To get started, go to the Dynamic Product Groups and click on “Add dynamic product group”.

Give it a name and enter the following values. In the last field, set it to “Yes” and choose which attribute you want to filter by.

Choices:
For now, I’ll choose Eco. This could already be enough, but you can also add an extra criterion, like a category:

Then click on “Add AND condition” and fill in the desired data.
It’s now set to “Is equal to any of”, so you can say you want all eco products from the following categories, and not just one.
Once you save, you’ll have a Dynamic Product Group with eco products from the categories Suitcases & Trolleys, Drybags, and Document folders. Once you try it yourself, you’ll see there’s much more possible than what we’re showing here.
Linking a dynamic product group
You can link a dynamic product group to a category or to a product slider. You can do this in the following way.
Linking to a category:
Go to 'Categories' and create the desired category. Then link the dynamic product group to this category. After you have done this, you need to clear the cache. After that, the category will also be visible on the front end.

If you want to link this to a product slider, you need to adjust the same settings within the product slider as in steps 7 and 8.
