In this article you will learn about Site Columns in SharePoint.
What is Site Column You often create columns directly in your SharePoint List or Library. But this column is different from SharePoint Site Columns. When you create a column inside List or Library, this column scope is limited to that particular List or Library. If you need the same column in another List or Library you will have to create again the same column for that List or Library. Here Site Columns comes in picture. Site Column provides reusable columns within Site Collection. In short Site Column belongs to all Lists and Libraries within site collection. Many site columns come with site Template when you create site collection. Still we need columns that are not available. Note: Site Column essentially uses in Content Types. Site Columns can be access across the site collections when you create Content Type Hub. We will discuss this in another blog. Let’s create site column.
