query – List only parent attributes on woocommerce admin atrributes page
I would like to add option on attributes page screen options, to filter out only parent attributes.
The main struggle is that I can’t even alter the query… I tried actions:
pre_get_posts but it looks like these are not suitable for taxonomy query.
public function prepare_items() – doesn’t have any hook to add more arguments…
Please point me to the right direction.
