WooCommerce - Percentage Discount in products categories widget

Question

I need to custom the output of Woocommerce Products Categories Widget showing the percentage discount for that category (Discount_Price*100/Standard_Price).
I can easily create a function that takes from the first product of that category:

• Discount Price
• Standard Price

and calculate the percentage discount, but I don't know how to show it in the output of the widget like this:

• First Category (50% discount)
• Second Category (30% discount)

Can you help me?
Thanks

Looks like the only entry point is the filter woocommerce_product_categories_widget_args . The output is done via wp_list_categories and I guess you'll have to do a custom walker to achieve what you want. Or duplicate the widget code and make your custom one.
