​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ Nested Repeaters

Create nested repeaters in your form and integrate them into other lists in two minutes, using SPARK Forms Builder without the need to write a single line of code.

SPARK Forms Builder provides you a great controls such as Advanced Nested Repeaters, which is compatible with SharePoint 2019,2016, 2013 and Office 365 as well.​​

Repeaters represents repeating sections containing groups of controls that may need to be duplicated. A typical use is an expenses form where each row is an expense item. You only need to set up the controls once, and you will view them at runtime as one row, which can be replicated when users click "Add Item" icon in the repeater. In each column in the repeater, you can create a summary that performs various functions, such as counting the number of items or calculating the totals of values for each row. You can easily perform actions on the sections, like disabling or hiding the controls within each row.

With out-of-the-box SPARK functions, you can easily retrieve values from internal and external lists and represents (generates) them into a repeater at runtime. You can add row(s), delete row(s) to/from a repeater, you can show/hide "Add Item", you can show/hide Delete button, you can get number of rows in a repeater and much more. The designer can create unlimited number of nested repeaters, save their data to a column as an XML string structure, or through mapping them to other master - details lists.​
