Undefined variable inside demo script

[toplisek]

I have tested and it reports Undefined variable:
jQuery('.dropdown-toggle').dropdownHover().dropdown();
jQuery(document).on('click', '.fhmm .dropdown-menu', function(e) {
e.stopPropagation();
});

How to avoid this error as it is actually from demo version? Need help.
