&lt;/head&gt;
&lt;body&gt;

&lt;div class="container mt-5"&gt;
        &lt;h1&gt;Bootstrap 5 Dropdowns&lt;/h1&gt;

&lt;!-- Basic Dropdown --&gt;
        &lt;div class="dropdown mb-3"&gt;
            &lt;button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-bs-toggle="dropdown" aria-expanded="false"&gt;
                Dropdown Button
            &lt;/button&gt;
            &lt;ul class="dropdown-menu" aria-labelledby="dropdownMenuButton"&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action 1&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action 2&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action 3&lt;/a&gt;&lt;/li&gt;
            &lt;/ul&gt;
        &lt;/div&gt;

&lt;!-- Split Dropdown --&gt;
        &lt;div class="btn-group mb-3"&gt;
            &lt;button type="button" class="btn btn-primary"&gt;Split Button&lt;/button&gt;
            &lt;button type="button" class="btn btn-primary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false"&gt;
                &lt;span class="visually-hidden"&gt;Toggle Dropdown&lt;/span&gt;
            &lt;/button&gt;
            &lt;ul class="dropdown-menu"&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action A&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action B&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action C&lt;/a&gt;&lt;/li&gt;
            &lt;/ul&gt;
        &lt;/div&gt;

&lt;!-- Dropdown with Header --&gt;
        &lt;div class="dropdown"&gt;
            &lt;button class="btn btn-success dropdown-toggle" type="button" id="dropdownMenuButton2" data-bs-toggle="dropdown" aria-expanded="false"&gt;
                Dropdown with Header
            &lt;/button&gt;
            &lt;ul class="dropdown-menu" aria-labelledby="dropdownMenuButton2"&gt;
                &lt;li&gt;&lt;h6 class="dropdown-header"&gt;Header&lt;/h6&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action 1&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action 2&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a class="dropdown-item" href="#"&gt;Action 3&lt;/a&gt;&lt;/li&gt;
            &lt;/ul&gt;
        &lt;/div&gt;

&lt;/div&gt;

&lt;script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"&gt;&lt;/script&gt;
&lt;/body&gt;

<h3>Explanation of the Code</h3>
<ul>
<li><strong>Basic Dropdown</strong>: The first dropdown is a standard button that opens a list of options. It uses the <code>data-bs-toggle</code> attribute to control its behavior.</li>
<li><strong>Split Dropdown</strong>: The second example demonstrates a split button, which has both a regular action button and a dropdown toggle in one component.</li>
<li><strong>Dropdown with Header</strong>: The third dropdown includes a header for organizing the options, enhancing usability and clarity.</li>
