When using Drop Down Navigation, your drop down menus are overlapped by Flash elements, such as an embedded YouTube video on your Feature Slider.
This is because the default behavior for Flash always overlap any sort of HTML attempting to be layered on top of it. Fixing that so that drop down menus appear correctly above the flash requires an easy modification to the way flash videos are embedded on your website. There are two methods of modifying the code, and they depend on whether you are using YouTube's newer iframe code or their older embed code.
Add the following parameter to the URL:
?wmode=opaque
Before:
<iframe width="516" height="380" src="http://www.youtube.com/embed/T6MhAwQ64c0" frameborder="0" allowfullscreen></iframe>
After:
<iframe width="516" height="380"
src="http://www.youtube.com/embed/T6MhAwQ64c0?wmode=opaque" frameborder="0" allowfullscreen></iframe>
There are two parameters you need to add to your embed code.
<param name="wmode" value="opaque"></param>
wmode="opaque"
Before:
<object width="516" height="380"><param name="movie" value="http://www.youtube.com/v/T6MhAwQ64c0&hl=en_US&fs=1?hd=1&showinfo=0"></param><param name="allowFullScreen" value="true"></param>
<param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/T6MhAwQ64c0&hl=en_US&fs=1?hd=1&showinfo=0"

allowfullscreen="true"
