JS
$('.dropdown-menu').on("click.bs.dropdown", function (e) { e.stopPropagation(); e.preventDefault(); });
Is there possible solution ?
The simplest way is to wrap it inside a form since the form will prevent the Dropdown from closing on click...
<nav>
...
<li class="nav-item dropdown">
<form>
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown">
Dropdown link
</a>
<div class="dropdown-menu">
....
</div>
</form>
</li>
...
</nav>

The other method is using jQuery to like this:
$('.dropdown-menu .nav-tabs .nav-link').on("click.bs.dropdown", function (e) {
$(this).tab('show');
e.stopPropagation();
});

Intro
I'm using Bootstrap 5 (bundled with webpack 5), with his grid system and the collapse function to create the home page to this site, that has 2 sidebars that collapse into a topbar.
When we get to a mobile format the navs collapse and the columns containing them stack up leaving the 3rd col with the logo at the bottom without overflowing the parent.
Look at my 100% accurate ms paint graphics to understand better
Issue
When we show the collapsed navs, the columns containing them push the 3rd col with the logo out of the row and the container-fluid containing it.
Question
How can i make the navs expanding without pushing the logo? (to clarify the logo needs to stay below the navs

I solved this by making the logo a background-image and merging the collapsible elements under the same parent with js.
There's probably a better solution though and maybe one that let you have the image at a block/inline level.
I would prefer a strictly JavaScript way of doing this if possible. Not really wanting to introduce a JavaScript framework into my project.
Layout:
./index.html
./about.html
./crew.html
./flights.html
./events.html
I want every page to have the same navbar such that I don't have to repeat myself and fix every page every time the order of the links change.
Here's my example navbar:
<nav class="navbar navbar-expand-xl navbar-light">
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#toggleMobileMenu" aria-controls="toggleMobileMenu" aria-expanded="true" aria-label="Toggle Navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse show" id="toggleMobileMenu">
<ul class="navbar-nav mx-auto">
<li class="nav-item text-center">
<a class="nav-link" href="index.html">Home</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="about.html">About</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="crew.html">Crew</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="flights.html">Flights</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="events.html">Events</a>
</li>
</ul>
</div>
</nav>
Depending on what kind of browser support you need you could use a template literal (back ticks) to define your navigation. Then use insertAdjacentHTML to place it where you need it on all your html pages. If your page is fairly simple you could just insert the nav after begin on the body tag.
const navigation = `
<nav class="navbar navbar-expand-xl navbar-light">
<button
class="navbar-toggler"
type="button"
data-bs-toggle="collapse"
data-bs-target="#toggleMobileMenu"
aria-controls="toggleMobileMenu"
aria-expanded="true"
aria-label="Toggle Navigation"
>
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse show" id="toggleMobileMenu">
<ul class="navbar-nav mx-auto">
<li class="nav-item text-center">
<a class="nav-link" href="index.html">Home</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="about.html">About</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="crew.html">Crew</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="flights.html">Flights</a>
</li>
<li class="nav-item text-center">
<a class="nav-link" href="events.html">Events</a>
</li>
</ul>
</div>
</nav>
`
document.getElementById("nav-container").insertAdjacentHTML('afterbegin', navigation);
<div id="nav-container"></div>
I get this Dev Console error message "Cannot read property 'children of null" while I'm trying to use a dropdown button with Nav Tabs in Navbar Component.
when I click on the dropdown item to display nav-link in navbar I get this Dev Console error message "Cannot read property 'children of null"

Caveat: This is not the intended use of Bootstrap Tabs and Dropdowns. Dropdowns aren't designed used to toggle Tabs, and Tabs aren't meant to be used in the Navbar.
This doesn't describe why it's happening, but if you would like a solution.
Remove some of the attributes associated with the dropdown list item buttons (see below for example). Depending on what you want to do, you can either set up JavaScript event listeners for those buttons. Or you can change the buttons to anchor tags and navigate to a different page.
<div id="nav-tab" class="dropdown" role="tablist">
<button type="button" id="dropdownEx" class="btn btn-dark dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">Select Item</button>
<ul class="dropdown-menu" aria-labelledby="dropdownEx">
<li>
<button type="button" role="tab" id="nav-example-1-tab" class="dropdown-item active">
Example 01
</button>
</li>
<li>
<button type="button" role="tab" id="nav-example-2-tab" class="dropdown-item">
Example 02
</button>
</li>
</ul>
</div>
"Leaf" menu items like Example 1 and Example 2 should not contain data-bs-toggle="dropdown"
I'm creating a dropdown accordion style in bootstrap 4 and found this useful solution using JavaScript in stack overflow (Twitter Bootstrap: How to create a dropdown button with an accordion inside it?). I modified the script to suit my website navigation style but I got stuck on how to make the JavaScript find not only ID: accordion but also ID: accordion1 and so on. Thus, when I navigate out of the menu, the accordion that open will automatically hide. Currently, the script can only hide the first panel which is ID: accordion. For this project, I can't use form tag as described in Bootstrap 4: How to create a dropdown menu with an accordion inside it?. Sample in Bootply
Also, how do I make the accordion panels open in multiples.

$('.dropdown-accordion').on('show.bs.dropdown', function(event) {

accordion.find('.show').collapse('hide');

According to your script, you really are just hiding the div with id='accordion'. If you want to hide them all, you have to know the nr of accordions you have, and iterate through all of them.
<script>
$('.dropdown-accordion').on('show.bs.dropdown', function(event) {
for(var i = 0; i < nrAccordions; i++)
{
var accordion = $(this).find($(this).data('accordion'+i));
accordion.find('.show').collapse('hide');
}
});

On desktop code works properly when downward scroll is detected navbar is hidden (top:100px) and when upward scroll is detected navbar will be display but In mobile device When I clicked on hamburger menu it collapse but also hiding logo and hamberger section.
