TMenubar class

A desktop-application-style horizontal menu bar with nested dropdown menus (File, Edit, View, …), for admin tools that need classic app chrome above or inside TLayout.

Built directly on TMenuRootTrigger — the same hover/tap-to-open-panel engine behind TDropdown and the sidebar's submenus — so each top-level label is just a dropdown trigger positioned in a row; no separate overlay/positioning logic lives in this widget.

TMenubar(
  menus: [
    TMenubarMenu(label: 'File', items: [
      TDropdownItem(text: 'New', icon: Icons.note_add, onTap: _onNew),
      const TDropdownItem(customContent: Divider(height: 1)),
      TDropdownItem(text: 'Exit', onTap: _onExit),
    ]),
  ],
)
