Maybe the answer to my question is very simple, but i cant find out how to change the items that are shown in the mainbody GK GRID and the bottom I GK GRID.
By selecting the source, i can change the items, but i want to adjust them.
The bottom I GK GRID (source gk grid I) items are users but for example, i want to make it show brands or something.
Can somebody tell me how to do so?
Thanks (in advance
