I can see you are using some custom class mi_navbar-fixed-top
to position your navbar and not Bootstrap’s default navbar-fixed-top
. Probably this causes both issues because when I put the menu in a .navbar-fixed-top
container I am not able to reproduce the issues here. Maybe you could try also adding the navbar-fixed-top
class to your navbar container and this might help, but I don’t have a clear idea since I am not able to test your complete solution.
If you still can’t cope on your own, please post some kind of live demo that I could test and optimize.
Cheers!
