		this.options = options;

		if (OS_ANDROID) {
			this.containerView = Ti.UI.Android.createCardView({
				touchFeedback: true,
				elevation: options.viewShadowRadius || 0
			});
		} else {
			this.containerView = Ti.UI.createView();
		}

		this.containerView.applyProperties(Object.assign({
			// Cross platform
			viewShadowRadius: 16,
			borderRadius: 10,
			backgroundColor: 'white',
			// iOS only
			viewShadowColor: '#4d000000',
