What is the reason behind the persistent presence of the caret in my dropdown button?

Is there a way to remove the caret next to a chat icon button in a dropdown menu? I am using Bootstrap 4 and have tried this:

.message-notification-chat-icon-mobile .dropdown-toggle::after {
  display: none;
}
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="096b66667d7a7d7b6879493d273c">[email protected]</a>/dist/css/bootstrap.min.css" integrity="sha384-TX8t27EcRE3e/ihU7zmQxVncDAy5uIKz4rEkgIXeMed4M0jlfIDPvg6uqKI2xXr2" crossorigin="anonymous">

<button class="btn dropdown-toggle ml-auto message-notification-chat-icon-mobile" type="button" id="dropdownTopMenuMessageNotification" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" id="messageNotificationIcon">
        <i class="fas fa-comment"></i>
    </button>

Answer №1

To make it work, simply eliminate the class dropdown-toggle. If you are unable to remove it for any reason, you can achieve the same result by making adjustments in your CSS code.

.message-notification-chat-icon-mobile.dropdown-toggle::after {

You can see both methods demonstrated in the code snippet below: 

.message-notification-chat-icon-mobile.dropdown-toggle::after {
  display: none;
}
