I integrated the hamburger menu on a website
http://www.mrskate.nl/meesteres-kate.php
When I decrease the width of the browser window and apen the hamburgen menu the popumenu is not in foreground

The normal menu is OK,
But as soon as the hamburgen menu is activated and you click on the hamburger to open the menu this problem appears.
on other browsers the menu is without this problem.
greets,
Bert
