            $("button.btn.btn-invisible.btn-dark").css("display", "none");
            $(".filter-definition-container").css('pointer-events', 'none');
            $(".choice-filter-clickable").css('pointer-events', 'none');
        }
        /*else if (!_.isEmpty(this.model.get('department')) && this.model.get('department') != null && this.model.get('type_2') != null && this.model.get('subtype') != null) {
