Initial View
The Databuilder will initially only present the fields that are required. It can handle top level properties, arrays and nested objects.
Adding from available fields
The fields that you populate are from the target system. You can add fields that are optional by pressing the “cog” button in the top right corner of the databuilder, then selecting which fields you want to display:
Adding a Selector Template value
In the databuilder, values can be templated in a sentence format, so for example - you could combine{firstName} and
{lastName} to create a full name to a field called fullName.

Creating lists
You can create lists by using the “Add” button on the right hand side of the field. This will add an item to a list, which you can then populate with the fields you require.
Existing list items
You can also add existing list items from a previous node, to be spread into your databuilder list. This can be defined via a Selector.
