Hello.
Please explain how to use the «Section» feature. (see attachment)
I do not understand what to input in the «Object» and «Section ID» fields.  And for what purpose?

And why I need to choose «Section file»? What purpose of it.

Your explanations in the documentation are not enough. I still don't understand the logic of the «Section» feature.
Please explain in detail, with examples of each field. («Object», «Section, «Section file»)
Thank you in advance!
