Hello? I was watching your video and practicing NB designer.

But there's something I don't understand.

Tell me about this part.


I saw the video [How to create Component in Product Builder of NBDesigner?].

In the video, after you have finished setting options,
If you log on to the site, you'll see the Customize button.
The button opens a new window.
When you press the right menu in that window, the menu on the left changes.

But after I've copied it like a video,
[customize] No buttons, no new windows.

Why not?
