It would be nice to be able to configure the grid in a way that when I collapse a group, the lines it was occupying are then filled up by the results from the following pages.
Kendo Grid currently only minimizes the results of the current page. It ignores the pageSize config we have set, not bringing more items to occupy the number of lines we have configured.
Here are some screenshots I took from the DevExpress grid. There you can see that the column year is grouped and initially the years 90 and 91 are expanded. When I collapse the year 90, the results from the year 91 fill up the space the other group was not using anymore.
