Minimize Menu Subcategories To See Them

hi

the page I’m on is :

if you scroll under services, you see under “BodyTalk” there are a lot of sub pages and they go off the screen and we can’t see them and that takes up the space of the entire site

how can we nest all those sub pages rather than have them ALL show at once?

I just want it to be ordered and more organized where we see just say “BodyTalk” and not all the sub pages

thank you support
