We have a requirement where there are 3 different properties
country - which has dropdown list with (US,Canada,UK) value
City - which has dropdown list with(detriot,Newyork,Toronto,London)
ZipCode - which has dropdown list with(12345,34fn8,23456)
Now we would like to setup a relationship such that when the user select country = US they should see only option of detroit and newyork as city and once the appropriate city is selected they should see the related zipcode
How can we achieve this?
