All the options for page information can be found here: /libs/wcm/core/content/editor/jcr:content/content/items/content/header/items/headerbar/items
Overlay this :- /libs/wcm/core/content/editor/jcr:content/content/items/content/header/items/headerbar/items and
the JSP for hyperlinking is :- /libs/granite/ui/components/foundation/hyperlink/hyperlink.jsp
I hope this will help you.
