I was reading the solution presented on the other thread, but i guess the code shown unfortunately doesn't match with my target.
My point is, i'd like o to insert on the header menu a kind of new "Submenu" on my gridpanel scope.
Functionally i want to use this new submenu as a path to insert data into all column cells.
The data offered by the submenu should contain the same data presented as an option for insertion of individual cells.
I hope I have been clear on my explanation.
Is there a way to perform the described functionality?
Thanks in advance,
