public class ContextMenu extends ContextMenuBase<ContextMenu,MenuItem,SubMenu> implements HasMenuItems, HasOverlayClassName
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. You can use dividers to separate and group related content. Use dividers sparingly, though, to avoid creating unnecessary visual clutter.

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. Moreover, Context Menu supports checkable menu items that can be used to toggle a setting on and off. It also supports disabling menu items to show that they are unavailable. Menu items can also be customized to include more than a single line of text. You can use left-click to open Context Menu in situations where left-click does not have any other function, for example a Grid without selection support.

Best Practices:
Context Menu is used to provide shortcuts to the user. You should not use it as the only or primary means to complete a task. The primary way should be accessible elsewhere in the UI. Also note that 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.
