Hi! I’m not sure I understand very well what you mean. Do you experience the same behavior on the following page:
http://vadikom.github.io/smartmenus/src/demo/bootstrap-navbar.html
If not, please post some kind of demo of your implementation and try to explain what exactly is wrong with it so that I could investigate the issue.
If yes, then please try to explain a bit better what exactly you mean (e.g. what you are doing step by step and what you are expecting to happen).
Thanks!
