We currently use grouping in the Kendo Grid, however the groups are always sorted alphabetically by the name of the group.
In our case, we want the groups to be sorted another way: an order value that corresponds to the group name.
To do this, it would be good if we could specify a comparison function, and have it take a object we provide (a map between the group name and order value).
We currently work around this by prepending a character to the group name to have it sort correctly (see screenshot). As you can see, it's not very appealing.
