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 with significant control such as Advanced Nested Repeaters, which is compatible with SharePoint SE,2019,2016, 2013 and Office 365 as well.
Repeaters represent repeating sections containing groups of controls that may need to be duplicated. Typical use is an expense 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 the "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 the Delete button, can get the number of rows in a repeater, and much more. The designer can create an unlimited number of nested repeaters, save their data to a column as an XML string structure, or map them to other master - details lists.
