Using $refs to set a dropActive prop is not ideal as $refs is not reactive.
I would suggest emiting an event.
Simplest way to do it would be to add this.$emit('dropActive, true) near the places where this.dropActive = true is used in the source code and this.$emit('dropActive, false) where this.dropActive = false is used.

Should also solve the issue 254.

Thank you for your attention!
