title: 头部插槽
---

通过 `#header` 插槽用于自定义输入框的头部内容。

::: warning 废弃警告
以下方法将在下个大版本中移除，推荐使用 `v-model:openHeader` 进行双向绑定控制：

- `senderRef.value.openHeader()` 打开头部容器 (已废弃)
- `senderRef.value.closeHeader()` 关闭头部容器 (已废弃)
:::

::: tip 推荐用法
使用 `v-model:openHeader` 进行双向绑定控制头部显示状态：

```vue
<Sender v-model:openHeader="openHeader">
  <template #header>头部内容</template>
</Sender>
```
:::
</docs>

<script setup lang="ts">
import { CircleClose } from '@element-plus/icons-vue';

const senderValue = ref('');
const openHeader = ref(true); // 使用 v-model:openHeader 控制头部显示状态

function toggleHeader() {
  openHeader.value = !openHeader.value;
}

function closeHeader() {
  openHeader.value = false;
}
</script>

<template>
  <div
    style="
      display: flex;
      flex-direction: column;
      gap: 12px;
      height: 300px;
      justify-content: space-between;
    "
  >
    <el-button style="width: fit-content" @click="toggleHeader">
      {{ openHeader ? '关闭头部' : '打开头部' }}
    </el-button>
    <Sender v-model="senderValue" v-model:open-header="openHeader">
