I have a form in SharePoint Online that has four fields - User Name, Job Title, Department and Office. The User Name field is a people picker field. I want people to select a person using the people picker field and then the other three fields automatically populate with the details for the selected user. At the moment I'm editing the form using InfoPath.
I want to do this in the simplest way possible with as little coding as I can get away with. I'd be grateful if someone could give me any pointers with this, as I thought it was going to be straightforward but it is proving more difficult than first thought.
Thanks in advance for your help.
