columns.groupable Boolean|Object *(default: true)
If set to false the user will not be able to group the grid by this column (requires Grid groupable property to be enabled). By default all columns are groupable.
Example - disable grouping for individual column
<div id="grid"></div>
<script>
$("#grid").kendoGrid({
groupable: true,
columns: [
{ field: "name", groupable: false },
{ field: "age"}
],
dataSource: {
data: [
{ name: "Jane Doe", age: 30 },
{ name: "John Doe", age: 30 }
]
}
});
</script>
