columns.menu Boolean

If set to true, the TreeList will display the column in the column menu. By default, the column menu includes all data-bound columns, that is, the ones with a set field option.

Example - hiding a column from the column menu

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