I'm creating a directory, and the client wants to be able to be able to see categories, then listed by cities. For example, the main categories might be Hotels, Coffee Shops, Gyms, Movie theaters, etc. I assume this would be in the Category widget that's included in the theme. I was thinking of clicking on Hotels, and it takes you to a Hotels page, and lists all cities that have Hotels listings. Then, clicking on one of those would take you to a listing of hotels in that city, and finally clicking one of those would take you to the ad. I was thinking of doing it starting with country, then state (or city), and finally the category, but I think it's backwards like that, as each city/state will have the same categories... At the same time, these need to be searchable by using the search boxes. That's a whole other thing for the future though. Thanks for any advice.
The way you want to organize the Listings would be possible only through Custom Coding. What I will suggest you do is Create Main Category based on Name of Cities: Lets Say: New York, Washigton Then create Sub Category under each of both Cities: Like Spas, Gyms Then Add listings and assign them the Main Category->New York and Sub Category->Spas After that put the categories widget in the Sidebar and navigate to listings based on Cities or Type of businesses.
