使用Quasar，在鼠标事件时，显示列表

<template>
  <div>
    <q-list>
      <q-item v-for="item in items" :key="item.id">
        {{ item.name }}
      </q-item>
    </q-list>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
        { id: 3, name: 'Item 3' }
      ]
    }
  }
}
</script>

<template>
  <div>
    <q-btn @click="showList">Show List</q-btn>
    <list-display v-if="showingList"></list-display>
  </div>
</template>

<script>
import ListDisplay from './ListDisplay.vue'

export default {
  components: {
    ListDisplay
  },
  data() {
    return {
      showingList: false
    }
  },
  methods: {
    showList() {
      this.showingList = true
    }
  }
}
