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.

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:

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'm practicing Bootstrap, and i'm working on Dropdowns. But there is something that is wrong and i don't know what it is. When i click on Dropdown button button, it doesn't display anything.

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

I have a bootstrap code for the search bar with a dropdown list but I want to display the option upon selection one from the dropdown list. Currently, it shows "All" and even you click on the dropdown and select any of the options it does not work. Anyone on it using JavaScript or jQuery to make it work

You could simple add click event on
dropdown-item
see below
$('.dropdown-menu .dropdown-item').click(function(){
var value = $(this).text();
console.log(value)
// Update the value and show it to the user
$(this).parent().parent().find(".dropdown-toggle").html(value);
});

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
for more informations about bootstrap dropdown, I suggest you this site (with working examples) :

Try with data-placement="top" which helps you out
The Popover Plugin
