 * Renders the fixed group header content. To define the fixed group template, nest an `<ng-template>` tag
 * with the `kendo<ComponentName>FixedGroupTemplate` directive inside the component tag. The template context is
 * set to the current component. To get a reference to the current data item, use the `let-groupName` directive.
