With multicheckbox i get the following console error when checking items, clicking save sends an empty selection:

TypeError: this.checkedItems.push is not a function
    at a.onChange (multicheckbox.vue:39:1)

    at HTMLInputElement.o._wrapper (vue.esm.js:7609:1)

With multiselect i get the following console error on page load and no input is rendered:

Hey @noplanman
I'm getting the same error here, however... in version 1.0.15 this seem to be working still.
You have the same thing?

This project seems to be abandoned, or... at least left broken for some time now.

@miriksbm I'll take a look and see.

Yes, unfortunately it has been abandoned. I've forked it and maybe I'll add / fix some things, not sure yet.
