And one more thing it will also have main city and sub cities like main category and sub category but user can only select sub city not main cities. And in website where there are city field they should be changed to select box. example for city and sub-city structure:- Navi Mumbai [User can't select this value] - Panvel - Kamothe - Khandeshwar Mumbai [User can't select this value] - Dadar - Parel [login to view URL]
