Reordering modules and their contents

We will implement a JavaScript drag-and-drop functionality to let course instructors reorder the modules of a course by dragging them. Drag-and-drop enhances the user interface, offering a natural way to reorder elements that is more intuitive than using numbers or clicking buttons. It is also a time-saver for course instructors, who will be able to reorganize course modules and their contents easily.

To implement this feature, we will use the HTML5 Sortable library, which simplifies the process of creating sortable lists using the native HTML5 Drag and Drop API.

When users finish dragging a module, you will use the JavaScript Fetch API to send an asynchronous HTTP request to the server that stores the new module order.
