filterable.operators Object

The text of the filter operators that are displayed in the filter menu.

In multiple TreeLists, you can override the filterable options of the FilterMenu before the TreeLists are initialized. Then, the new filter options will be available for all TreeLists without further configuration.

Example - overriding the filterable options in multiple TreeLists

<h4>TreeList One</h4>
<div id="treeList1"></div>
<h4>TreeList Two</h4>
<div id="treeList2"></div>

<script>
  kendo.ui.FilterMenu.fn.options.operators.string = {
    eq: "Equal to...",
    neq: "Not equal to..."
  };

  $("#treeList1").kendoTreeList({
    columns: [
      "lastName",
      "position"
    ],
    filterable: {
      extra: false
    },
    dataSource: {
      data: [
        { id: 1, parentId: null, lastName: "Jackson", position: "CEO" },
        { id: 2, parentId: 1, lastName: "Weber", position: "  VP, Engineering" }
      ]
    }
  });

  $("#treeList2").kendoTreeList({
    columns: [
      { field: "lastName" },
      { field: "position" }
    ],
    filterable: {
      extra: false
    },
    dataSource: {
      data: [
        { id: 1, parentId: null, lastName: "Jackson", position: "CEO" },
        { id: 2, parentId: 1, lastName: "Weber", position: "  VP, Engineering" }
      ]
    }
  });
