The user is needed guidance on how to hide some fields in the Portal forms :
a) in the registration form we would like to hide field "Description"
b) in the organisation edit form, we would like to hide the field "Description" too (to mimic registration form)
c) in application edit form on the last tab (Auth) we would like to hide fields "Scope" and "Type"

It is sufficient to visually suppress the fields.

The user would also like to restrict editability of 
a) organisation custom fields in the organisation edit form
b) e-mail in the user profile

Is there any way to restrict editability of fields, so that the front-end user (external) cannot edit them?
ENV: Portal 3.5 CR09
In version 3.5, currently, the only action that is supported in the portal is to disable the Description field from appearing in the register form by navigating to the Custom Fields dashboard page and disabling the Description field. 

There is no way to remove or force a ready only state for the other fields mentioned.
