How to select certain elements in a group of elements with the same class tag using jquery

I am trying this sidebar of a dashboard and it looks like this
The top child or the one with the brighter green color on it has a class active_link which basically tells you that you are in this part of the dashboard. So the idea is that I want the class active link to be added to the certain element that I have clicked upon while the rest who are not clicked don't have (Meaning that if the element already have the active_link but it is not the one that I have clicked upon then the class will be removed however if it does not have the active_link class and it is the one I clicked it will be added to that certain element). However, I have a problem.I tried running this code:
$(function(){
$(".sidebar_link").click(function(){
$(".sidebar_link").each(function(index){
if($(this).data('clicked', true)){
if($(this).hasClass('active_link') == false){
$(this).addClass('active_link');
}
}else{
if($(this).hasClass('active_link')){
$(this).removeClass('active_link');
}
}
});
});
})
And this is what happened:
Which what I could tell is just a disaster, any tips? Thank you in advance! Here is the HTML
<div class="sidebar_menu">
<div class="sidebar_link active_link">
<i class="fa fa-home"></i>
Dashboard
</div>
<h2>MANAGE</h2>
<div class="sidebar_link">
<i class="fa fa-building-o"></i>
See Admin Notif
</div>
<div class="sidebar_link">
<i class="fa fa-wrench"></i>
Update Profile
</div>
<div class="sidebar_link">
<i class="fa fa-archive"></i>

</div>
<div class="sidebar_link">
<i class="fa fa-handshake-o"></i>
Connect
</div>
<div class="sidebar_logout">
<i class="fa fa-power-off"></i>
Log out
</div>
</div>

You can simply use $(".sidebar_link").not($(this)).removeClass("active_link") to remove class from other sidebar which is not been clicked by user.
Demo Code :
$(".sidebar_link").click(function() {
$(".sidebar_link").not($(this)).removeClass("active_link")
$(this).toggleClass('active_link');
});
.active_link {
background-color: green
}

Make active block not hidden after refresh

Well, I am making a simple left panel menu. What I want to do is to make sub-menu visible even after refresh when the category is active.
Example:
-Users
-Dashboard
-Blog
-----articles
-----new article
I am on articles si I can see entire submenu even after refreshing of the website.
I make it works this way.
Handlebars menu
<div class="blog-tab {{#if active.blog}}admin-panel-active-tab{{/if}}" id="blog-tab">
<a>
<i class="fas fa-pen"></i>Blog
<i class="fas fa-caret-down admin-panel-item-dropdown"></i>
</a>
</div>
<div id="blog-sub-tab" class="toggleable-tab">
<div class="sub-toggleable-tab">
<div class="{{#if active.posts}}admin-panel-active-tab{{/if}}"><i class="fas fa-circle"></i>Articles</div>
<div class="{{#if active.newPost}}admin-panel-active-tab{{/if}}"><i class="fas fa-circle"></i>Create new article</div>
</div>
</div>
<div class="eshop-tab {{#if active.eshop}}admin-panel-active-tab{{/if}}" id="eshop-tab">
<a><i class="fas fa-store"></i>Eshop
<i class="fas fa-caret-down admin-panel-item-dropdown"></i>
</a>
</div>
<div id="eshop-sub-tab" class="toggleable-tab">
<div class="sub-toggleable-tab">
<div class="{{#if active.eshopCatalog}}admin-panel-active-tab{{/if}}"><i class="fas fa-circle"></i>Catalog</div>
<div class="{{#if active.createNewProduct}}admin-panel-active-tab{{/if}}"><i
class="fas fa-circle"></i>Create new product</div>
<div class="{{#if active.eshopOrders}}admin-panel-active-tab{{/if}}"><i class="fas fa-circle"></i>Orders</div>
</div>
</div>
Handlebars make it scrolled.
{{#if active.blog}}
<script>$("#blog-sub-tab").slideToggle(0);</script>
{{/if}}
{{#if active.eshop}}
<script> $("#eshop-sub-tab").slideToggle(0);</script>
{{/if}}
I am passing to every subcategory active.blog or active.tab so it's easy.
But now I am using webpack and cant use jquery when its frontend rendered.
Yes, it can be fixed... But I am looking for any better way how to do it.
That can be done only in js(with jquery) without handlebars. Thank for any help.

