Example 1

A simple object field. If you give Alpaca an object as it's data, it automatically figures out what to do and sets up both sub-fields for you.

Example 2

Here we provide a schema to go along with our data. The schema simply provides a bit more information about the two sub-fields, such as their type and labels.

Example 3

Here is a more complex example that provides the data, schema and options for all of the sub-fields of the object.

Example 4

Object field with schema, options and view parameter.

Example 5

Object field with default value.

Example 6

Object field with lazy loading option. The lazy loading option is useful for improving performance of rendering forms for large schemas.

Example 7

Object field rendered in display-only mode. The gender field is hidden.

Example 8

Object with a required field specified at the field level.

Example 9

Object with a required field specified at the object-level.

Example 10

Object that utilizes field-level order property to apply an order to child fields.

Example 11

Here is an example of an object field where we use a top-level layout and a nested override of the view to force the email address into display mode only.
