Hello,

In order to show products in the sidebar, create an HTML block and insert the Product Grid element. You can configure showing the bestsellers from a certain category. https://xtemos.com/docs/woodmart/faq-guides/product-grid-carousel-element/

Then you can add the HTML block widget into the proper sidebar in Appearance > Widgets.

In order to show the products as per your configuration in the content. You need to insert the Product Grid element right into the content.

Best Regards
