Iparsys (Inherited Paragraph System): The name itself represents the Inherited, it means whenever you add any component in the iparsys then the component will be inherited to child pages. Examples: Header and Footer, these components are authored on the Parent page but by default those components will be inherited to child pages. If we want to add a new header in iparsys in the child pages then we need to use Disable Inheritance and Cancel Inheritance . Disable Inheritance : If we disable Inheritance for the Iprays then the Inheritance will be disabled for current Page and child Pages . Cancel Inheritance: If we Cancel Inheritance for the Iprays then the Inheritance will be disabled for child Pages not for current Page .
