Customize a Mapquest map for a Leisure website (1676829)

This project is for a local Leisure and Activities booking website. It's based off a shopping cart software running on PHP, and MySQL + Few Ajax features What I would like to do is this: - whatever product show in a page (wether it's a search results, category page, etc?), these product will show dynamically in the map depending on what filters the user changes. - The filters will be showing on the left side of the map. Basically what I'm looking to achieve you can see in those examples: - [login to view URL] - http://www.travelocity.com/experiencefinder/#subSection=Maps|section=Tools|destinationId=108 Please let me know your thoughts and I'll provide you with more details.
