Unlink menu category

Hi, how to unlink menu item "Skupstine stanara" http://www.firstfacility-belville.net/ I want to disable option to have a link on this menu item. If someone click on link "Skupstine stanara" he will see a message: Nothing Found It seems we can’t find what you’re looking for. Perhaps searching can help. I want to click on this menu item in order to get submenu items - nothing more. regards, Djapeto
