Collapse groups in a summary view?
How do you collapse group rows in a summary view? Or to collapse a section in a pivot view? Is there anything like a tree control? This would seem like basic functionality for display of grouped data. For example, suppose I have a pivot view with a summary grouping on "Nation", like:
Nation
| Region | Total |
United States |
| 4,100,000 |
| Colorado | 3,000,000 |
| New York | 1,100,000 |
Canada |
| 2,000,200 |
| Alberta | 2,000,200 |
…and I want to be able to toggle the "United States" row to collapse it, hiding the detail of that section, like…
Nation
| Region | Total |
| United States |
| 4,100,000 |
| Canada |
| 2,000,200 |
| Alberta | 2,000,200
|
And then be able to expand it to see the detail again. Also be able to "expand all", "collapse all", as with a tree control? Is there anything like this in Zoho?
