how create 3 dropdownlist display countries, states , cities. when select country automatically shows states name of country in next dropdownlist. when select state, cities dropdownlist fetch related cities state.
drop down list created here.
the easiest solution might create own custom controlled vocabulary , use dspace controlled vocabulary lookup mechanism.
if don't wish go controlled vocabulary route, see 2 options:
- define field 1 of standard input form types in input-forms.xml inject javascript submission process transforms series of drop-down boxes. other injecting javascript (how differs between xmlui vs jspui , between xmlui themes), change need no code customisations.
- extend set of input form types available include 1 meets needs. requires code customisations. have inject javascript code enables dynamic behaviour describe (narrow down state country etc).
