I am Trying to add a drag and drop functionality for the approvers / reviewers, is this something possible through standard Nintex form? I am using standard nintex form people group with repeating section, but i cannot move them in up or down order.
I'm not sure I understand what you are attempting to do with approvers. You mentioned drag and drop, but that functionality doesn't exist at the form level during edit or new mode. We only have the drag and drop for design time.
What are you really aiming to do?
We used the following method:
However this still moves the approver one row down and if an approver exist then they need to be removed manually:
I wanted to achieve similar functionality to something i saw in another application, where a uses can be added on button click and can be moved around. Hopefully you can assist.
Unfortunately that is not something supported by our product. Its also a limitation of the people picker control which is confined to how SharePoint will interpret the name and ID of the user being entered. I do get what you are looking for and the repeating section would be the only way to get close to that style of functionality.
