const myList = new ListExtender();- Append your list to some parent container in the DOM
myList.appendTo("#containerId");And that's it! You now have a working extending list in your website!
From here you can customize the list however you see fit. A good place to start would be setting the placeholder and input type.
myList.setPlaceholder("Placeholder Text");
myList.setInputType("email");
