Drop down menu hidden behind wowslider

Hi, the drop down menu in my page is hidden behind wowslider. I use wowslider instead of using slider box because I’m using Andrina Lite free version and it don’t have option for me to add more images to the slider box. So, I deleted the codings for slider box in my ‘front-page.php’ file under editor section.
This is my page: http://www.noordinstreethouse.com/

Anyone have ideas? Please help me.
Thank you
