• Collapsed Rows (E)
  Choose to see collapsed rows as the number of elements it contains, the JSON representation (abridged), or nothing (blank).
• Scope (F)
  Choose if you want to see the entire row, all columns belonging to the same root column group, or all columns belonging to the closest singular column group. If you choose the closest group, the actual group varies with the structure; the root of the tree will be the closest column group that is not part of an array. In the picture below, the tree starts at the root column (location).
• Auto Expand (F)
  Choose to automatically expand the tree to the level of the grid cell you selected.
• Auto Filter (G)
  Choose to filter on the selected cell, the tree will only show the cell you selected. If the cell is part of an array, you will see all occurrences of the cell.
