The Magento 2 Dynamic Category extension provides a flexible filtering mechanism for filling the dynamic categories of your store with the exact products you need. This is done through a
set of conditions that allow you to precisely specify the product attributes that will be used to filter out items from the store's catalog.
In addition to default Magento attributes that can be used for filtering products out, the Dynamic Category extension provides several additional attributes. One of those attributes is the
source of the products. To filter the items by source, you can use the conditions such as the source of the product is/is not the specified source. The source which has to be a filter can
be chosen from a drop-down menu during the condition creation.
