Adding Sub-Options of Custom Data
Maybe I didn't know, but I didn't know.
I need to add a sub-option to private recipients. I can explain this with an example.
Suppose you have an option. When I make a choice here, there must be sub-options that are optional in this option.
In the meantime, there is City / County option, but when I choose the province does not come from the county information. (For Turkey)
