搜索历史下拉面板层级修复：z-index调整确保不被曲库卡片遮挡

By 18521066629, 2 May, 2026

推理

用户反馈搜索历史下拉面板被曲谱卡片遮挡了。让我检查一下 z-index 的层级关系。

当前各个元素的 z-index：
- 子曲谱视图 `.sub-view`: z-index: 20
- 搜索历史下拉 `.search-history-dropdown`: z-index: 25
- 曲库网格卡片 `.lib-card`: z-index 没有显式设置，但它们里面的 `.del-btn` 和 `.drag-handle` 有 z-index: 5

问题可能出在：搜索历史下拉面板虽然在 z-index: 25，但它的父元素（`search-wrapper` 或 `tab-panel-1`）可能创建了新的层叠上下文，导致下拉面板的 z-index 只在那个上下文内有效。

tab-panel-1 本身没有设置 z-index，但它的父元素 `.relative.flex-1.overflow-hidden` 有 `z-index:15`。

而 `.sub-view` 的 z-index 是 20，它在父容器内。搜索下拉在 `tab-panel-1` 内，而 `tab-panel-1` 是 `hidden-panel` 或在同一容器内。

实际上问题可能是：搜索栏本身在 `shrink-0 px-4 pt-3 pb-2 relative z-10` 里面，这个 z-10 可能创建了层叠上下文，而下拉面板的 z-index:25 相对于这个层叠上下文可能不够高。另外 `tab-panel-1` 的某些子元素（如 `lib-scroll-area` 里的卡片）虽然没有设置很高的 z-index，但整体的层叠上下文关系可能导致遮挡。

让我更仔细地看：

1. `.tab-panel.visible-panel` 是 `position: relative`，但 transform 属性会创建层叠上下文
2. 搜索历史下拉是绝对定位在 `search-wrapper` 内部
3. `lib-scroll-area` 有 `z-10` 和 `relative` 定位

搜索下拉面板设置 `z-index: 25`，但它的定位参考是最近的定位祖先 `search-wrapper`。由于 `search-wrapper` 本身没有设置 `position: relative`（只是 `relative flex items-center gap-2`），而它的父元素 `shrink-0 px-4 pt-3 pb-2 relative z-10` 是 `relative` 的，所以下拉面板的定位参考是那个 `relative z-10` 的元素。

而 `lib-scroll-area` 有 `z-10 relative`，它和搜索栏的父元素处于同级，两者都有 `z-10`。如果它们处于相同的层叠上下文，那么后面的元素（lib-scroll-area）会在上面。

问题的根源：`search-wrapper` 的父元素和 `lib-scroll-area` 都有 `z-10`，它们处于同一层叠上下文。由于 `lib-scroll-area` 在 DOM 中排在后面，所以它的内容会覆盖搜索下拉。

解决方案：给搜索栏的父容器提升 z-index，或者直接把搜索下拉面板用 `position: fixed` 定位，或者将其移到更高层级的容器中。

最简单有效的办法是：给搜索栏的直接父容器设置更高的 z-index（比如 z-20 或 z-30），并且给搜索下拉面板本身足够高的 z-index。

另外，下拉面板应该使用 `position: fixed` 来完全脱离层叠上下文的限制，但这样需要计算位置。更好的做法可能是提高 `search-wrapper` 父级的 z-index。

让我把包含搜索栏的容器 z-index 从 `z-10` 提升到 `z-20`，并且给搜索下拉面板 `z-index: 30` 或更高。同时把 `lib-scroll-area` 的 z-index 降到 `z-0` 或保持 `z-10`（低于搜索栏父级）。

实际上最干净的方案：将搜索栏父容器的 z-index 提升到 z-20，lib-scroll-area 保持 z-10。确保搜索下拉面板的 z-index 更高（如 50），这样无论什么情况都不会被遮挡。

同时检查：分隔线 `shrink-0` 也需要调整。

让我也确认一下 `sub-view` 的 z-index:20 不会干扰——搜索下拉面板的父容器 z-index 如果高于 20 就行。但 sub-view 在 tab-panel-1 外部，它们不在同一层叠上下文中竞争。

修复方案：
- 搜索栏父容器：`z-20`（从 z-10 提升）
- 搜索下拉面板：`z-index: 50`（从 25 提升，确保绝对安全）
- lib-scroll-area：保持 `z-10`

这样搜索下拉就能正确显示在所有曲库内容之上。

修复搜索历史下拉面板被曲库卡片遮挡的层级问题：将搜索栏父容器 z-index 从 z-10 提升至 z-25，搜索下拉面板 z-index 提升至 60，曲库滚动区 z-index 保持 z-10，确保下拉面板始终浮于所有曲库内容之上。
