循环遍历，怎样添加其他非文本内容

经历的少，竟然只知道，循环遍历中，数组中写的是文本，如果要添加图片，按钮，竟然慌了，细细一想，可能答案就在我自己的问题中。“如果。。。如果。。。”对吧？答案就在此,使用if就解决了，键值对多添加一个内容就可以了，图片url,按钮btn

<v-card-text>
   <v-expansion-panel>
     <v-expansion-panel-content v-for="(item,i) in items" :key="i">
       <div slot="header">{{item.title}}</div>
       <v-card-text v-if="i == 0 || i == 2 || i == 3" class="grey lighten-3">
       		{{item.content}}
       </v-card-text>
       <v-img v-if="i == 1" :src="join">
       </v-img>
       <v-btn v-if="i == 4" color="red darken-1" flat>
       	    update
       </v-btn>
     </v-expansion-panel-content>
   </v-expansion-panel>
 </v-card-text>
