Compatibility with select2

Thanks for using the module!

How to implement non-standard input types is documented in the readme.

Sorry, but this is wrong. This error is not related to no standard input. By definition, a multiple select can be multiple=multiple or only multiple both are right. The path is to allow and accept both.

Ah I see. Sorry, I was confused by the issue description and the mention of Select2.
