let containerV = UIView(frame: CGRect(x: 0, y: 0, width: self.frame.size.width , height: 50))

containerV.layer.shadowColor = UIColor.black.cgColor
containerV.layer.shadowOpacity = 1 
containerV.layer.shadowOffset = CGSize(width: -0.5, height: -3.0) 
/* since we dont want shadow at bottom */
containerV.layer.shadowRadius = 2
containerV.layer.shadowPath = UIBezierPath(roundedRect: containerV.bounds,
