html - Menu links not clickable -

-

i have defined in code link go page, not going anywhere when click it.

if go page: http://www.davidhechtkitchens.com/ , try click on "portfolio" in top navigation nothing. if @ code you'll see it's defined go portfolio.html.

this problem seems in effect when there sub-menu underneith top link. if remove sub-menu "portfolio" works.

it seems have kind of script active prevents default action,

while checking source code, when click on button adds class anchor. (in cases made make work on mobile devices)
