columns.filterable.multi Boolean (default: false)

Use this option to enable the MultiCheck filtering support for that column.

If you have enabled the columns.multi option and your Grid uses serverPaging (or ServerOperations(true) when using the MVC wrappers) you will need to provide columns.filterable.dataSource. Otherwise, a negative impact on the performance could be observed.

Example - enable checkbox filtering support.

<div id="grid"></div>
<script>
$("#grid").kendoGrid({
  columns: [ {
    field: "country",
    filterable: {
        multi:true
    }
  } ],
filterable: true,
  dataSource: [ { country: "BG" }, { country: "USA" } ]
});
</script>
