Autocomplete to allow for multiple words

Autocomplete to allow for multiple words

I am new to this forum, so please forgive me if this has already been posted.

It would be great if one could specify a delimenator so that a fresh autocomplete list appears when one starts a new word followed by the delimenator, in the same string. This would work great for things like email addresses.

How could I go about contributing development to these controls?

Thanks for a great library!
