Hi there,

It is possible, with a code snippet, to also add support for a custom taxonomy in dynamic rules - usually the brand is a taxonomy.

The snippet to add is:

add_filter('b2bking_dynamic_rules_taxonomy_option', function($val){
    return 'brand';
}, 10, 1);
add_filter('b2bking_custom_taxonomy_backend_name', function($name){
    return 'Brand Name';
}, 10, 1);

Here it sets it to a 'brand' taxonomy instead (assuming that's the slug of the taxonomy and not something else).

That should result in brands becoming available for selection in rules:

Let me know if that works for you,

Kind regards,

Stefan
