Twitter bootstrap v4: Vertically aligning breadcrumb element with navbar content - html

I have the below code snippet where in my navbar I have tried to include a breadcrumb with dropdown elements. I am trying to align the breadcrumb with the other elements of my navbar.
Please note: The below code snippet loads in mobile viewport which is fine - however, in col-lg and larger, the breadcrump element isn't vertically aligned with the other elements (i.e. navbar-brand and form-inline).

It has the drop down menu included.
The Dropdown for Bootstrap needs a Script-Dependency. For Bootstrap-5 the JS-Bundle is:

Bootstrap dropdown menu fails

Im new using bootstrap and Im having two big problems:
1. Im trying to include a dropdown section in the menu but it doesnt work at all.
2. When the screen is small it shows the button menu but it doesnt work too.
This is the code that I rescued from a website so it supposed to work perfectly, I dont know if it is a library mistake or that im doing the rows and cols wrong:
<div class="row menu" >
<header class="barra">
<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">

</div>
</nav>
</header>
</div>
A possible reason is that you might be missing the functionality coming from JavaScript Bootstrap modules.
Try to add JS imports:

How can i solve this problem?
Thanks
There's no reason to use popper.js, bootstrap.min.js and bootstrap.bundle.min.js
Just use bootstrap.bundle.min.js alone

I have copied their example on the bootstrap documentation site where possible.
I want to get the second <ul> pushed to the right so am using mr-auto as they do in their example however it's not working for me like it is in the example, I don't understand why. I even tried adding the class d-flex to the #navbarMain div but still no luck.
Even running through the values in the inspector shows everything the same as in the example as far as I can see.
Can someone tell me why this isn't working?

Found the issue, it was where I had used a container to constrain the nav elements:
<nav class="navbar bg-secondary navbar-dark">
<div class="container">
<nav class="navbar navbar-expand-lg">
You can have nested nav's but shouldn't have nested navbar classes, removing the additional <nav class="navbar"> made everything work:

Increase the size of the bootstrap nav bar

How do i increase the size of the Bootstrap nav bar so that it takes up the entire screen? Right now it only takes half the screen in desktop view however it does work fine with mobile optimization

</div>
</nav>
</div>
</body>
you will see it in bigger screen
1. add css to body width:100%;
2. remove the unnecessary </div> (after </nav>)
maybe you should add media-query:
#media only screen and (max-width: 480px) {
body{
width:100%;
}
}
but It works fine (without media-query):
body{
width:100%;
}
