no flyout cs menu dropdown

Question

Hi Guys

I wanted to make a menu that does not flyout when you hover over the first child li.

For example:

Home | Services | Products | Contact Us

• under services, for instance, you have a dropdown that enumerates: Services A Services B Services C

all vertically like the usual drop down, however, if services A have submenus i don't want ti to flyout to the side but rather occupy the same vertical space that will move Services B, C, etcc down as well.

Can someone point me to the right tutorial?

Highly appreciated.

Thanks a lot!
