ListBox - Multiple - Order by Selected?

Radzen.Blazor Components

I need to be able to selected multiple items from a List so the ListBox is perfect. The only issue I've noticed is that if I have a list of say 30 items, and 3 are checked, there's no way of knowing which items are selected except to scroll through the entire list because the Order of the List is whatever the order of the Original Lookup list

I'm looking at ways to sort the Lookup based on the contents of the SelectedValues list but lo luck so far.

I've figured it out, thought I'd share.

List<CategoryLookup> _categories;
private List<int> _selectedCategories = new List<int>() { 1, 15, 16 };

protected override async Task OnInitializedAsync()
{
    _loading = true;

    var c = await CategoryService.Lookup(ClientId);

    _categories = (from n in _categories
                  let i = _selectedCategories.IndexOf(n.Id)
                  orderby i == -1 ? _categories.Count : i
                  select n).ToList();

    _loading = false;
}
