I am encountering an issue while trying to implement a tab with a dropdown navigation, similar to the examples shown on Bootswatch. Interestingly, it seems that this functionality is not working properly even on the demo page provided by Bootswatch.
My main objective here is to have one of the tabs contain a dropdown menu that changes the content displayed in the tab body based on the selection made. While the other tabs are functioning as expected, the dropdown menu fails to show the intended contents.
Below you will find a simplified version of the code from the Bootswatch page example:
<!doctype html>
<html lang="en" class="h-100">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<title>Title</title>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootswatch/4.4.1/cerulean/bootstrap.min.css">
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.5.0/css/all.css">
</head>
<body class="d-flex flex-column h-100">
<header>
<nav class="navbar navbar-expand-lg navbar-dark bg-primary">
<a class="navbar-brand" href="/">Title</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor01"
aria-controls="navbarColor01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarColor01">
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a class="nav-link" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link active" href="#">Settings <span class="sr-only">(current)</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Help</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</span></a>
</li>
</ul>
</div>
</nav>
</header>
<main role="main" class="flex-shrink-0">
<div class="container" id="settingsapp">
<div class="page-header" id="banner">

</li>

</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button"
aria-haspopup="true" aria-expanded="false">Dropdown</a>
<div class="dropdown-menu" style="">
<a class="dropdown-item" data-toggle="tab" href="#dropdown1">Action</a>
<a class="dropdown-item" data-toggle="tab" href="#dropdown2">Another action</a>
</div>
</li>
</ul>
<div id="myTabContent" class="tab-content">
<div class="tab-pane fade show active" id="home">
<p>Home tab content.</p>
</div>
<div class="tab-pane fade" id="profile">
<p>Profile tab content.</p>
</div>
<div class="tab-pane fade" id="dropdown1">
<p>Dropdown 1 content.</p>
</div>
<div class="tab-pane fade" id="dropdown2">
<p>Dropdown 2 content.</p>
</div>
</div>
</div>
</main>

This particular endeavor has proven to be a bit challenging for me, but I view it as an opportunity to learn and improve my skills in this area.
