    <n-timeline-item
      v-for="log in activityLogs"
      :key="log.id"
      :type="log.type"
      :title="log.title"
      :content="log.description"
      :time="log.timestamp"
    >
      <template #icon>
        <n-icon>
          <component :is="getIcon(log.type)" />
        </n-icon>
      </template>
    </n-timeline-item>
  </n-timeline>
</template>

<script setup>
import { CheckCircleIcon, AlertIcon, InfoIcon } from '@vicons/ionicons5'

const activityLogs = [
  { id: 1, type: 'success', title: 'Task Completed', description: 'All items processed', timestamp: '10:00' },
  { id: 2, type: 'warning', title: 'Warning', description: 'Low disk space', timestamp: '11:00' },
  { id: 3, type: 'error', title: 'Error', description: 'Connection failed', timestamp: '12:00' }
]

const getIcon = (type) => {
  const icons = {
    success: CheckCircleIcon,
    warning: AlertIcon,
    error: AlertIcon,
    info: InfoIcon
  }
  return icons[type] || InfoIcon
}
</script>
```

### Horizontal Progress

```vue
<template>
  <n-timeline horizontal>
    <n-timeline-item
      v-for="(step, index) in steps"
      :key="index"
      :type="step.completed ? 'success' : 'default'"
      :title="step.title"
    >
      <template #icon>
        <n-icon v-if="step.completed">
          <CheckIcon />
        </n-icon>
        <span v-else>{{ index + 1 }}</span>
      </template>
    </n-timeline-item>
  </n-timeline>
</template>

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

const steps = ref([
  { title: 'Cart', completed: true },
  { title: 'Shipping', completed: true },
  { title: 'Payment', completed: false },
  { title: 'Confirm', completed: false }
])
</script>
```

### Dashed Line Style

```vue
<template>
  <n-timeline>
    <n-timeline-item
      type="info"
      title="Upcoming Event"
      content="This event is in the future"
      line-type="dashed"
    />
    <n-timeline-item
      type="success"
      title="Completed"
      content="This event is done"
    />
  </n-timeline>
</template>
```

### Rich Content

```vue
<template>
  <n-timeline>
    <n-timeline-item>
      <template #header>
        <n-space align="center">
          <n-avatar :size="24">JD</n-avatar>
          <span>John Doe</span>
        </n-space>
      </template>
      
      <template #default>
        <n-card size="small">
          <p>Posted a new article about Vue.js best practices</p>
        </n-card>
      </template>
      
      <template #footer>
        <n-space>
          <n-button text size="small">Like</n-button>
          <n-button text size="small">Comment</n-button>
        </n-space>
      </template>
    </n-timeline-item>
  </n-timeline>
</template>
```

## Best Practices

### 1. Use Appropriate Types

Match the timeline item type with the event status:

```vue
<n-timeline-item type="success" content="Completed" />
<n-timeline-item type="error" content="Failed" />
<n-timeline-item type="warning" content="Attention needed" />
<n-timeline-item type="info" content="Information" />
```

### 2. Use Horizontal for Process Steps

```vue
<n-timeline horizontal>
  <!-- Step items -->
</n-timeline>
```

### 3. Add Context with Time

```vue
<n-timeline-item
  title="Event"
  content="Description"
  time="2024-01-15 10:00"
/>
```

### 4. Use Custom Icons for Visual Clarity

```vue
<template #icon>
  <n-icon :color="statusColor">
    <StatusIcon />
  </n-icon>
</template>
```

### 5. Combine with Cards for Rich Content

```vue
<n-timeline-item>
  <n-card>
    <!-- Rich content -->
  </n-card>
</n-timeline-item>
```
