Displays a set of items the user may choose from to take actions.


A Menu for Smart Devices is usually the entry point of a Smart Device application. It displays a set of items the user may choose from; for example, it may display items such as Work With pattern and Work With object, Panel object, Menus, links to web pages or actions like making a phone call or sending an email.

You can create a Menu for Smart Devices through the New Object dialog:

New Object - Menu for Smart Devices

Object properties

Remarkable properties of the Menu for Smart Devices object are listed below:

Once a Menu for Smart Devices has been created, it will have a tree-like interface where you can add the items to be displayed on it, and adjust their properties to your needs.

Menu node properties

By selecting the 'Menu' item on the tree, the following properties are available:

  • Title property
    Title for this Menu.
  • Background property
    Menu background image. It must be an Image object.
  • Header property
    Menu header image. It must be an Image object.
  • Class property
    Menu theme-class.
  • Control property
    Can be List, Tab, or Table.
  • Tabs Distribution property
    Only visible when the Control property value is Tabs. Indicates how the Tab options will be distributed in the Tab control for the Menu. Possible values are Platform Default, Fixed Size, and Scroll. The
    Fixed Size value applies when the control has few options (at most five); in that case, each of them has the same width in the Tab control. On the other hand, the Scroll value set each option to the required width depending on the image and caption. This option allows scrolling the tab control when the number of options exceeds the width of the screen.
    Applies only for Android; the Tab control in Menu for Smart Devices always behaves as Fixed Size value for iOS applications.
  • Appearance group

Items node properties

The Items are the elements that will make up the Menu (generally Work With for Smart Devices associated with the Transaction object or SD Panels). To add new Items, drag the object from the folder view to the Items node of the Menu. Also, you can right-click on the Items node and select Add Action.


Each Item has the following properties.

  • Name property
    Name of the option. This name will be referred to as its action on the Event tab.
  • Description property
    Description of the option. If its value is empty, the property name will be used. If you want an empty description on the Menu, add a blank space in the property.
  • Image property
    An icon used for the option. It must be an Image object. If Control property for Menu node is set to Tabs, iOS and Android require the image file format to be PNG and only its transparency will be taken into account.
  • Class property
    Menu Item theme-class used for the option.

  • (1) Deprecated as of Genexus 15 Upgrade 10 (no longer available).
  • As of GeneXus 16 upgrade 2, when using Tab control for Menu options, the ActivePageChanged event, and the Menu.ActivePage property is available to be used in the object events.
  • In iOS, showing a Menu as Tabs only works for the main object. If the Menu is not the application's main object and it has the Control property set to Tabs, it will be shown as a List. This is to conform to Apple's Human Interface Guidlines that state that:
    In general, use a tab bar to organize information at the app level. A tab bar is a good way to flatten your information hierarchy and provide access to several peer information categories or modes at once. ... A tab bar enables global navigation for your app, so it should remain visible everywhere.
