How do I add a divider line to my Experience?
To add a divider line to your Experience, start by creating a new Experience or editing an existing Experience. On the Experience screen you’ll see a dropdown menu with all the different types of content you can add.
Click into that dropdown menu and select Divider Line.

There are no options for a Divider Line (other than Sort#), so the only thing to do is to click the Save button at the bottom.
