Hey Denis,
to be frank with you, this situation was left intentionally since the vast majority of the websites do not display admin back-end to their users. However, I’ve took the time now and found a more elegant way to position the submenus so that they appear where they should both for logged in and all other users. I’ve made the respective corrections in your style.css file (for the record: I’ve changed one declaration for the #nav-primary ul li ul element (line 407) – deleted “top: 33px” and added “margin-top: -9px” instead). Thanks for pointing this out, will include into the latest update as well!
Sincerely,
Andrew | Satori Studio
