Header.swift

    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
        guard let menu = menuView else {
            return super.point(inside: point, with: event)
        }
        
        let menuPoint = convert(point, to: menu)
        
        if menu.point(inside: menuPoint, with: event) {
            return true
        }
        
        return super.point(inside: point, with: event)
    }
    
    override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
        guard let menu = menuView else {
            return super.hitTest(point, with: event)
        }
        
        let menuPoint = convert(point, to: menu)
