Would it be possible to define using jquery 3.3.1 a default character that cannot be removed from an input? ex: An input has a @, and only 20 letters and/or numbers may be added after this @, but the @ can’t delete. I tried to set using the value="@" html. But to delete. How to make it not removable?
You cannot add @after?

On the front end I tried only with atrubuto value, but da para remover quando clica no input
