I need a php page and at the top is a dropdown (city) and a second dropdown next to it (category). After the user selects the city then category a list from the database is displayed below with just the names. When a user clicks the name, and 'window' (light lightbox) is opened in the center of the page with the following fields.. name, address, city, state, zip, phone, website, facebook link, twitter link. If they click the X at the top right it closes or if they click outside the box (anywhere else on the page) the box closes. On Ebay when you go to the main page and click a suggested item, it opens a window.
If the user selects a different city the page immediately updates. Same with category.
The admin page has the same functionality but allows you to add/edit/delete items.
Also has security for an admin log in..(just one, nothing special).
