AEM - Restrict Component Editing and Allowed Only for Certain Users

Disable Component Editing via dialog except few users

In AEM majorly content is created using component's dialog. Sometimes few type of contents is meant to be edited only by certain authors and are not suppose to modify or create by other authors.
In this case how can we protect these type of components should not be updated by non-authorised users.

In AEM when a component in a web page is rendered, an HTML element can be generated, wrapping the rendered component within itself. This primarily serves two purposes:

• A component can only be edited when it is wrapped with an HTML element.
• The wrapping element is used to apply HTML classes that provide:
• layout information
• styling information

More info about Decoration Tag available at Decoration Tag

If  cq:noDecoration {boolean}, This property added to a component and a true value forces AEM not to generate any wrapper elements over the component.This property set the decoration tag based on boolean value.
But decoration property can also be set programatically, [JAVA API]


In Java code if we check current user against the allowed group(s) and if user member of allowed group we will set decoration tag otherwise not.This will serve our purpose for this use case.
