I want to write code for a Form (inputs into an advance search functionality) that certain fields are dependant on other fields. For example I want Field #2 to be grayed out until Field #1 is selected. Then depending on what the selection in Field #1 is, the <options> in Field #2 (a dropdown) would change. Can you point me to somewhere to read and learn? Thanks
You would need to do this through CSS defining classes like selected and also PHP. The best source to learn HTML and other web languages is: http://www.w3schools.com/
