Using Repeatable Sections to Create Child Records on iOS
Adding child records to a parent record on a mobile device is no more difficult than creating any other record. The repeatable field will be shown in the parent record as if it were a normal section with the drill down option selected section.
Once in the repeatable section of a record, you can add child records in the same way as you would with a conventional record. There is a list view and map view options, a search box, and a create record icon. When you are finished adding child records to the parent record tap on the back arrow and then tap the save button to save the child records added.
