Finally: version 0.3.0 with multiselect support is out
LiveSelect now accepts a new :mode option, which takes either :single or :tags as value. :single mode is the old single-selection mode you already know. :tags mode turns the component into a multiselect input with tags:
I didn’t simply call it :multiple because I envision new multiselect modes in the future with different flavors, for example using checkboxes in the dropdown.
As usual, all new elements (these includes the single tags as well as the box containing them) can be styled by passing the appropriate options.
And as usual, you can experiment with all the options by running the showcase app locally.
I hope folks who were waiting on the multiselect feature will be satisfied! 
Looking forward to your feedback. Cheers!
