Hi armanemadi ,

It is going to require some PHP & Joomla! knowledge to get a double-drop-down working.

There is a basic tutorial here and a link at the end to a second paid tutorial using Ajax.

The first tutorial has some bugs that are discussed in the forums which I why I suggested that you read those posts first.
