Please note that official support for this menu version has now ceased. There are still plenty of users, though, and the forum is still running. Some of our long-time users may be able to help you out.
I'm designing a site so that a vertical menu appears on the right side of the page. Thus, I need the subs to open up to the left of the main menu. How do I do that? Thanks in advance for any help.
Increase the value of suboffset_left= towards the top of your array. Depending on the width of your menu you might want to start with a value around 200 or so and then go from there.
