I want to be able to let my site visitors choose their location/country from a drop-down list when they signup but at the minute I have to create a manual list and enter all 190+ countries as options.
You have a drop-down list with country under “Phone”, couldn’t you just take that exact piece of code, remove the extension information, and use that as a drop-down list for “Country”? It would save a huge amount of time, especially as you cannot clone a Signup Form across different lists, meaning you have to enter the same 190+ countries every time you create a form for a new List.
