Add a field group list to a form to store the values of a list of related fields in a page list data structure. For example, you can capture a list of names and addresses from your work history in the Previous Employers field group list.
In the Explorer panel, click Cases, and then click the case type that you want to open.
On the Life cycle tab, click an assignment or an approval step.
Click Configure view.
Click + Add field.
In the autocomplete field that is displayed, enter a unique label.
Do not use px, py, or pz prefixes in a label because they are reserved.
From the first list that is displayed, select Field group (list).
Optional: Add fields to the field group list, by reusing properties in an existing class or configuring an advanced data reference.
Click the Gear icon.
Clear the value in the Data type field.
Press the Down Arrow key and select the name of a class.
Click OK.
The properties in the class are displayed as fields on the form. You can reorder or remove them as needed.
Tip: Follow these steps when the data reference is sourced by a data-page list that accepts parameters.
Click the Gear icon.
Clear the value in the Data type field.
Press the Down Arrow key and select the name of a class that has at least one data-page list defined.
Select the Is this a data reference? check box.
In the Select the source list, select the name of a data-page list.
Enter values in the fields that are displayed in the Parameters section.
Click OK.
Click + Add field to [repeating field group].
Configure the single-value field.
For more information, see: Adding a single-value field to a form
Note: You cannot reuse the single-value fields that you define in a field group list on other forms.
Click Submit.
After you add a field group list to a form, you can reuse the field group list because it is part of the data model for your case type.
Values from the field group list are stored in a page list property in the [Your organization]-[Your application name]-Data-[Repeating field-group name] class.
