taxonomy-portfolio_entries.php

Hello
I would like to change the grid layout of taxonomy-portfolio_entries.php to masonry.
I saw it was this code :

$grid = new avia_post_grid(array(	'linking' 	=> '',
                                                        'columns' 	=> '3',
                                                        'contents' 	=> 'title',
                                                        'sort' 		=> 'no',
                                                        'paginate' 	=> 'yes',
                                                        'set_breadcrumb' => false,
                                                ));
                    $grid->use_global_query();
                    echo $grid->html();

Is there a simple way to call masonry instead of the grid ?
Thanx !
