First, Im looking for the ability to customize the dropdown button on the toolbar. I found this example https://www.telerik.com/kendo-angular-ui/components/toolbar/custom-control-types/ but it appears to be out of date from the latest kendo ui libs and doesn't work in angular 9. I mean an exact copy of this example running Angular 9.0.0, results in no custom button.
So close on so many of these things but so far from being a useful library when custom matters in business apps.
It should not be that difficult to provide a custom template for the dropdown list.
