columnMenu.filterable Boolean (default: true)

If set to true, the column menu will allow the user to filter the TreeList. By default, if filtering is enabled through filterable, the column menu allows the user to filter.

Example - disabling column menu filtering

<div id="treeList"></div>
<script>
  $("#treeList").kendoTreeList({
    columns: [
      { field: "name" },
      { field: "age" }
    ],
    filterable: true,
    columnMenu: {
      filterable: false
    },
    dataSource: {
      data: [
        { id: 1, parentId: null, name: "Jane Doe", age: 22 },
        { id: 2, parentId: 1, name: "John Doe", age: 24 }
      ]
    }
  });
</script>
