Hi I have three drop down lists in my webpage. called following
Country, County, and category.
What i want to do is link them to a backend database that i have created but when i pick a Country the county drop down list should only show me the counties in that country and then when i pick a county it should only show me the categories in that county.
So for example pick UK (in Country) then shows uk counties (in drop down list County) and then pick county which shows all the catergories (in Catergories drop down list)
Any tutorals or any examples i can follow
Any help is much appreciated
