How can you filter a people picker field based on a SharePoint group?
any further details on what you want to achieve?
it you restrict PP field/control to accept only users from a specific SP group it will do restrict possible inputs to the group members.
I'm not sure what further filter would you mean.
For me, I need to put a number of groups names into a dropdown list box ( group1 => id=19, group2=>id=19, group3=> id=20. Then when the value of the dropdown list box changes, update the value of the data-sharepointgroup on the people control so that the users being queried changes.
I basically need to assign a task to a list of people from one of the groups listed in the dropdown.
. I've toyed with use the _catalogs\users hidden list but that isn't working out too well. I can seem to get the secret hand shake on specifying a hidden list as an expression in the list property..
that's, unfortunately, not possible with nintex. people control doesn't support to change source user group at runtime.
what you could do at mosty is to add a separate people control for each group. then use formatting rules which based on dropdown selection show respective people control and hide all the others.
