I am trying group with the angular example here
http://dojo.telerik.com/@ggkrustev/ihUci
my datasource is set up the same schema but I am binding like this.
<select id="ddl" kendo-drop-down-list style="width:300px" k-filter="'contains'" k-data-source="Controller.Data" k-options="Controller.options"></select>
Is there a way to group by if I am not grouping in the datasource like in the link?
