[yuri]

In detail and edit view classes you can write

setup: function () {
    Dep.prototype.setup.call(this);
    if (this.getUser().isAdmin()) {
        this.hideField('myField');
    } else {
        this.showField('myField');
   }
}

I create some custom fields from the from an existing entity. I added the fields to the layout. My question is, is it possible to make these fields visible only for non-admin users?
