* Represents the Kendo UI for Angular TreeList column-menu item for chaging the visibility of the columns. [See example](slug:columnmenu_treelist#toc-column-chooser-item).
*
* Place this component inside a [`ColumnMenuTemplate`]({% slug api_treelist_columnmenutemplatedirective %}) directive to enable the feature.
* Set the [`ColumnMenuService`]({% slug api_treelist_columnmenuservice %}) and `column` inputs using the values passed by the template.

* @example
* ```html
* <kendo-treelist [columnMenu]="true" ...>
* <ng-template kendoTreeListColumnMenuTemplate let-service="service" let-column="column">
* <kendo-treelist-columnmenu-chooser [column]="column" [service]="service">
