I am building my new website and I am going to use the "dyanamic" menu system. I was only thinking of using one level of options. But anyways, what is the best ways to position the first layer on screen (the one that starts out hidden, and when you roll the mouse over the main topic, it appears). Should I use position:absolute in my style sheet or is there another way to do it? How is it usually done? Also, if anyone can give me some tips for writing the JavaScript for it I would appreciate it.
