on this website http://hauntedwisconsin.com/events/list/
is a menu - sort by zip or address, filter by type, when a visitor inputs a city the php in the box below changes and displays the information (in the events list below in the center of the page) and if a visitor picks a type of event the php in the events list changes below. IS this totally a html5 css3 function using the object redirect? or is it a function of php that makes this work? I would like to use this on countyfairgrounds.net but do not know how to implment this Can you help me?
