I am trying to create a dropdown using Bootstrap with several options but when I click the button nothing comes down to select the option. Not sure what is going on.

Use the data-bs-toggle attribute instead of the data-toggle attribute.

my entire code is below, I do not have a main.js file yet. Just trying to get the dropdown menu to work but regardless of what I press the dropdown menu will not drop.
Here is my code:

<div class="dropdown-menu" aria-labelledby="navbarDropdown">

Thanks!
You Should Import Bootstrap using CDNs
and data-bs-toggle="dropdown" should be present in Button which opens dropdown

I guess you need to link ##bootstrap. min. js## file in your script src.
I can't get my bootstrap navbar to work correctly, when I hit the button it doesn't open, I have placed in every possible way the call to the bootstrap files and there is no way. I can't get it.

As I can see you import all the libraries and everything but you haven't wrote code for Navbar you only write content? how it will work.
Check this it will work for you.

You need to add javascript with jquery and popper js. Here is full example:

you have to include a compatible version of popper at the head of your document,
check the snippet

When I select an option from the dropdown menu, the values are changed but the dropdown menu disappears both visually and in the source code.
Thank you in advance for your help !
You need to link bootstrap at your project

I'm using bootstrap for the first time. My question is about dropdown menu.
When the dropdown button is clicked, the dropdown menu is open. After clicking one dropdown item, the dropdown menu is closed. Clicking anywhere in the window closes the dropdown menu too.
The question is:
I want to make the dropdown menu not to be closed when clicking the dropdown menu itself, because I want to nest another dropdown menu in it.
