What functionality is used to create custom fields in Liferay?

The ability to create custom fields in Liferay is primarily handled through Object Management. This functionality allows developers and administrators to define new object types and customize their attributes, including the creation of custom fields. Objects can be tailored to meet specific business requirements, enabling the addition of fields that capture unique information relevant to a particular application or use case.

Object Management encompasses the design of data models that are flexible and extendable, allowing users to specify the types of data they need to gather and how it should be structured. This capability is essential for applications that require specific data handling beyond the default fields provided by Liferay.

The other options, such as Theme Management, Site Configuration, and User Administration, focus on different aspects of Liferay's functionality. Theme Management pertains to the visual aspects of sites, Site Configuration is about managing site settings and global configurations, and User Administration deals with managing user accounts and permissions. None of these directly contribute to the creation of custom fields in the same way Object Management does.
