When including dynamic product content in templates, it is typically not desired to show the same product multiple times. This situation can be handled automatically via an option in the Details pane for the Container, as shown below.
Which Products Are Removed
When utilizing the product deduplication feature, products will only appear a maximum of once within all dynamic grids that are used in the content. Further, if multiple products share a parent_product_id, only the first product will appear within the content.
For example, a template has a grid for cart abandoned products, and a second grid for recommended products. If Product A qualifies for both grids, it would only appear in the cart abandonment grid, because that grid appears first in the template. If Product B shares the same parent_product_id as Product A, then Product B would also be suppressed, whether it appears in the cart abandonment grid or the recommended products grid.
