hi

is there a custom field that can be set to read only on the front end but can be overridden by super admins?

we need to place a sort of notification field on the FE for users. basically its read only on their side. i cant use the "custom text" field type because you can not change the field content per user.

i need something like for user 1

custom field = " please complete your user proile "

user 2

" congratulations "

user 3

" thank you, you are now a gold member "

something like the above.

i tried to use "text filter" type and set it to read only,it can't be overridden even in the back end. if i try to set it to super admins only and turn off read only, we can use it but it cant be seen in the front end.

thank you
