Thats ok, i got worried that support disappeared. Im using latest version of meta box. I have the following extensions as well, fully updated:
term meta
include exclude
columns
Code is below:
$meta_boxes[] = array(
'id' => 'restriction_targeting',
'title' => esc_html__( 'Targeting', 'your-prefix' ),
'post_types' => array( 'restrictions' ),
// List of meta fields
'fields' => array(
array(
'name' => esc_html__( 'Categories', 'your-prefix' ),
'id' => $prefix . 'categories',
'type' => 'taxonomy_advanced',
'taxonomy' => 'product_cat',
'clone' => true,
'field_type' => 'select_tree',
'query_args' => array(),
),
)
);
