On Dreamweaver I used the option of making a navigational bar. I used my own images for the links and when your mouse goes over it the img spins. I am wondering if it is possible to have it where when you put your mouse over the button can I have it to where a little menu screen comes down and shows other links. As if it was a drop down menu. Thank you.

If you show the behaviors menu under windows there is a pop up option. You need to make sure you have the link highlighted (and if its not actually a link just put # in the link line). Then in the behaviors column click the plus arrows and down at the bottom is the pop up menu option. Hope this helps!
