When trying to use autocomplete, it falls short of what I would like to have. I presumed this to be on feature parity with MudBlazor offerings.

What I used before with mudautocomplete: label, value, style, reset value on empty text, coerce text, to string func, search func, required, required error, value changed, virtualize, max items. The way I use autocomplete box, is that user searches against a list of hundreds of thousands of elements, component querys against method, get's filtered reply that is displayed. When chosen, it binds the guid value, not the string. User also cannot submit their own option, only one from provided list. 

Telerik autocomplete box does not provide those features, what other workarounds are there besides running with Mudblazor for time being?
