Prevent duplicate selections in multiple mode

[DavidStirling]

In the "multiple" examples it's currently possible to select the same option repeatedly. Ideally there'd be a simple way to drop selected items from the options list. Apologies if this already exists and I've just missed it!

The kitchen sink has an example of disabling picked options (you could also filter them out from the available options if you prefer).

  const disable = (value) => selectedValues().includes(value);

Let me know if that helps!

That'll work for my case, much appreciated!

For ease of use I'd still suggest that this behaviour be a setting if possible.
