This is not a free plugin.

You are not correct! ??

Go to your widgets page and add the YITH widget to where you want it to go and hey-presto, it worked perfectly, right out of the box, giving a perfect sidebar woocommerce product categories menu.

You select the options of how you want the menu to work when you add the widget. eg. show sub-categories, etc

It’s a great plugin and so happy I found it ??
