Delete a notebook list without removing notebook

[fish92 0]

So some of my notebooks are grouped in a list, and somehow I wanted to ungroup them. But there is no way to move notebooks away from the list?

Any help will be much appreciated.

Do you mean grouped in a Stack?  If so, right click on the Notebook and select Remove from Stack.

There is, but you'll get more specific advice if you specify whether you're using Windows, Mac, Android, iOS, or the web client....
