Does anyone know how to create a group?

[yoochris]

I dont know how to get the “target” in vue。I written it like this <vue-moveable :target="document.querySelector('.target')" v-bind="moveable" @dragGroupStart="onDragGroupStart" @dragGroup="onDragGroup" >{{targets}} </vue-moveable>, But it didn't work。Can someone help me? thanks a lot.
