Modal or Dialog Not Closing Properly

1. Close button onClick not calling state setter
2. Missing or wrong modal state check in render
3. Backdrop click handler not closing modal
4. Modal z-index conflicts with other elements
5. Multiple modals mounting without parent controlling state

Implement controlled modal with proper state:

const [isOpen, setIsOpen] = useState(false);

return (
  <>
     setIsOpen(true)}>Open Modal
    {isOpen && (
      
 setIsOpen(false)}>
        

           setIsOpen(false)}>Close
        
      
    )}
  
);
