i want only using specification of your design to our widget can you have documentation for that ?

im already read all of this from documentation, for more information in our plugin shortcode we do Wp_query to get posts like that:
$args = array(
‘post_type’ => ‘post’,
‘meta_query’ => array(
array(
‘key’ => ‘_selected_teams’,
‘value’ => ‘”‘ . $current_team_id . ‘”‘,
‘compare’ => ‘LIKE’,
)
)
);
$query = new WP_Query($args);

can i make something to get posts in flexbox ? or i want tips to create my own bloc with your specifications to get this posts

Thank you
