Jeff29 on "[Plugin: WooCommerce - excelling eCommerce] where can I add the + - option in the add to cart button"

On the woocommerce screenshots page link below, I don't see in the setup where I can add a +- option in the add to cart button. Look at the 5th screenshot.

I don't see where this can be added in the settings tab.

If anyone can profer, I'd be grateful.

Thanks
