How to fill out just one list with vuedraggable? - vue.js

Question

I am using the following library
https://sortablejs.github.io/Vue.Draggable/#/custom-clone
specifically using the example:
https://github.com/SortableJS/Vue.Draggable/blob/master/example/components/clone-on-control.vue
<template>
<v-container fluid>
<div class="row">
<div class="col-3">
<h3>Draggable 1</h3>
<draggable
class="row wrap fill-height align-center sortable-list"
style="background: red;"
:list="list1"
:group="{ name: 'people', pull: pullFunction }"
#start="start"
>
<v-card class="list-group-item" v-for="element in list1" :key="element.id">
{{ element.name }}
</v-card>
</draggable>
</div>
<div class="col-3">
<h3>Draggable 2</h3>
<draggable class="dragArea list-group" :list="list2" group="people">
<v-card class="list-group-item" v-for="element in list2" :key="element.id">
{{ element.name }}
</v-card>
</draggable>
</div>
</div>
</template>
<script>
import draggable from "vuedraggable";
export default {
components: {
draggable
},
data(){
return {
list1: [
{ name: "Jesus", id: 1 },
{ name: "Paul", id: 2 },
{ name: "Peter", id: 3 }
],
list2: [
{ name: "Luc", id: 5 },
{ name: "Thomas", id: 6 },
{ name: "John", id: 7 }
],
controlOnStart: true
}
},
methods:{
pullFunction() {
return this.controlOnStart ? "clone" : true;
},
start({ originalEvent }) {
this.controlOnStart = originalEvent.ctrlKey;
}
}
}
</script>
What I need to do is fill only a list, that is, from Draggable 1 to Draggable 2, currently it is from Draggable 1 to Draggable 2 and from Draggable 2 to Draggable 1 but I don't need it that way.
Thank you
