Teleken Kendo Grid與Kendo Treeview編輯器模板的內聯編輯

Question

我有一個內聯編輯的劍道網格。 應該對字段之一進行編輯，以從列表中選擇一個元素，但是該列表必須具有層次結構（最好能夠過濾該列表）。 我當時在考慮使用劍道樹視圖作為該字段的編輯器，但是我還沒有找到實現此目的的任何方法。 我嘗試制作一個自定義編輯器模板（使用columns.Bound(s => s.FieldId).EditorTemplateName("_TreeEditorTemplate") ）來呈現樹視圖，但是樹視圖不是輸入，並且是不可選擇的。 我還考慮過使用kendo dropdownlist並在其中包含樹的編輯器，但是kendo當前不支持此編輯器。 有任何想法嗎？？？

您是否在Kendo網站上查看了示例： https : //docs.telerik.com/kendo-ui/controls/data-management/grid/how-to/Editing/use-treeview-as-grid-editor

 <div id="example">
        <div id="grid"></div>

        <script>
            $(document).ready(function () {
                var crudServiceBaseUrl = "//demos.telerik.com/kendo-ui/service",
                    dataSource = new kendo.data.DataSource({
                        transport: {
                            read: {
                                url: crudServiceBaseUrl + "/Products",
                                dataType: "jsonp"
                            },
