Okay -- admitted SharePoint newb here; apologies in advance, as I've been searching for 2 weeks to find a solution to this and SharePoint is not letting me find an answer.
We're using Office 365 (SharePoint Online), and I have a Site Structure like this:
123 Project 1
456 Project 2
789 Project 3
Projects is a subsite of the base site, then project 123, 456 and 789 are subsites of Projects.
We have projects that are active and projects that are closed/complete. I'd love to add a column/field on the Subsite that shows "Project Status" so we can search/filter by open projects in showing the content in various views. I can't seem to find a way to do this at all through the user interface. I saw one method that MIGHT work through a REST API, but couldn't find proper documentation on how to do it either.
Appreciate any and all assistance!
