Context Menu `<mv-context-menu>`

Menu contextuel ouvert au niveau du pointeur (clic droit), par appui long sur écran tactile ou au clavier (Maj+F10 / touche Menu) ; réutilise le moteur et les styles de Menu, y compris l’animation data-motion="glide".

Catégorie	Superpositions
Type	Web Component (`<mv-context-menu>`)
Statut	stable
Installe aussi	menu, popover
Keywords	context-menu, right-click, long-press, menu, submenu

When to use

Items in a file list, canvas or table need actions on right-click or touch long-press
Power users expect contextual actions at the pointer, with keyboard access through Shift+F10 or the Menu key

Avoid when

The actions are hidden only behind right-click with no visible trigger to discover them → use Menu instead
The area is plain reading content where users expect the browser menu for copy and search
