或嵌套列表-Vuetify

我正在尝试创建具有三个以上嵌套级别的嵌套列表。当我在v-list的子项中放置项的子项对象时,它什么也不显示。

甚至可以在vuetify中创建这样的嵌套列表吗?如果没有,该问题有什么解决方案?

<div>
  <v-list v-for="(powerPlant, i) in powerPlants" :key="i">
    <v-list-group
      prepend-icon="fas fa-bolt"
      value=""
     >

      <v-list-tile slot="activator">
        <v-list-tile-title>{{powerPlant.name}}</v-list-tile-title>
      </v-list-tile>

      <v-list-group
        no-action
        sub-group
        value="true"
        v-for="(generator, i) in generators" :key="i"
      >
        <v-list-tile slot="activator">
          <v-list-tile-title>{{generator.name}}</v-list-tile-title>
        </v-list-tile>

        <v-list-tile
          v-for="(option, i) in options"
          :key="i"
        >
          <v-list-tile-title v-text="option[0]"></v-list-tile-title>
          <v-list-tile-action>
            <v-icon v-text="option[1]"></v-icon>
          </v-list-tile-action>
        </v-list-tile>
      </v-list-group>
    </v-list-group>
   </v-list>
  </div>

如果有另一种方法可以使用Vue.js而不使用jQuery创建大型嵌套列表,我想学习。

对不起,您无法解释清楚。这样,一个已发布的列表可以达到3个级别,但是我不能再像4个或5个级别了。

我通过嵌套v-list这样解决了这个问题:

<v-list>
    <v-list-group v-for='node in nodes' v-model='node.active'>
        <v-list-tile slot='activator' @click=''>
            <v-list-tile-title>{{node.text}}</v-list-tile-title>
        </v-list-tile>
        <v-list class='py-0 pl-1'>
            <v-list-group v-for='child in node.children' v-model='child.active'>
                <v-list-tile slot='activator' @click=''>
                    <v-list-tile-title>{{child.text}}</v-list-tile-title>
                </v-list-tile>
                <v-list class='py-0 pl-2' v-for='grandchild in child.children'>
                    <v-list-tile>
                        <v-list-tile-title>{{grandchild.text}}</v-list-tile-title>
                    </v-list-tile>
                </v-list>
            </v-list-group>
        </v-list>
    </v-list-group>
</v-list>

这可以任意深入。实际上,我需要一个无限嵌套的列表,所以我创建了这个简单的递归组件:

<template>
    <v-list>
        <template v-for='node in nodes'>
            <v-list-group v-if='node.children && node.children.length' v-model='node.active'>
                <v-list-tile @click='' slot='activator'>
                    <v-list-tile-title>{{node.text}}</v-list-tile-title>
                </v-list-tile>
                <node-list class='py-0 pl-3' :nodes='node.children'/>
            </v-list-group>
            <v-list-tile @click='' v-else>
                <v-list-tile-title>{{node.text}}</v-list-tile-title>
            </v-list-tile>
        </template>
    </v-list>
</template>

<script>
export default {
    name: 'node-list',
    props: ['nodes'],
}
</script>
