double horizontal drop-down with third level vertical drop-down
I want to make a double drop-down horizontal menu with a third level of vertical links. The first horizontal menu will lead to a second horizontal menu; this menu will change depending on the link chosen in the first menu. That second menu will lead to a third level of vertical drop-down menus. Is this possible to create with CSS menu writer?
Here's the very rough draft of our new home page with the menu that kinda works. It's a code I found online and has lots of bugs. I'm hoping to code something similar:

Can I do this with CSS Menu Writer? I couldn't find a tutorial....
