Troubleshooting a Recursive Menu Problem in Vue.js

I've been attempting to create a recursive menu in Vue.js, but I keep encountering an error and I'm struggling to identify the issue. Here is my current structure:

MenuList.vue

<template>
    <ul class="menu">
        <MenuLink v-for="menuItem in menuObject" :menuItem="menuItem" :key="menuItem.i"></MenuLink>
    </ul>
</template>

<script>
import MenuLink from './MenuLink'

export default {
  name: 'MenuList',
  components: {MenuLink},
  props: ['menuObject'],
  data () {
    return {
    }
  }
}
</script>

And MenuLink.vue

<template>
    <li>
        <a href="#">
            {{ menuItem.resourceKey }}
        </a>

        <MenuList :menuObject="menuItem.subMenuItems" v-if="menuItem.subMenuItems"></MenuList>
    </li>
</template>

<script>
  import MenuList from '@/components/common/menu/MenuList'

  export default {
    name: 'MenuLink',
    components: {MenuList},
    props: ['menuItem'],
    data () {
      return {
      }
    }
  }
</script>

However, when the MenuList component is included inside MenuLink, the following error is displayed:

[Vue warn]: Unknown custom element: <MenuList> - did you register the component correctly?
For recursive components, make sure to provide the "name" option.
found in
---> <MenuLink> at src\components\common\menu\MenuLink.vue
       <MenuList> at src\components\common\menu\MenuList.vue

I am stuck on what might be causing this problem. Does anyone have any insights?

Answer №1

All you need to do is declare it globally in your app.js. For example:

import DropdownMenu from '@/components/shared/menu/DropdownMenu'
Vue.component('DropdownMenu', DropdownMenu);
