On a Nodemcu, Is it possible to add a drop-down box to the html wifi setup page?

Hi Juraj,

I appreciate your help and code but I am clearly at a level far below yourself.
Completely lost with what you sent through, is it some sort of clock? Wouldn't compile for me...

Without complicating things this is what I am trying to do:

On the WiFi Setup page have a dropdown box

Label = "Select Currency:"
Options = "BTC,XLM,ATLAS"
Values = "btc-api-url,xlm-api-url,atlas-api-url"

When selected and saved, variable 'Currency=value' is saved to eeprom
Then in main code (after a reboot & connection to network specified in setup) be able to use the variable 'Currency' ie the api url of the currency chosen at setup.
