Date: 2026-08-29 12:07 Summary: Restored homepage topic dropdowns; fixed tool-page Tools mega menu hover by dropping Bootstrap dropdown in favor of CSS :hover.
[question] 首页不要改，只改动slug工具页，分主题的菜单收起在工具菜单中，鼠标悬停展开这个没有实现。
[try to solve]
Homepage buildHomeNavItems again uses 16 topic dropdowns + topics / where2use / tool-type / devlogs (multirow CSS under body.is-home-page only). Tool slug pages keep Home → Tools mega → Tool topics → Tool types → Dev logs.
Hover failed because Bootstrap data-bs-toggle="dropdown" owned display. Replaced mega markup with .tools-mega-panel (no Bootstrap dropdown); desktop show via :hover / :focus-within with display: grid !important; mobile click toggles .is-open. Rebuilt site; verified home has no mega panel and 16 dropdowns; tool page has mega panel without data-bs-toggle.
