</html>I just started learning Javascript and I've developed a Shipping Method Page. When the user clicks on the "Add Delivery Address" link, an address form is displayed. After filling out the form and clicking the "ADD NEW" button, the data should appear in the select menu option. I'm encountering some difficulties in implementing this feature. Could someone please provide guidance on how to achieve this? Your help would be greatly appreciated. Thank you
