I have a webpage based on Joomla that is using the Sobi2 component. Entries made into the database are displayed on my webpage and categorized into various categories and sub-categories. I need a three stage drop down filter that filters the entries into the State ([url removed, login to view]), County (e.g. Los Angeles) and Local Area (e.g. Los Angeles and SF Valley).
The "filter" would need to be applied to the Local Area selection. I would want to define a row of zip codes (90065, 90066, 91355,....) used to filter the entries pictured on the page and also behind the tree of categoeries and sub-categories.
Attached is a pdf file sort of depicting what the idea is.
please contact me if you have further questions
