adding parsys from code in aem 6.5

Yeah, you should be able to add the parsys and this is very commons requirement. The new parsys is located at: wcm/foundation/components/parsys/newpar

Yes, you should manage this in the code and here is the sample snippet how you can include parsys in the component: 

<sly data-sly-resource="${'myComponent' @ resourceType='wcm/foundation/components/parsys/newpar'></sly>

You can look at the tabs and carousel core components for more info.

Thanks,

If you are drag & dropping a component(which has child/nested parsys in it) into layout container responsive grid of editable templates then all the components which are allowed in that particular layout container policies at editable template level are by default allowed to add in that child/nested parsys inside that particular component.

/content/page/jcr:content/root/          -       layout container root (say you have allowed 'x' component group or 'y' components by editing template or through code by defining policies under /conf/project/settings/wcm/policies/wcm/foundation/components/responsivegrid/policy_34324324 & map this to policy as value to cq:policy property under /conf/project/settings/wcm/templates/content-page/policies/jcr:content/root)

Drag & drop component A

/content/page/jcr:content/root/componentA/       -       component A

Component A has parsys in it say 'new_par'

/content/page/jcr:content/root/componentA/new_par     -     this parsys new_par by default inherited/enabled with 'x' component group or 'y' components which allowed in parent layout container responsive grid.

to answer your query we can set this allowed component policies through code or by editing templates as well.

Just add the following line of code inside wrapping HTML div

<sly data-sly-resource="${'par' @resourceType = 'wcm/foundation/components/parsys'}"></sly>

or else you can also use a responsive grid where we can set policies to allow list of component.

<sly data-sly-resource="${'responsive-grid' @resourceType = 'wcm/foundation/components/responsivegrid'}"></sly>
