Your dropdown do not have the .dropdown-menu-right, if you want to align your dropdown at the right please add this class 👍

I am new to bootstrap and would much appreciate your assistance on this one.
Thanks!
Your code works fine. So i think the problem is that you are not using the bootstrap CDNs properly.
Copy the below CDNs and paste them into your code.
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

</head>
And if you are not using CDN and are using the downloaded files then please check your paths properly i.e, did you got the files correctly in your code.
It works perfectly on my side. I think, the problem is you forget to attach the script for the javascript to work.
as stated in Bootstrap Introduction Page, you need to enter this link tag for the CSS
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
and for the functionality to work, you require javascript. Try adding this to your project, before the closing body tag </body>
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js" integrity="sha384-UO2eT0CpHqdSJQ6hJty5KVphtPhzWj9WO1clHTMGa3JDZwrnQq4sF86dIHNDz0W1" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" integrity="sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin="anonymous"></script>
It's working fine, check whether you have added these links:
place this link in the head section:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
And place these links near the end of the body section:
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

Bootstrap 4 Dropdown Menu not working?
(14 answers)
Closed 4 years ago.
Seems like a simple problem, it's likely I'm missing something obvious.
I have a card layout with a series of text / buttons / lists inside. One of these buttons is a dropdown, and for some reason the dropdown doesn't "drop". This code is copied directly from bootstrap 4's site on dropdown menu buttons, except for the button class styling (outline-primary).
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<button class="btn btn-outline-primary dropdown-toggle" type="button" id="dropdownMenu2" data-toggle="dropdown"
aria-haspopup="true" aria-expanded="false">
Dropdown
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenu2">
<button class="dropdown-item" type="button">Action</button>
<button class="dropdown-item" type="button">Another action</button>
<button class="dropdown-item" type="button">Something else here</button>
</div>
You have to include Bootstrap JS.

how can I make this date input as this ?? (arabic) from tight to left and arrow in the left side , with this default value .
you need to set 'direction' properties of your element to 'rtl' (right to left) .I've used Bootstrap for dropdown. please follow below link for more info on how to use Bootstrap dropdown.

.dropdown-menu {
