hey there i'm looking to create a yahoo or google type of menu system where the top part says search/images/news etc.etc. you click on a link and it changes the search box to whatever the users wishes.. I thought it was DHTML but i can not find that type of script anywhere and someone suggested it maybe javascript - can someone clue me in a bit more on what that type of menu would be called and maybe where i can find some more information on how to create one similiar?

Thanks in advance,
Bill
