+ * Gravity Perks // Populate Anything // JetEngine Repeater Mapper
+ * https://gravitywiz.com/documentation/gravity-forms-populate-anything/
+ *
+ * Populate all rows from a JetEngine Repeater into a choice-based field.
+ *
+ * Instructions
+ *
+ * 1. Enable "Populate choices dynamically" on any choice-based field.
+ * 2. Select the "Post" object type.
+ * 3. Apply any desired filters to determine which post(s) should have their repeater data populated.
+ * 4  Use the "Choice Template" to map each choice property to a repeater subfield. To do so you will need to:
+ *
+ *    a. Select "Custom Value" from the "Value" dropdown and specify the repeater name and desire subfield like so:
+ *       "repeater_name/subfield_name".
+ *    b. Repeat for each Choice Template property (e.g. Label, and Price, if applicable).
+ *
+ * 5. Add the "gppa-jetengine-repeater-mapper" to the field's CSS Class Name setting.
