Hi,
Somehow we have to edit the org-ehtml-server.el and the org-ehtml-client.el
file in order to the edit the orgmode file as editable web page where we
can edit the headings
or subheadings.

functions defined in the org-ehtml-server.el file

(provide 'org-ehtml-server)
This provides the org-ehtml-server function on the backend side to export
the org-ehtml file as editable web page and make the changes to the
org-file on the server side to the org file.

(provide 'org-ehtml-client)

this provides the org-ehtml-client where the client can make the changes to
the org-file viewed as an editable web page and editable function (defun
org-ehtml-client-editable-p (element info).

If anyone comes with some solution to make the org-file exported as an
editable web page where one can edit the parent headings and subheadings of
the content , kindly reply back.

Thanks
Nitin Agarwal
