Hi

Please how can I use events and actions with drop - down menu ? what I mean that if I have multi choices I want if user choice one of these items will access to new slide .

There isn't a drop down menu, there is the pop up page list depending on the template you use.
You could make a menu bar, it would be a graphic with hot spots that unhide extra images for the drop downs.
You'd also need to make sure that strict navigation is turned off.

Maybe zuheir means the drop down choice in a form? Plz have a look at other threads, this question is answered there. I am not at work at the moment so cannot look in my backup for the answer :-)
