I used to be able to collapse and expand groups by toggling something (I can’t remember what it looked like)
But now I can’t:
It seems that the “little arrow glyph” as mentioned in the manual is no longer present!
If this is broken, please fix it.
It’s because the Group column is turned on. If you turn it off, groups will be indicated by headings between each group, which can be collapsed.
Thank you. I did referred to the ‘Sorting and Grouping’ page of the manual.
It seems there are 2 ways to group: With the Group column, and without. But in my opinion, that is not at all clear in the manual.
