Hierarchy View

Fiori: HierarchyView

Intro

The hierarchy view is a set of columns that show the hierarchical relationships between objects. Typically, the hierarchy view shows a parent/child and sibling relationship but may also show more complex relationships that are several levels deep, such as a great-grandparent/great-grandchild.

Example of hierarchy view on mobile (left) and tablet (right)

Usage

Use the hierarchy view if the user needs to see the relationship of an object, such as its parent, children, and sibling objects.

Don't

Do not use the hierarchy view for a single level of data. Instead, use a list of standard object cells.
Limit the content used in the hierarchy object cell. Due to the hierarchy accessory, space is limited.

Anatomy

The hierarchy view is organized into columns depending on how many levels are expanded and the kind of device that the user is using.

Mobile

A. Navigation Bar

The navigation bar is used only for the hierarchy view on small screens. It is used to navigate up and down the hierarchy levels. It would be used for the hierarchy view on mobile and hierarchy view in a dialog.

B. Object Cell

The hierarchy view cell is based on the object cell. The only difference is the additional hierarchy accessory. For more information, see object cells.

C. Hierarchy Icon

The hierarchy icon allows users to view an object’s children. When selected, the icon toggles from a default state to a selected state. If there are no further children, the hierarchy accessory is empty.

D. Direct Objects Count

The direct objects count shows the total number of direct child objects. Displaying the direct objects count is optional.

E. Object Cell

The hierarchy view cell is based on the object cell. The only difference is the additional hierarchy accessory. For more information, see object cells.

F. Overflow Preview

The overflow preview displays a hint of the parent and/or child level that is outside of the viewport. This is only available on large screen sizes.

H. Direct Objects Count

The direct objects count shows the total number of direct child objects. Displaying the direct objects count is optional.

I. Navigation Bar

The navigation bar is used only for the hierarchy view on small screens. It is used to navigate up and down the hierarchy levels. Users can see the hierarchy view on mobile and hierarchy view in a dialog.

J. List Picker Form Cell

The list picker allows users to select options that have different hierarchy levels. Provide the hierarchy view cell with either radio buttons for single select or checkboxes for multi-select. For more information, see list picker form cells.

Behavior and Interaction

Hierarchy Accessory

Tapping on the hierarchy accessory leads the hierarchy view to access the selected object’s children. On tablet, it expands into another column. On mobile, the screen transitions to another view. If the user has navigated into more levels than the device can display, the view shifts to display the newest views and the highest ancestor level is out of view.
