Need to add heading in between checkboxes

if(!$ids) return $scanned_tag;
    foreach($ids as $id) {  
		$id = $id;
		$cat = get_the_terms($id, 'event-cat' ); 
		$data =  get_field('start_date',$id ).' - '.get_field('end_date',$id ).' / '.$cat[0]->name.' / '.get_the_title($id); 
        $scanned_tag['raw_values'][] = $data. '|' . $data;
    }

    $pipes = new WPCF7_Pipes($scanned_tag['raw_values']);
    $scanned_tag['values'] = $pipes->collect_befores();
    $scanned_tag['pipes'] = $pipes;
