Hi @sreenu539 ,
No, the ootb Content Fragment Models in AEM do not provide a "composite multifield" data type. The CFM schema supports basic data types such as text, number, date, boolean, and path. To achieve a composite multifield functionality, you would need to create a custom data type in your CFM. This can be done by extending the existing data types or implementing a custom data type using Adobe Experience Manager (AEM) Core Components.
There is no specific data type for images in CFM. However, you can use the "path" data type to reference the path of an image asset in the repository. This would allow authors to select an image asset using the path browser or by entering the path manually.
