How to display menu bar over slideshow block? On my site, I am not able to show menu bar over the slider block in content. When I click the menu over the slide image, part of it disappear under the slide block.

When I click on the Services menu, it shows odd things. This problem is not persist on IE.
You can increase the z-index property of your menu bar. 

If this does not help, add the position:absolute property in CSS class; and also add the position:relative property to the container of the menu bar class.
