This article instruct you how to hide a table row by filtering the related list or add condition to the row.
Hide the row using If attribute
In some case, you may want Documill Dynamo to process all the line item data, but not to show them in the table. Thus, instead of adding the where condition in relatedList tag, you can add a If condition in the Row element.
Click to the table and select Row in the breadcrumbs. The selected Row should be the element where you mapped relatedList data.
Select Tag in the right pane, then select Attributes tab
Select the "..." icon next to If attribute to add the condition you want to use. The Data Source should open the list of fields in from the related list.
