-# 2026-03-06 | ECX-8066 | 首页 body 高度计算方式调整
+# 2026-03-06 | ECX-8066 | 自定义导航左侧可配置显隐及分类页隐藏左侧
 
-- **说明**：首页 onReady 中 body 高度由直接使用 SpPage 传入的 height 改为使用 `calc(100vh - gNavbarH - footerHeight)` 计算，与导航栏、底栏高度对齐，避免高度偏差。
-- **涉及**：`src/pages/index.js`
-- **类型**：refactor
+- **说明**：SpPage 支持通过 `showNavitionLeft` 控制自定义导航左侧区域（返回/首页/功能区）是否展示；分类页、分类加购页传入 `showNavitionLeft={false}` 隐藏左侧，标题区无左侧时增加左内边距；导航区 padding 微调（左 30→20px，右 10→20px）。
+- **涉及**：`src/components/sp-page/header.js`、`src/components/sp-page/index.js`、`src/components/sp-page/index.scss`、`src/pages/category/index.js`、`src/pages/category/comps/comps-category-addCart.js`
