my goal is create a customizable reactJS pivot table widget by creating new app on board with SDK functions and setting widget.
I didn’t find on monday support how to create pivot table widget with open source react js.
Thank you for helping me !
Hello there @Baidris and welcome to the community!
I am not sure about the pivot table and how monday could help you with that part, but regarding the view, you can create a board view as explained here and then in there you can show whatever content you want to show 
If you create the UI and functionalities of the pivot table, you can display it there.
Please let me know if you have any questions!
Cheers,
Matias
