I am creating a e learning site where i want provide my visitors a functionality to get the results which they need .
Suppose a visitor needs to find the colleges in a particular location. So I want to filter the results by providing them a 3 drop downs like State , On selecting state it should display the cities and finally select the course and on submitting they get the required result.
I don't have the idea how to do it. Please help me with your valuable suggestions.
Thanks
