Hi lic,
Welcome to the SEBLOD forums.
Yes! For any field that has a label, it can be hidden by using either a space or "clear" (without the quotes) in the Form & Content Type editor in the Label Section (#1 option). If you want to show text only have a look at the Free Text Field. If you only want to show a Free Text Field in the admin section, then do not add the field to the Content View.
Hope that helps,
Randy
