没必要嵌套这么多层，直接
{
options?: { appendTo?: string | HTMLElement }
}There was a problem hiding this comment.
这里不能直接改成顶层 options。该组件是 Tiptap 的 Vue NodeView，Tiptap 固定传入的 prop 是 extension，它代表当前的 Tiptap Node 扩展实例；扩展配置保存在 extension.options 中。
官方文档也明确说明 extension 用于访问扩展配置（“Access to the node extension, for example to get options”）。因此实际读取路径必须是：
props.extension.options.appendTo顶层 options 并不是 Tiptap NodeView 的运行时 prop。改成：
options?: {
appendTo?: string | HTMLElement
}虽然 TypeScript 可以通过，但运行时
props.options不会被注入，appendTo会丢失，自定义挂载目标无法生效并回退到body。已通过构建后的 E2E 验证：保留
extension.options时默认挂载和自定义HTMLElement挂载均正常；移除extension后自定义挂载失败。

问题描述：
appendTo 会直接传给 useTeleportTarget。当值是语法非法的 CSS 选择器时，例如：
TrSender.template(itemsContainingSelect, { appendTo: "[" })内部 querySelector 会抛出 SyntaxError，导致 Template Select 渲染中断，而不是按回退策略挂载到 body。
建议修改方案：
捕获选择器解析异常，并回退到 document.body；补充非法选择器回归用例，验证组件不会崩溃且下拉菜单挂载到 body。

问题描述：
当 Sender 挂载在 ShadowRoot 中时，useTeleportTarget 会把未配置 appendTo、appendTo 为 body 以及找不到的选择器都回退到 ShadowRoot。实际行为因此不再是 PR 声明的 body + fixed，也不再与修改前保持兼容；文档级下拉样式也可能无法跨越 Shadow DOM 边界。
建议修改方案：
为 Template Select 增加明确的 document.body 回退策略。由于其他组件可能依赖现有 ShadowRoot 语义，建议给共享 resolver 增加可配置 fallback，或在 Template Select 层包装处理。补充 ShadowRoot 下 undefined、body 和缺失选择器的回归用例。

背景
Template Select下拉菜单此前固定挂载到body，并使用fixed定位。在局部容器、嵌入式界面或独立 Surface 中使用时，弹层无法归属于对应容器的层叠上下文，可能出现层级或定位不符合预期的问题。
改动内容
为
TemplateOptions新增appendTo配置：支持通过 CSS 选择器或 DOM 元素指定
Template Select下拉菜单的 Teleport 目标。配置透传链路：
定位策略
根据实际挂载目标选择定位方式：
bodyfixedabsolute具体行为：
appendTo时，保持原有body + fixed行为。absolute定位。offset、flip、shift和autoUpdate定位逻辑。useTeleportTarget，统一处理选择器、DOM 元素和目标回退逻辑。容器解析与回退
appendTo为字符串时，通过 CSS 选择器查找目标元素。appendTo为HTMLElement时，直接使用该元素。body。appendTo时，默认挂载到body。使用方式
默认行为无需修改：
挂载到指定容器：
或传入 DOM 元素：
兼容性
appendTo时，行为与改动前保持一致。TemplateBlock、普通文本模板项和模板数据结构。测试验证
body。absolute定位。验证结果：
