+ * Gravity Perks // Easy Passthrough + Nested Forms // Duplicate child entries on passthrough
+ * https://gravitywiz.com/documentation/gravity-forms-nested-forms/
+ * https://gravitywiz.com/documentation/gravity-forms-easy-passthrough/
+ *
+ * Experimental Snippet 🧪
+ *
+ * Installation Instructions: https://gravitywiz.com/documentation/how-do-i-install-a-snippet/
+ *
+ * Duplicate child entries when a parent form is passed through using Easy Passthrough.
+ *
+ * Configuring:
+ *  * Update $parent_form_ids to match the form IDs that need to have their Nested Form field child entries duplicated
+ *  * Update $parent_form_field_ids to include the Nested Form field IDs that should have their child entries duplicated
+ *
+ * As an example, this snippet is configured to duplicate child entries for Nested Form fields 4 and 5 in form 123.
