Hi ,
In Cascading drop down(based on selected country corresponding states should populate based on states cities should populate)
which is best approach to follow:
1) select the country id and pass the id to states table to get the corresponding states( here every time when i select the country i am hitting the Data base to get the states list so data base operations are more here )
(or)
2)load all countries and states at once populate accordingly (here unnecessarily we are loading all )
is there any better approach ?
