API

MenuContext

It provides methods to handle popup menus imperatively. The same methods are exposed to the child context with name menuActions.

Note: It is important that <MenuContext /> is on the top of the component hierarchy (e.g. ScrollView should be inside of MenuContext) and wraps all <Menu /> components. This is needed in order to solve z-index issues. The only known exception is when you use Modal - you need to place (additional) 'MenuContext' inside of 'Modal' (see our ModalExample)

Methods, menuActions context

Method Name	Arguments	Notes
openMenu	name	Opens menu by name
toggleMenu	name	Toggle menu by name
closeMenu		Closes currently opened menu
isMenuOpen		Returns true if any menu is open

Properties

Option	Type	Opt/Required	Default	Note
style	Style	Optional		Style of wrapping View component. Same as customStyles.menuContextWrapper but when both are present result style is a merge where this style has higher precedence.
customStyles	Object	Optional		Object defining wrapper, touchable and text styles
backHandler	boolean|Function	Optional	false	Whether to close the menu when the back button is pressed or custom back button handler if a function is passed (RN >= 0.44 is required)

Custom styles

To style <MenuContext /> and backdrop component you can pass customStyles object prop with following keys:

Object key	Type	Notes
menuContextWrapper	Style	Style of wrapping View component
backdrop	Style	Backdrop View style

Note: Style type is any valid RN style parameter. Note: In addition to these styles we add also {flex:1}. You can disable it by e.g. style={{flex:0}}.

See more in custom styling example.

Handling of back button

To handle the back button you can pass backHandler prop with the following possible values:

Value	Description
false	No handling of back button press
true	The menu will be closed
Function	The function will be called with MenuContext instance as the first parameter. The function needs to return true to prevent application exit (or bubbling if there are other listeners registered). Read BackHandler documentation for more information.

renderers

Renderers are react components which wraps MenuOptions and are responsible for menu position and animation. The renderers module provides following renderers

• ContextMenu (default) - opens (animated) context menu over the trigger position. The ContextMenu.computePosition exports function for position calculation in case you would like to implement your own renderer (without special position calculation).
• NotAnimatedContextMenu - same as ContextMenu but without any animation.
• SlideInMenu - slides in the menu from the bottom of the screen.

It is possible to extend menu and use custom renderer (see implementation of existing renderers or extension guide).

Note: If you only need to add styles or wrap MenuOptions with your own component, use customStyles or renderOptionsContainer options of MenuOptions instead.
