Create extra fixed menu on top?

Hi, I have already used the (fixed) top menu for a menu, but I want to have another menu bar there (preferably even higher then the current top menu). I have gone through the default wordpress tutorials of creating an extra menu, but then my new menu ends up in the wrong place (below the top menu) and it does not stay fixed when scrolling down. Is it possible to create an extra menu-line on the top of the page? So I want the page to look like this: : first menu line (to be added, menu stays on page when scrolling) : second menu line (currently the top heading menu, menu stays on page when scrolling) : header image : main menu : page content Thanks a lot in advance!
