            var_dump($get);
            $templatecontext=(object)[

            $this->content->text=$OUTPUT->render_from_template('block_add/manage', $templatecontext);

        }else{
            $this->content->text = $mform->render();
        }

        return $this->content;

    }




    function has_config() {return true;}
}

This is the code that is design by me.
