It added the Sum at the top of each grouped item - you did not have to expand the item to see the sum.
I found JSON to be able to update the group headers but it only updates the text and uses the count feature not a sum feature. I am able to customize the footer on the Hours Worked Column to reflect other things besides just the word "sum" - such as color and other text, but I want to be able to have the sum be at the top of each group when it is collapsed like it is in the screenshot above. I am guessing it is something that needs to be done on the column rather than the item grouped. Does anyone have JSON that would do this?
Here is a screenshot of the list with JSON deployed where it formats the group header on what it is grouped on and the footer changed, but I can't seem to figure out how to make the footer the header:
So basically, I want to move the red Total Value up so it shows when the groups are collapsed, ie next to the 1 Test 1(s), 2 test 5(s), etc.
