Select2: How to remove instead of gray out item from dropdown when its selected

[Exerlol]

Hey, first of all, gr8 plugin...I used select2 3,4,1, and in that version, when you select item, it was removed from drop down...now its just grayed out...Is there a way to remove it instead of gray it out? Thanks in advance

There's a classic theme that you can use you get back then old theme, which includes removing the gray background for selected options.

You can also just hide the selected options with

.select2-results__option--highlighted[aria-selected=true] {
  display: none;
}

I tried this but it doesnt seem to work well.
This one worked well for me -
.select2-results__option[aria-selected="true"] {
display: none;
}
