Create powerful parent-child relationships using TekDog's subform control. Please refer to the following quick start guide for the configuration of the TekDog Subform Control. The Subform Control creates parent-child relationships between SharePoint lists using magic and a little code. The Subform Control requires that you have two data sources: a parent and a child. As an example, if we were working with Expense Reports we may have two lists, one for Expense Reports (Parent) and another for Expenses (Child). You cannot have expenses without an expense report. This relationship between a parent and a child can be accomplished with our Subform Control.
Step 1: Create your Lists
You should have 2 lists, a parent list and a child list. Example: Expense Report(Parent) and Expenses (Child).
Step 2: Create a new Nintex Form
Navigate to your "Parent" list and create a new Nintex Form.
Step 3: Select TekDog Subform
From the Form Controls selection on the left of your designer, select TekDog Controls, TekDog Subform.
