I have a Country dropdown ( Option set) and a Region dropdown ( which I would also like to have as an option set).
I would like to display the regions that correspond to the selected country.
Can you tell me how to do this?
You can use attributes of an option set. Simply, add a new attribute to your Countries option set and add the corresponding regions. See the screenshots below:
Maybe explain what you are trying to do rather than small issues. Maybe there is something you are missing in the big picture. What is the high level goal you are trying to do?
