Better UX experience for deleting multiselect values
Is there any way to customize the selected "tag" value in the multi-select mode so I could just click on it's 'x' small icon to remove it from the selected list? This is how Select2 and react-select work. I think it's more intuitive for new users.

you can do that by implementing the renderValue / renderOption props, see here (http://furqanzafar.github.io/react-selectize/#/?category=multi&example=custom-filtering-and-rendering)
Maybe this will be useful to others. Example at http://cdpn.io/BQQdWG
It would be useful to have a property in MultiSelect such as dismissibleTags that automatically generates tags with the close icon on each tag, as in my example. This is a common feature of tags and it would be nice for it to be generated for users so they don't have to go to the trouble of creating a custom renderValue function, css, etc.
Consider this a feature request.
The original selectize js library has simple examples which let you click to select a tag in the multiselect.

Surprised react-selectize doesn't support that bit out of box.
@twig tagging & item creation is supported http://furqanzafar.github.io/react-selectize/#/?category=multi&example=tags
Yeah but you can't select them and then press delete like in the original selectize examples
