Custom field read-only

Hello,
I tried to put "readonly" in the "CSS class" a custom field, but it does not work. The contents of the field can always be changed by the user. I said that it is a field mapped by Joomla profile.
Have you an idea of solution?
thank you

Hi

Could you please edit the custom field, in the "Extra" property, enter readonly="true" or simply enter readonly. After that, I believe it should work as expected
