I have a menu listing all of my products categories in Woocommerce. I need to add an attribute data-relation to each <li> tag and the value for each one would be the ID of the category.

I success to do it for the <a> tag. Does it exist a filter for <li>?

Here is the PHP filter function:

function category_menu_id_attribute ($atts, $item, $args) {
  $atts['data-relation'] = $item->object_id;
  return $atts;
  }
add_filter('nav_menu_link_attributes', 'category_menu_id_attribute', 10, 3);

Thank you for the help.
