Allow defining buttons in ButtonGroup component using NgTemplateOutlet:

  <kendo-buttongroup>
    <ng-container *ngTemplateOutlet="buttonsList"></ng-container>
  </kendo-buttongroup>

  <ng-template #buttonsList>
    <button kendoButton size="small">Button 1</button>
    <button kendoButton size="small">Button 2</button>
    <button kendoButton size="small">Button 3</button>
  </ng-template>

So far, the ButtonGroup doesn't appear when using this markup.

Hi team,

Currently, the ButtonGroup component supports two selection modes - single and multiple. 

However, there is no option for restricting the selection to a certain number of selected buttons (like having multiple selection but restricted to some number, like [maxSelected]="2" which will allow selecting max 2 buttons at a time).

Hello Telerik Team,

I would like to propose a feature request: currently, the <kendo-buttongroup> is not keeping track of toggled button/s, so it would be a good idea to implement this. My solution right now is 

<kendo-buttongroup class="view-mode-group"
    selection="single"
look="flat">
<button class="group-button"
kendoButton
(click)="onChangeViewMode(0)"
[toggleable]="true"
[selected]="isModeSelected$(0) | async">Imported Messages
</button>

Support for ButtonGroup in reactive forms to select a sinlge value. It would be great if it would work with typescript enums.

I need to set the initial state of a button group!  If I am using a buttongroup to represent a value, then how do I set the initial state?!  

How was this not thought of??
