Can I save questions while creating them?

You can save.

[When creating with the question creation form] If you save while creating and set the public restriction to "private", it will not be displayed to members.
Also, if it is a question created in a folder, it will not be displayed to members unless the folder is assigned.


[When creating in text/Excel]                                                                                                                    After completing the problem
