This extension is terrific, but I have a couple of issues that I can't seem to solve. I'm brand new to extJS so please excuse my novice status.
In a multi-grouped grid, is it possible to have a column that is a calculated percent of the group parent. I.E. If group A has 5 children, child one is 4 percent of total, child 2 is 55....etc, etc. This data would obviously have to dynamically change as the groupings were dynamically changed.
Can I sum the store to get a global total for the entire grid. So far storeName.sum('fieldName') has yielded me nothing. Is there a trick to it using the multiGroupedGrid?
