Virtualize component
Virtualize is a component in Blazor that will make sure that it only renders the components or rows that can fit the screen. If you have a large list of items, rendering all of them will have a big impact on memory.
The Virtualize component works just like a foreach loop.
<ul>
@foreach (var p in posts)
{
<li><a href="/Post/@p.Id">@p.Title</a></li>
}
</ul>
same as
<Virtualize Items="posts" Context="p">
<li><a href="/Post/@p.Id">@p.Title</a></li>
</Virtualize>
