Vue.draggable: Transition-group not working

[ZalgirisKaunas]

I am trying to do the same transition effect as in this fiddle:

I can't understand why it's not working in my fiddle:

there is no tranistion classes in your fiddle

[David-Desmaisons]

In fact your draggable component is not using nor a :list nor a v-model binding

[jr-suraj]

At first, I used :list and v-show and it worked well, But changed v-show to :class then transition is gone. Like this,

:class="{hide:emp.show}"
:list="emp.children"
