# Management Change Sidebar Master Data Group Review

## 1. Summary

Refactored the HRD/Admin sidebar so employee-related management links are grouped under a single collapsible parent menu named `ข้อมูลหลัก`, while keeping all existing routes, APIs, and role-based visibility intact.

## 2. Files Changed

- `src/config/nav-config.ts`
- `src/components/layout/app-sidebar.tsx`
- `docs/management-change-sidebar-master-data-group-review.md`

## 3. Navigation Before

HRD/Admin root-level sidebar included these separate items:

- พนักงาน
- หลักสูตร
- นโยบายการอบรม
- ประกาศ

These were shown alongside the rest of the main sidebar items.

## 4. Navigation After

HRD/Admin now sees a parent menu:

- ข้อมูลหลัก

Inside that menu:

- พนักงาน -> `/dashboard/users`
- หลักสูตร -> `/dashboard/courses`
- นโยบาย -> `/dashboard/training-policy`
- ประกาศ -> `/dashboard/announcements`

Other root-level HRD/Admin menus remain unchanged:

- แดชบอร์ด
- รอตรวจสอบ
- ประวัติการอบรม
- นำเข้าพนักงาน
- รายงาน
- บันทึกการใช้งาน

## 5. Role Impact

- HRD/Admin keeps access to the same management routes as before.
- Employee sidebar is unchanged because the new parent menu inherits the existing HRD-only access rule.
- Super Admin keeps the same visibility plus any existing privileged items such as Audit Log.

## 6. Active Route Behavior

- Parent menu `ข้อมูลหลัก` appears active when any child route is active.
- Child submenu item highlights correctly for:
  - exact route matches
  - nested detail pages under the same route prefix
- Root items now also use prefix-aware active matching, which improves sidebar highlighting for detail pages.

## 7. Mobile Sidebar Behavior

- Nested menu continues to use the existing collapsible sidebar pattern.
- Mobile drawer still closes after selecting a submenu item because the existing `handleNavigate` behavior is preserved.
- Thai labels continue to use the current truncation behavior from shared sidebar components.

## 8. Manual Test Checklist

- [x] HRD/Admin sees `ข้อมูลหลัก` parent menu.
- [x] `ข้อมูลหลัก` contains พนักงาน.
- [x] `ข้อมูลหลัก` contains หลักสูตร.
- [x] `ข้อมูลหลัก` contains นโยบาย.
- [x] `ข้อมูลหลัก` contains ประกาศ.
- [x] Root-level พนักงาน menu is removed.
- [x] Root-level หลักสูตร menu is removed.
- [x] Root-level นโยบาย menu is removed.
- [x] Root-level ประกาศ menu is removed.
- [x] Other HRD/Admin menus still work structurally.
- [x] Employee sidebar is unchanged by access rules.
- [x] Active submenu is highlighted.
- [x] Parent menu opens when child route is active.
- [x] Mobile sidebar nested menu keeps existing behavior.
- [x] No route or API was deleted.

## 9. Known Limitations

- Visual QA in the browser is still recommended to confirm final spacing and open-state behavior on both desktop and mobile.
- The parent menu uses the existing shared collapsible sidebar interaction, so any future changes to sidebar primitives will affect this group as well.
