Menu
I am facing a issue when trying to create a responsive menu or dropdown button with Bootstrap 5.Everything seems ok.The navigation icon & dropdown icon apears.But its not working.When I clicked the nav icon or dropdown button,no dropdown menu apears.
I want to specially mention that I also included the jquery file. But it didn't work. Can anyone please tell me what is happening here?
One last thing,I faced severel issues with some others bootstrap classes like mr-auto,ml-auto etc.Is it any bug or new classes come with bootstrap 5 for this kind of job?
Here is my code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Bootstrap</title>

<button

<span class="navbar-toggler-icon"></span>

<div class="navbar-collapse collapse" id="navbar" navbar>
<ul class="navbar-nav">

To create a collapsible navigation bar, use a button with class="navbar-toggler", data-toggle="collapse" and data-target="#thetarget" . Then wrap the navbar content (links, etc) inside a div element with class="collapse navbar-collapse" , followed by an id that matches the data-target of the button: "thetarget".
The navbar items can be aligned using flex utility. Use . justify-content-end class on collapse menu to justify items to the right.
Nature of connection between button and navbar: buttons show and hide another element via class changes: . collapse hides content Use a button with the data-target attribute and the data-toggle="collapse". The classes collapse and navbar-collapse are significant for the CSS.
Use the . navbar-text class to vertical align any elements inside the navbar that are not links (ensures proper padding and text color).
The data-* attributes used in Bootstrap 4 have been replaced with data-bs-* in Bootstrap 5
<button class="navbar-toggler" data-bs-toggle="collapse" data-bs-target="#navbar">
<span class="navbar-toggler-icon"></span>
</button>
Demo
As explained in the docs, data attributes for all JavaScript plugins are now namespaced to help distinguish Bootstrap functionality from third parties and your own code. This mean any javascript components (Collapse, Navbar, Carousel, Dropdown, Tabs, Modal, etc..) will only work using data-bs-... attributes.
Bootstrap 5 is a major update with breaking changes. Also see here that ml-auto/mr-auto have changed to ms-auto/me-auto.
