I like to detail my case first.
I have 2 collection:
Collection 1: list of States (1 Field ) - pic attached
Collection 2: - pic attached
1. List of towns (first field)
2. City of towns this follows first field info (second field)
3. State of city this follows second field info (third field)
- When I change value at first dropdown (State) I want the second dropdown (City) has just cities in that State are listed out. Then, The third dropdown choices follow the second one either. Thank in advance! Please I need it. I am not good at code.
