I am working on a team site collection inside my sharepoint 2013 on-premises. and i am facing this issue which i thought sharepoint will provide out of the box, but seems it does not.
now i have a SharePoint Security Group named "software development members", and i want to define a site column of type "Person or Group" which will allow selecting a single user from the group or the group itself. so i tried the following settings:-
but this will only allows me to select from members inside the group and not the group itself. now if i change the Choose from to be All Users
this will allow me to select the "software development members" group, but i will be facing another issue that users can select any group or any user which of course i do not want to have!! so can anyone advice on this please?
