event) {
// alert();
if($('nav > ul').hasClass("show"))
{
// alert();
$('nav > ul').fadeOut(1000, function() {
$('nav > ul').removeClass('show');
});
} else {
//alert('no class');
$('nav > ul').fadeIn(1000, function() {
$('nav > ul').addClass('show');
});
}
});
});

Use fadeToggle() method in jquery
you can refer the other methods also here
Hope this helps

try this.
http://jsfiddle.net/wz8vc0yo/12/
$(function() {
$('.nav-btn').click(function(event) {
$('nav ul').fadeToggle("slow");
});
});

jquery:
$(#divID).toggleClass('yourClass').fadeOut('slow');