How to add active and remove existing active class collapse on bootsrap 4

Someone please help me, how to add "active" class after "careers-menu-container" class and remove existing another active class when click button(a)?.
please check my code below!.
Thanks a lot off.
<div class="container" id="myCollapse">
<div class="col-sm-12 col-md-4 order-sm-1 order-md-1">
<div class="careers-menu-container careers-menu-container__img1">
<a data-toggle="collapse" href="#collapseExtension1" role="button" aria-expanded="false" aria-controls="collapseExtension">APPLY NOW <i class="fas fa-caret-right"></i>
</a>
</div>
</div>
<div class="collapse" id="collapseExtension1" data-parent="#myCollapse">
<p>lorem ipsum</p>
</div>
<div class="col-sm-12 col-md-4 order-sm-3 order-md-2">
<div class="careers-menu-container careers-menu-container__img1">
<a data-toggle="collapse" href="#collapseExtension2" role="button" aria-expanded="false" aria-controls="collapseExtension">APPLY NOW <i class="fas fa-caret-right"></i>
</a>
</div>
</div>
<div class="collapse" id="collapseExtension2" data-parent="#myCollapse">
<p>lorem ipsum</p>
</div>
</div>
$(".collapse.show").each(function(){
// show active class here
});
// Toggle plus minus icon on show hide of collapse element
$(".collapse").on('show.bs.collapse', function(){
// show active class and remove another active class
}).on('hide.bs.collapse', function(){
// remove class here and show another active class
});

You can access .careers-menu-container via .collapse using .parent():
$(".collapse").on('show.bs.collapse', function(){
$(this).parent().addClass('active')
}).on('hide.bs.collapse', function(){
$(this).parent().removeClass('active')
});

JS Hide header elements and resize navigation bar on scroll

I have a large header section for a website that is split into three sections; social links, logo, and then the navigation bar. I am trying to figure out how I can hide the top two elements and resize the navigation bar and have it fixed when the user scrolls past it.
The nav bar currently just holds a link that will open up a separate side menu that holds all of the actual page navigation.
https://jsfiddle.net/cxekxrxy/2/
<header>
<!-- social links -->
<div id="social" class="social-header">
<div class="container">
<div class="row">
<ul>
<li class="social-icon"><i class="fa fa-facebook-official" aria-hidden="true"></i></li>
<li class="social-icon"><i class="fa fa-twitter-square" aria-hidden="true"></i></li>
<li class="social-icon"><i class="fa fa-instagram" aria-hidden="true"></i></li>
<li class="social-icon"><i class="fa fa-linkedin-square" aria-hidden="true"></i></li>
</ul>
</div>
</div>
</div>
<!-- logo -->
<div id="logo" class="logo-header">
<div class="container">
<div class="row">
<h1 class="logo-main">Main Header</h1>
<h2 class="logo-sub">Sub Header</h2>
</div>
</div>
</div>
<!-- Navigation -->
<div id="header" class="main-header">
<div class="container">
<div id="bars"><span class="glyphicon glyphicon-menu-hamburger text-right" id="nav-bars" style="font-size:25px; cursor:pointer" onclick="openNav()"></span></div>
</div>
<!-- nav links (hidden until <span> is pressed) -->
<div id="main-nav" class="side-nav">
×
<span class="glyphicon glyphicon-home"> Home</span>
<span class="glyphicon glyphicon-user"> About</span>
<span class="glyphicon glyphicon-picture"> Portfolio</span>
<span class="glyphicon glyphicon-envelope"> Contact</span>
</div>
</div>
</header>

Hiding and showing fields via Javascript based on the type of the category the results item has

I have a dynamic list of properties on a search results page, the problem I am having on each individual search result is that if it is a certain property type i.e. Land it does not need the bedrooms and bathrooms fields within that search result to show, but if it is a Villa, the fields would show.
I would need to show and hide fields on the page load in JS like my example above on each individual search result as if I do a general JS function for Land hiding the div classes for bedrooms and bathrooms, there could also be a Villa on the page needing those fields.
If anyone could help with some JS to help me solve this issue above, it would be much appreciated!
Heres some of the Html Results below, you will see there are multiple property types, so different fields should be show/hidden

I'm just gonna go ahead and make up my own HTML structure to demonstrate the simple if/else statement you would make with jQuery.
function hideFields() {
$(".result").each( function() {
if ( $(this).hasClass("land") ) {
$(this).children(".bedroom").hide();
$(this).children(".bathroom").hide();
}
else if ( $(this).hasClass("villa") ) {
$(this).children(".land-area").hide();
}
});
}
hideFields();
span {
display:block;
border:1px solid black;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<div class="result villa"><b>Villa</b><br>
<span class="bedroom">Bedroom</span>
<span class="bathroom">Bathroom</span>
<span class="location">Location</span>
<span class="land-area">Land-area</span>
</div>
<br>
<div class="result land"><b>Land</b><br>
<span class="bedroom">Bedroom</span>
<span class="bathroom">Bathroom</span>
<span class="location">Location</span>
<span class="land-area">Land-area</span>
</div>
Your HTML seems confusing for multiple reasons, which you can easily fix to use this method:
1) sppools, spbaths, spbeds should indeed be classes rather than IDs. This is due to IDs being unique identifiers - they should hence not appear more than once on each page, whereas classes identify a "type" (class) of item, which may appear multiple times. Multiple instances of the same ID will mess with your CSS and JS.
2) There is no clear definition within each result of what type of result this is (or I can't seem to find it, at least?).
Words like "villa" or "house" indeed appear in the title-tag, but having to search within these is an inefficient way of performing the action.
Instead, make your code show the type of content as a class on each li-item or the initial div-item.
