With reference to the ability to edit data, is it possible to
a. Only specify certain fields for editing, and not all fields?
b. Show a visible indicator as to which fields are editable, e.g decorate the field with a bootstrap form-control class, as an example.
c. Show an accept and cancel button, e.g. a Check and a Cross icon next to the field being edited so that the user can either accept and save, or cancel and restore the previous data.
Thanks,
