Regarding filterable and groupable used together in a grid

[Deshna]

I want to use dynamic groupable and my aggregate value should be displayed only once..i.e if we group n no of columns the aggregate value displayed should be only once i.e the aggregate value of all the columns grouped..I am using normal javascripts and html for manipulation..


In filterable part I want to display the entire set of values present in that column i.e like a drop dowm menu...how to do that???

and when both filterable and dynamic groupable are used together how to get the aggregate value of the n filtered columns..
