"Drop down menu"

I'm using the Startup Template but I can't use the drop down menu like the demo of the site.
any solutions please?
the site I'm building is
http://www.anastasischetas.com

Sorry, but your page says:
"This webpage has a redirect loop"
and redirrects to:
"http://www.anastasischetas.com/index.php//"

Sorry try this link
http://www.anastasischetas.com/index.php/en/

I have checked the site and it reacts exactly like demo - there is only one menu item with subitems that drops them down on hover.
