columns.filterable Boolean|Object (default: true)

If set to true and if filtering is enabled for the entire Gantt, a filter menu will be displayed for this column. If set to false, the filter menu will not be displayed. By default, a filter menu is displayed for all columns when filtering is enabled through the filterable option. Can be set to a JavaScript object which represents the filter menu configuration.

Example - disable filtering

<div id="gantt"></div>
  filterable: true,
  dataSource: [
      id: 1,
      orderId: 0,
      parentId: null,
      title: "Task1",
      start: new Date("2014/6/17 9:00"),
      end: new Date("2014/6/17 11:00")
      id: 2,
      orderId: 1,
      parentId: null,
      title: "Task2",
      start: new Date("2014/6/17 12:00"),
      end: new Date("2014/6/17 14:00")
