Global Columns / Content

Global columns allow you to create content that is automatically updated on various pages immediately. To do that, go into the Column Settings (go with the mouse on top of a column):

Then at the bottom of the column settings, you will see the checkbox for creating a global column:

From the drop-down, you can select an already created global column or the option to create a global column from the selected one.

That's it; now, all the content in that column used in other columns will always be in sync (unless you remove the global column option for a specific column).
