how to overlay content.xml of core/ other component to remove and add certain fields? in AEM as a cloud service

[rahul234dabas]

Hi,

I want to know like while overlaying a component how to overlay content.xml 

e.g : 

-> component that is being overlayed: component A

-> component that is overlaying: component B

now ->I have some fields in component's A dialog box that I don't want in component B's dialog box

        -> Also I want to add some extra fields in component B's dialog box which are not present in Component A

can anyone help me to know how can I achieve such functionality? 

Thank you

Hi @rahul234dabas

Hello @rahul234dabas 

Please refer to https://experienceleague.adobe.com/docs/experience-manager-64/developing/platform/sling-resource-mer... as well.

The Sling Resource Merger provides us multiple options:

• sling:hideProperties ( String or String[])

  Specifies the property, or list of properties, to hide.

  The wildcard * hides all.

• sling:hideResource ( Boolean)

  Indicates whether the resources should be completely hidden, including its children.

• sling:hideChildren ( String or String[])

  Contains the child node, or list of child nodes, to hide. The properties of the node will be maintained.

  The wildcard * hides all.

• sling:orderBefore ( String)

  Contains the name of the sibling node that the current node should be positioned in front of.

Thanks,

Aanchal
