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

import { Search as SearchIcon } from '@vicons/ionicons5'

const searchQuery = ref('')
const items = ref([])
const filteredResults = computed(() => {
  if (!searchQuery.value) return items.value
  return items.value.filter(item =>
    item.name.toLowerCase().includes(searchQuery.value.toLowerCase())
  )
})

const clearSearch = () => {
  searchQuery.value = ''
}
</script>

    h(NEmpty, {
      description: 'No data available',
      size: 'small'
    }, {
      extra: () => h(NButton, {
        size: 'small',
        onClick: () => console.log('Refresh')
      }, () => 'Refresh')
    })
  ])
}
</script>

      <n-space>
        <n-switch v-model:value="showIcon">Icon</n-switch>
        <n-switch v-model:value="showDescription">Description</n-switch>
      </n-space>
    </template>
  </n-empty>
</template>

<script setup>
import { ref } from 'vue'

const showIcon = ref(true)
const showDescription = ref(true)
</script>

Best Practices

1. Provide actionable feedback: Add action buttons in the extra slot

   <n-empty description="No items">
     <template #extra>
       <n-button @click="handleAdd">Add Item</n-button>
     </template>
   </n-empty>
   

2. Use appropriate size: Match the empty state size to the context

   <n-empty size="small" description="No data" />
   

3. Contextual icons: Use icons that match the empty state context

   <n-empty description="No search results">
     <template #icon>
       <n-icon><SearchIcon /></n-icon>
     </template>
   </n-empty>
   

4. Clear description: Write clear, helpful descriptions

   <n-empty description="No messages in your inbox" />
   

5. Hide elements when needed: Use show-icon and show-description for flexibility

   <n-empty :show-icon="false" description="Simple text only" />
   

6. Use in containers: Place empty states in cards or containers for better layout

   <n-card>
     <n-empty description="No content" />
   </n-card>
