Menu Bar Widget (Themable)
 |
This widget is a web component that is available as a preview. It includes a subset of features from the current Menu widget. Additional features and migration support will be added in future releases.
|
Use the Menu Bar widget to create a navigation layout for solutions that contains multiple mashups or pages. The widget displays navigation links as a list of items that a user can choose from. You can configure each item on the widget to navigate users to a mashup, web page, or submenu. The widget is permanently displayed on the left side of the top-level container in a layout. You can use the widget to create menus with single level or multiple levels of navigation. You can define menu items by creating menu entities in Composer, or by writing data services that generate data-driven menus. This lets you build more complex mashups with different views across multiple pages.
Watch the following video on how to define the menu items and use the widget to replace a contained mashup. To open the video in a new tab, click the title on the player.
In addition to the Mashup Builder widget, the Menu Bar includes the following components:
• The MenuEntry Data Shape. This is used to define the infotable for the menu bar configuration in a data service.
• A Mashup and a Master layout template that includes pre-configured layout containers and a Menu Bar widget. Use this template to create a simple layout quickly.
Choosing a Menu Design: Accordion and Cascading Menus
You can configure the widget to control how multiple levels of navigation are displayed on the menu bar using the SubMenuType property. Submenus are displayed in one of two ways:
• Cascading menus(default)—Open to the right where each navigation level is displayed as a separate submenu.
• Nested accordion sections—Open vertically where each navigation level is indented to the right.
The following image shows the default cascading menu on the left and the nested accordion menu on the right.
The compact view is disabled in these two Menu Bar widgets, and the same menu entities are selected for the primary and secondary navigation data properties. The cascading menu is divided into three sections. The top section is used to display the primary navigation items. The two sections at the bottom display the secondary navigation items and the footer. In the accordion menu, secondary navigation items that are displayed above the footer are combined with the primary items into one section.

2. Primary navigation items
3. Drag handle used to increase or decrease the menu bar width (optional).
