Did you test it after changes ? Hope the if (attr) is fine in most case, thanks for you work.

Yes, tested and works as expected. Thank you.

On implementing on a live site I noticed the Bloodhound engine returns multiple results for 'Size : S' but not 'Size : M'. Have changed result.length == 1 to result.length >= 1 and first result in array is used. Also fixed issue from original code that reported an error when removing invalid tokens. As the new code has the 'invalid' class I have added a check for that. Apologies for not noticing this initially.
