Context Menu
API: TypeScript / Java
Source: TypeScript / Java
Context Menu is a component that you can attach to any component to display a context menu. The menu appears on right (default) or left click. On a touch device, a long press opens the context menu.

Important
| Open the Context Menu by right-clicking (mouse) or long-pressing (touch) a Grid row. |

</vaadin-grid>
</vaadin-context-menu>Dividers
You can use dividers to separate and group related content. Use dividers sparingly to avoid creating unnecessary visual clutter.

}
itemSelected(e: ContextMenuItemSelectedEvent) {
this.items.forEach((item) => {
item.checked = item === e.detail.value;
});
this.items = [...this.items];
}Hierarchical Menu
Context Menu, like Menu Bar, supports multi-level sub-menus. You can use a hierarchical menu to organize a large set of options and group related items.

</vaadin-context-menu>Left-Click
You can use left-click to open Context Menu in situations where left-click doesn’t have any other function, for example a Grid without selection support.

</vaadin-context-menu>Best Practices
Context Menu is used to provide shortcuts to the user. You shouldn’t use it as the only or primary means to complete a task. The primary way should be accessible elsewhere in the UI.

Important
| Open the Context Menu by right-clicking (desktop) or long-pressing (mobile) a Grid row, or use the Menu Bar in the last column. |

</vaadin-context-menu>Context Menu vs Menu Bar
You should use Context Menu when there is no dedicated button for opening an overlay menu, such as right-clicking a grid row. When there is a dedicated element/component, such as an overflow menu, use Menu Bar.
