Hello there,I'm am 12 years old and and a web page designer. I really need this to finish this client's website I have. I'm looking how to create a changing drop down menu. Kindof like the ones you might see in checking out from buying from a website. For Example:Click Your Country:United StatesCanadaIf the user selects United States, all the states would be the same. Same thing with selecting Canada.Thanks,Derek
