Hi, I am new here and let me open with the question which is the reason I joined this site:
I have a selection box multiple with countries which supports multiple selections being made. Depending on the Country or Countries selected in the countries box I want to change the options in the State box. I have got it working when only one Country is selected. Problem is that the State values are reset when I select multiple countries.
Is there a way to get the following: A client selects the USA from Countries. The State box is filled with the US states. Now when the client also selects France from Countries the list of US States remains and the French States are added giving me a list with both the US and the French States?
I have looked everywhere but cannot find this being done anywhere.
