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

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

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">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>

A possible reason is that you might be missing the functionality coming from JavaScript Bootstrap modules.
Try to add JS imports:

I'm learning to use Bootstrap and neither the Toggler nor the Dropdown expand, I honestly don't know if I'm doing something wrong

you have to import bootstrap.js file also to make togglers and dropdowns, work,

I am a CSS beginner and I want to center Bootstrap navbar horizontally on the page (that is, the navbar itself extends over the width of the page, but the elements in it should be center-aligned with respect to the navbar). How can I do this?

Whereas in my CSS file styles.css I try to center the navbar (but it remains fixed in the initial position):
.navbar {
text-align: center;
}
How can I solve the problem? Thanks in advance.
To center your navbar content, as justify-content-lg-center to your container to use flex to center everything, and add flex-lg-grow-0 to your navbar-collapse div so that it doesn’t grow (normally, that div grows to take up the available space, pushing the search form to the right).
Some of your attributes had a space in them like data-bs- target which won’t work correctly. Running your code through the W3 Validator one in a while is a good way to be sure there aren’t any typos.

I used Stackoverflow's snippet tool as it's a handy way to see the code in operation.
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).
