Hi all! This is about a HTML Dropdown in the mobile Version of an interactive Worldmap. Works fine for me on iPhone and Mac. Since I can't test it myself... I would be very interested to see how it looks on an Android phone or a Windows computer/Internet Explorer.
…and with Windows, there's VirtualBox… https://www.virtualbox.org …but you'd need the Windows operating system. I'm not sure if it will run Windows on Apple Silicon though.
I think there are websites / software specifically for testing cross platform too.
