Hi Everyone ,
I am novice to AEM 6.4 and came to know that there are numerous changes are incorporated so facing initial hiccups to adaptTo() . 
Coming back to the question , how to enable the newly created Component Group (Generated a AEM 6.4 maven archetype 13 project--- to Extend the core components) in AEM 6.4 to drap and drop the components on a page ?
Any leads would be appreciated.
Thanks,
Puneet
When you work with AEM 6.4 - the recommended way to set components (from a given category) is by defining the policy of an editable template.
You are no longer using Design mode. The reason is pages based on Editable Templates do not have Design Mode. A Maven 13 generated project has pages based on an editable template. Therefore Design mode does not exist in those pages.
To add a component group, you need to select from components from the component group by using the editable templates Policy.
See this HELPX artilce to learn more about editable templates and how to set policies to allow components (within a specific component group).
You can also watch -- Scott's Digital Community: Guided Journey for Experience Manager on Editable Templates
So to use a given component in a page based on an editable template - you must allow that component in a policy - as discussed in the article and shown in the series of videos.
Hope this helps....
