I’m having a problem determining why there are lines at the top of the sub-menu for a JQuery menu that I’m trying to implement. This problem does not exist when I run the demo and I’m using the same browser. I downloaded the demo from here: http://apycom.com/menus/11-black.html

Here is the link for the development site: http:www.websitedevelopers.com
Thank you in advance for your insight into this problem!
Those lines were border-top and border-bottom set for li tag as below,
And the
float:leftdefined for the menu seems to mess up the li items,menu.css -> line 24
Please remove the
float:leftfrom above and try.
