 # Changelog
 
+## 2026-01-27 - 3.8.0 - feat(sidebar)
+rename demoGroup to demoGroups, add multi-group support, search by group name, and context menu group navigation
+
+- Static property demoGroup renamed to demoGroups; accepts string | string[] for multi-group membership
+- Elements with multiple demoGroups appear in each group's sidebar section simultaneously and show the library_books icon instead of featured_video
+- Sidebar search now matches group names in addition to element names; groups are sorted alphabetically by group name
+- Context menu for elements includes a "Show in Group:" section with navigable group entries that scroll to and briefly highlight the target group; group headers also have a context menu entry to filter by that group
+- Added data-group attribute on .item-group for DOM querying and visual classes for group highlight and filter match
+- Updated test elements to use demoGroups and updated docs/changelog/readme.hints to document the new behavior
+- Bumped several devDependencies (@api.global/typedserver, @git.zone/tsbuild, @git.zone/tsbundle, @git.zone/tstest, @git.zone/tswatch, @types/node) and adjusted npm script `watch` to use tswatch
+
+## 2026-01-27 - 3.8.0 - feat(sidebar)
+rename demoGroup to demoGroups, add multi-group support, search by group name, and context menu group navigation
+
+- Rename static property `demoGroup` to `demoGroups` on element classes; accepts `string | string[]` for multi-group membership
+- Elements with an array of `demoGroups` appear in each group's sidebar section simultaneously
+- Search now matches group names in addition to element names (e.g. searching "Buttons" shows all elements in the Buttons group)
+- Groups are sorted alphabetically by group name instead of by first element name
+- Elements belonging to multiple groups display a `library_books` icon instead of `featured_video`
+- Right-click context menu on elements with groups shows "Show in Group:" section with navigable group entries
+- Clicking a group name in the context menu scrolls to and briefly highlights that group in the sidebar
+- Updated test elements (test-button-primary, test-button-secondary, test-button-danger, test-input-text, test-input-checkbox) to use `demoGroups`
+
+## 2026-01-04 - 3.7.1 - fix(sidebar)
+increase scrolled sidebar header box-shadow intensity and size to improve visual separation
+
+- Changed .sidebar-header.scrolled box-shadow from `0 4px 12px -2px rgba(0, 0, 0, 0.4)` to `0 8px 24px -2px rgba(0, 0, 0, 1)`
+- File modified: ts_web/elements/wcc-sidebar.ts — stronger, larger, and fully opaque shadow for better contrast when scrolled
+
+## 2026-01-04 - 3.7.0 - feat(wcc-sidebar)
+add header shadow and scrolled state for sidebar menu to show elevation when content is scrolled
+
+- Introduce isMenuScrolled state to track whether the menu has been scrolled
+- Add handleMenuScroll handler and bind it to the menu scroll event
+- Apply a 'scrolled' class to .sidebar-header to add box-shadow and border-bottom color with transitions
+- Update template to conditionally add scrolled class and attach scroll listener
+
+## 2026-01-04 - 3.6.2 - fix(wcc-sidebar)
+use sidebar's internal .menu element for scroll management and expose scrollableContainer getter
+
+- Add public scrollableContainer getter to wcc-sidebar that returns the .menu element for external scroll control
+- Update wcc-dashboard to query wcc-sidebar as WccSidebar and attach scroll listeners to sidebar.scrollableContainer instead of the host element
+- Restore sidebar scroll position by setting scrollTop on the scrollableContainer when applying saved positions
+- TypeScript casting added to avoid nullable/implicit any issues when querying the sidebar element
+
 ## 2026-01-04 - 3.6.1 - fix(wcc-sidebar)
 sort sidebar items alphabetically and unify grouped and ungrouped items for consistent ordering

+## Element Demo Groups (2026-01-27)
+
+### Overview
+Elements can declare `demoGroups` (renamed from `demoGroup`) as a static property to appear grouped in the sidebar. Supports `string | string[]` — elements with an array appear in multiple groups simultaneously.
+
+### Usage
+```typescript
+// Single group
+public static demoGroups = 'Buttons';
+
+// Multiple groups — element appears in both
+public static demoGroups = ['Buttons', 'Form Controls'];
+```
+
+### Features
+- Search matches group names (searching "Buttons" shows all elements in that group)
+- Groups sorted alphabetically by group name
+- Multi-group elements show `library_books` icon instead of `featured_video`
+- Context menu shows "Show in Group:" with clickable group entries that scroll to and highlight the group
+- `data-group` attribute on `.item-group` containers for DOM querying
+
+### Files Changed
+- `ts_web/elements/wcc-sidebar.ts` — grouping logic, search filter, sort key, icon, context menu, scrollToGroup
+- `test/elements/test-button-*.ts`, `test/elements/test-input-*.ts` — renamed `demoGroup` → `demoGroups`
