how can i create dropdown list with id and value?

Hello,

Thank you for reaching out.

I am not sure about how you would like to format the dropdown, so I apologize if my answer is not suitable for your requirements.

Could you check the Dynamic Dropdown Widget (https://eu.jotform.com/widgets/dynamic-dropdowns) and let us know if that would meet your requirements?

Here is a guide showing what you can do with it: https://www.jotform.com/help/596-how-to-configure-the-dynamic-dropdown-widget

Hope this helps.

Do not hesitate to reach out if you need further assistance.
