* Represents the column-menu item that lets you lock or unlock columns.

* Render this component inside a [`ColumnMenuTemplate`]({% slug api_treelist_columnmenutemplatedirective %}) directive.
*
* To register the component as a known column menu item, set the [`ColumnMenuService`]({% slug api_treelist_columnmenuservice %})
