+ * Gravity Perks // Nested Forms // Auto-attach Child Entries to Parent when Editing via Gravity Flow.
+ * https://gravitywiz.com/documentation/gravity-forms-nested-forms/
+ *
+ * By default, when adding a new child entry to a Nested Form field while editing a parent entry via Gravity Flow, the
+ * child entry is saved to the session and will not be attached to the parent entry unless you click "Submit" on the
+ * workflow.
+ *
+ * Use this snippet to automatically attach the child entry to the parent as soon as the child form is submitted.
