It's not clear how to display a light blue preview line in a list when dragging items in a sortable list. It's not clear in the docs or examples.

In the examples section, both the pages and tree examples at the bottom have preview lines but its not clear at all how to create that.
I want to display a horizontal preview line similar to notion when you drag items around. Has anyone managed to do this?
