Problem: I would like to use custom CSS classes to create toggle sections in my filters, but the custom CSS classes I have applied to filters are being removed when filters are updated.
Solution: Use the JavaScript event js_event_wpv_parametric_search_form_updated to hook into the filter update process and manage your CSS classes after that hook has been triggered.
3) Dashboard-> Toolset-> Woocommerce Views:
Choose the options you want, then "Save all Settings", and test again.
It should be able reset all "Toolset WooCommerce Blocks" plugin settings, and resolve the PHP notice problem.
