How to Convert JSON Data into Dynamic Select Boxes in HTML Tables

If you have JSON data that needs to be presented in a more interactive way, displaying values in select boxes inside an HTML table is a great solution. For instance, showing all corresponding values in a 'country' field as select options enhances user experience. In this post, we will explore a step-by-step method on how to convert JSON data into dynamic select boxes within an HTML table.
