+# Advanced Mega Menu layout
+
+**Metronic 9 reference:** [Demo 7](https://keenthemes.com/metronic/tailwind/react/demo7)
+
+A header-only layout: the whole application menu lives in a mega menu beside the logo, and the page
+content runs full width beneath it. The header becomes sticky and shrinks past
+`layouts.advanced-mega-menu-layout.headerStickyOffset`.
+
+## Composition
+
+| Piece                   | Source                                        |
+| ----------------------- | --------------------------------------------- |
+| Mega menu               | `MegaNavMenu` from `../shared`                |
+| Mobile menu (sheet)     | `SidebarAccordionMenu` from `../shared`       |
+| Toolbar and breadcrumbs | `Toolbar` / `ToolbarHeading` from `../shared` |
+| Footer                  | `AppFooter` from `../shared`                  |
+| Account menu            | `UserAvatarMenu` from `../shared`             |
+
+Layout-specific: `Header`, `HeaderLogo`.
+
+## Notes
+
+- The mega menu panels show two levels — a section's children as columns, their children as links.
+  Deeper entries stay reachable through the toolbar breadcrumbs and the mobile accordion.
+- The `data-sticky-header` body attribute is removed on unmount.
