I am interested in the implementation of the panel in the gusto.com announced here serveral days before.The panel locates in the left side of such a url as: http://www.gusto.com/newyork/newyork-CityRestaurantFinder1744251.html?character_id=1041# The lists are type,theme,features,etc I think it is ajax style,can the developers tell me how to implement such a panel? very grateful! -- Posted via http://www.ruby-forum.com/.
