<!-- To make the dropdown interactive, you would typically use a small amount of JavaScript.
     For example, a simple toggle on button click to add/remove 'hidden' class from the dropdown panel.
     Since the prompt strictly forbids JavaScript, this example shows the structure 
     and styling for both states (button and dropdown content) as per Tailwind CSS usage. -->

<!-- To simulate interactivity for demonstration, you can manually remove 'hidden' class from the dropdown panel div.
     Example: <div class="origin-top-right absolute right-0 [...] z-10" role="menu" ...> -->
