I'm designing a webpage where the user needs to input location (city, county, state, country) information for a project. But the project can span more than one location and the information for each location may not be complete. eg: User might want to enter location Arizona, USA for Project1. For project 2, there might be two locations like Phoenix, Maricopa country, Arizona, USA and Pima county, Arizona, USA. How do I make my web page flexible enough to handle (a) one or many locations and (b) for each location specified, city, county, state and country fields? I'm thinking of text boxes and dynamic dropdowns (like if you select Arizona, county dropdown gets filled with all AZ counties) but am worried that page will become two complex as multiple locations are also possible. Are there better ways to design this kind of page?
