/**
 * Represents the column-menu item for sorting TreeList columns.
 *
 * Render this component inside a [`ColumnMenuTemplate`](https://www.telerik.com/kendo-angular-ui/components/treelist/api/columnmenutemplatedirective) directive.
 *
 * To register the component as a known column menu item, set the [`ColumnMenuService`](https://www.telerik.com/kendo-angular-ui/components/treelist/api/columnmenuservice)
 * that the template passes to the `service` input of the `kendo-treelist-columnmenu-sort` component.
 *
 * @example
 * ```html
 * <kendo-treelist ...>
 *   <kendo-treelist-column field="ProductName">
 *     <ng-template kendoTreeListColumnMenuTemplate>
 *       <kendo-treelist-columnmenu-sort></kendo-treelist-columnmenu-sort>
 *     </ng-template>
