I am using the related select plugin for jquery mentioned http://www.erichynds.com/examples/jquery-related-selects code: https://github.com/ehynds/jquery-related-selects It works ok I have no problem with it. Lets say i use it on `example.php` page. Now what i want to do is to somehow prepopulate the selects when i open some link in following format. example.php?stateID=so&countryID=coun the passed parameter are the selected options for the menus. The StateID is dependant on CountryId selection and the former is populated after selection on countryID Meaning that I dont have to do selection for menus if i have provide PHP parameters
