I have a HTML page with couple of div and 2 drop down list . values in drop down list is loaded based on selection made in list 1 (both the list are getting values from DB), such that Every time user selects a value from drop down list 2 .. value is passed as as parameter and the page is reloaded to display the values in div present on the page.

Problem is with the refresh of page select list values are also refreshed and user is again asked to select the values from the list.

As per my knowledge we can store single values in cookies .. is it possible to store a list, also apart from cookies is there any other way to store entire drop down list on client side ?

I am using php for server side scripting and java script on client side
