I am currently using the C1FlexGroupPanel which works very well for dragging/dropping groups. The problem I currently have is that I’d like 1 single row at the top of my grid that shows the Sum of each column. However, I do not want this to be a grouped row because I don’t want the grid to always be grouped.
Essentially I want to create a top frozen row that behaves like a grouping row in terms of showing aggregates, but isn’t a grouping row that can be collapsed or removed.
