hello, I have website where I am using flyout_menus.js for dropdown menu and jquery javascript which I need for masonry. I found that in pages that there is jquey the dropdown menu does not works. What can cause this and how can i fix it?

here is the website under construction but you can see the problem, in the first page the dropdown menu does not work, if you go to "press" page you will see that there works because I am not calling jquery.

thanks for any help
