Hey Guys!
I want to add a drop box on my site, containing a list of movie titles. When the person clicks on a title, the info of the corresponding movie opens on the same page, under the drop box. I want to do this to avoid having to create one page for each movie.
Problem is, I have no idea how to do this . So, can anyone link me to a good tutorial on this? I googled it already, but just found help for more advanced stuff than this!
Thx!
