I'have implemented such a widget in django-formset <https://django-formset.fly.dev/>. It just hides (removes) the selected options which have been filtered out. Otherwise, filtering by muting options, wouldn't have the desired visual effect.
Please note that in order to implement this feature, I used three <select multiple> elements, two of them visible (the left and right one) and one hidden, which contains the currently selected options, even if filtered. A nice side-effect of this architecture is, that it allows autocompletion for long source lists, and in addition, undoing and redoing a selection.
