I need the after click and select option in scroller

[juanitourquiza]

I have a virtual-scroller working but it's necessary for me when the user select of item. The item changes the color similar to the action routerLinkActive and this item has a selection while the user selects another item.

This is the code:

<div #scrollingBlock>
    <virtual-scroller #scroll 
        [items]="items" 
        [parentScroll]="scrollingBlock"
        [bufferAmount]="100">
        <div class="space">
            <ng-container *ngFor="let item of scroll.viewPortItems"> 
                <ng-container *ngTemplateOutlet="listViewItemTemplate; context: {$implicit: item}" >
                </ng-container>
            </ng-container>
        </div>
    </virtual-scroller>
</div>

Does someone have an idea?
