ContextMenu plugin — and the shared Menu class
ContextMenu ('contextMenu') provides the right-click menu over cells and headers. It owns the shared Menu class that DropdownMenu reuses. Read this before touching contextMenu.ts, the menu/ UI, or anything that dropdownMenu builds on.
Context Menu vs Column Menu
DropdownMenu is built on the shared Menu class from contextMenu but is configured and triggered independently. When in doubt about which plugin owns a behavior, use this table.
| Context menu | Column menu (dropdown menu) | |
|---|---|---|
| Plugin class / key | ContextMenu / 'contextMenu' | DropdownMenu / 'dropdownMenu' |
| Trigger | Right-click (or Ctrl+Shift+\ / Shift+F10) | Column header button (or Shift+Alt+ArrowDown) |
| Scope | Cells and headers across rows and columns | Column-specific operations only |
| Hook prefix | beforeContextMenu*, afterContextMenu* | beforeDropdownMenu*, afterDropdownMenu* |
