My grid has "groupable: true", however only ​selected columns are groupable:
columns: [
{ field: "todo", groupable: false },
{ field: "author", minScreenWidth: 768 } ]
"Trouble" is the "grouping drop area" is visible on any screen size, but the groupable columns are not shown on small screens.
How can I control visibility of the "grouping drop area" based on screen size?
A "groupable.minScreenWidth" property would be great.
