        if  !view.subviews.contains(container) {
            view.addSubview(container)
            container.frame.origin = CGPoint.zero
            container.frame.size = view.frame.size
            container.autoresizingMask = [ .flexibleHeight, .flexibleWidth ]
            container.isHidden = true
        }
        if dimsBackground {
            container.showBackground(animated: true)
