When you click a hierarchy field, the details of the hierarchy
field appears in the hierarchical type panel.
In the hierarchical type panel, you can see the schema and values for
the hierarchical data selected. You can navigate through the structure with the
breadcrumbs. If the structure is very deep, you can expand and collapse the
fields. When you expand the structure, you can view the data within the
hierarchy. For example, when you view billing information in the hierarchical
type panel, you can see the values for the billing name, street and ZIP Code.
When you expand all
rows, the Developer tool expands a maximum of 500 rows. If you have more than
500 rows, you can manually expand them to view more information.
