$(document).ready firing before the DOM is loaded - javascript

I'm working on a nav bar using Bootstrap 4.0. I have a pillbox nav bar and I wrote a javascript function to automatically detect the current page and add the active class to the right pillbox. I set the function to run when the DOM is ready but it runs before any of the HTML in the BODY is loaded. Essentially the script fails to find any elements with the 'nav-link' class at runtime and does nothing. If I add the async attribute to the script however, it works as expected.
function main () {
$nav = $('nav-link');
$('.nav-link').each( function () {
var currentPage = location.href.split("/").slice(-1);
var currentLink = $(this).attr('href').slice(2);
console.log(currentPage);
console.log(currentLink);
if (currentLink == currentPage) {
$(this).addClass('active');
} else {
$(this).removeClass('active');
}
});
}
$(document).ready(main());
This is my HTML file.

Using $(document).ready(main()) calls the main() function then and there. You should be using $(document).ready(main)
function main() {
$nav = $('nav-link');
$('.nav-link').each(function() {
var currentPage = location.href.split("/").slice(-1);
var currentLink = $(this).attr('href').slice(2);
console.log(currentPage);
console.log(currentLink);
if (currentLink == currentPage) {
$(this).addClass('active');
} else {
$(this).removeClass('active');
}
});
}
$(document).ready(main);

You should just use $(main), which is a shorthand for $(document).ready(main).
Your syntax is executing the main function instead of passing it, that's why you experience your problem.

Can I get example with worked dropdown on bootstrap 5.3 ?
I think I have attached all the necessary libraries for the dropdown menu to work ?

You have to add Bootstrap's JavaScript as well:
// Add this line before the closing </body> tag
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.3.0-alpha1/dist/js/bootstrap.bundle.min.js" integrity="sha384-w76AqPfDkMBDXo30jS1Sgez6pr3x5MlQ1ZAGC+nuZB+EYdgRZgiwxhTBTkF7CXvN" crossorigin="anonymous"></script>
i.e.
<div id="map">
<!-- Load map -->
<script src="./js/leaflet.js"></script>
</div>
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.3.0-alpha1/dist/js/bootstrap.bundle.min.js" integrity="sha384-w76AqPfDkMBDXo30jS1Sgez6pr3x5MlQ1ZAGC+nuZB+EYdgRZgiwxhTBTkF7CXvN" crossorigin="anonymous"></script>
</body>
</html>

You have included BOOTSTRAP twice!
delete this row from your head tag
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.3.0-alpha1/dist/js/bootstrap.min.js" integrity="sha384-mQ93GR66B00ZXjt0YO5KlohRA5SY2XofN4zfuZxLkoj1gXtW8ANNCe9d5Y3eG5eD" crossorigin="anonymous"></script>
Working example without it: https://jsfiddle.net/MarinHTML/8kscdbn9/11/
------EDIT----- depricated old answer: ---
you're gonna need some JS to do the job here, because what you did is NEST a dropdown into another dropdown. Not sure if possible by simple bootstrap means. You can, but it must be on hover, and I presume you don't want that.
Here is a quick example of what I think you want:
https://jsfiddle.net/MarinHTML/t7zmqcd9/
And here is the JS to use it:
let dds = document.querySelectorAll('.dropdown-toggle')
dds.forEach((dd)=>{
dd.addEventListener('click', function (e) {
var el = this.nextElementSibling
el.style.display = el.style.display==='block'?'none':'block'
})
})

Bootstrap provides you with several stackblitz links to check their templates, like this: https://stackblitz.com/run?file=index.html
Used on your code would be something like this:

How to initialize tooltip with popper.js and bootstrap

I am using bootstrap tooltip as explained # https://getbootstrap.com/docs/4.3/components/tooltips/
I have successfully created tooltip but tooltip is appearing un-formatted. I believe this is because the tooltip is not getting initialized. I have the code added as shown on the page below.Tried initialization code at different places on page as well.

This is NOT as per bootstrap recommendation (https://getbootstrap.com/docs/4.3/getting-started/introduction/#starter-template), but it works.
The fix came from code described # https://www.w3schools.com/bootstrap4/bootstrap_tooltip.asp

I suggest you to just use the bundle Popper + Bootstrap: bootstrap.bundle.min.js or bootstrap.bundle.js. That should bypass any problem you may have with correct file order initialization. I mean, whether you place your files in header and/or body (in my case, it worked after placing the bundle at the bottom of the body, before closing the body tag).
https://getbootstrap.com/docs/5.1/components/tooltips/#overview
And remember to initialize the tooltips correctly from your local scripts:
https://getbootstrap.com/docs/5.1/components/tooltips/#example-enable-tooltips-everywhere
This Vanila JS code should be enough for that:
var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
tooltipTriggerList.map(function (tooltipTriggerEl) {
return new bootstrap.Tooltip(tooltipTriggerEl)
})
By the way, I placed this code after the aforementioned bundle.

Use grid inside collapse body

In the below snippet I have a collapse which shows if you hover over the second nav-link item. Now I want to use the Grid system inside this collapse but I can't seem to make it work.
What does not work?
The columns just display underneath one another.
How do I use the grid system inside the collapse body?
$(".menu1").hover(
function() {
$('.panel').collapse('show');
}, function() {
$('.panel').collapse('hide');
}
);

Bootstrap Navbar Dropdown Not Working in Browser, Codepen okay

I have a document with a navbar whose dropdown menu just won't work. It works in my codepen, but not through my text-editor(Sublime). I have searched all over for a solution, so here I am.
I have tried:
-Bootstrap Docs
-Making sure jQuery script is before Boostrap script
-Triple checking my closures
-Lots of searching Google and StackOverflow.
-Adding this code:
<script>
$("document").ready(function() {
$(".dropdown").dropdown();
});
</script>
Here's what I believe to be the relevant code. Any insights to my mistake will be greatly appreciated.

The problem is that you use two different versions of bootstrap of bootstrap. In your header you use the CSS of Bootstrap 4.0.0-alpha.6 and on the end of your body you have the JavaScript of version 3.3.7. You can either use one or the other but not both together.
This code works for me:

well you have extra </li> after <a class = "dropdown-item" href = "#concrete">Concrete</a> reomove it. and in your script dropdown-toggle should be pointed
WRONG
$("document").ready(function() {
$(".dropdown").dropdown();
});
remove "" in document and .dropdown it should be written like this
CORRECT
$(document).ready(function() {
$(".dropdown-toggle").dropdown();
});

Bootstrap is a ready framework with features like grid system, rows, ready js menus and more.
There's an explanation of how it works:
http://twitter.github.com/bootstrap/javascript.html#dropdowns
It doesn't work for me.
Yes, my src links correctly to the JS files.

your missing the body in your html.
put your script at the bottom of the page or after ready:
<script type="text/javascript">
$(function(){
$('.dropdown-toggle').dropdown();
});
</script>
demo: http://jsfiddle.net/rLL75/
EDIT:
use a newer version of jquery.

<header>
<div class="navbar navbar-static header">
<div class="navbar-inner container">
<ul class="nav" role="navigation">
<li class="brand"><span style="color: #bde2e1;">Home</span></li>

<a class="dropdown-toggle" id="drop4" role="button" data-toggle="dropdown" href="#">Dropdown <b class="caret"></b></a>
