It is very typical to render a list of items and display a total row at the bottom of the table. An example in the UI Gallery called 'Table with total rows' demonstrates how to implement such UI using the optimized and legacy tables as well as using a repeating dynamic layout.

The example showcases how to edit the data using a legacy table but does not provide any example of how to achieve a similar functionality using an RDL

The attached RAP replace the RDL example and makes the RDL editable - It also showcased how the group can be expand / collapse and how to implement group level action like 'clear quantity'

Important note: This functionality is delivered 'AS IS' - it has been implemented on Pega 8.8 but will likely need code updates to work with newer version of the Pega Platform. This code has not been tested for accessibility compliance and will require more work to be fully accessible.

to use this example, import the attached RAP, add the ruleset RDLTotal:01-01 to your app and reopen the UI Gallery and navigate to the Table with total row example
