Structured Data

KraftAdmin supports editing complex structured values beyond primitive fields.

Supported field types include:

• JSON
• ARRAY
• OBJECT

JSON

JSON fields are useful for storing flexible configuration or metadata.

@KraftAdminField(
    inputType = FormInputType.JSON
)
var settings: String = "{}"

The editor provides syntax highlighting and formatted JSON editing.

Arrays

Arrays allow editing ordered collections.

@KraftAdminField(
    inputType = FormInputType.ARRAY
)
var tags: List<String> = emptyList()

Administrators can add, remove and reorder values.

Objects

Object fields represent nested structures.

@KraftAdminField(
    inputType = FormInputType.OBJECT
)
var address: Address = Address()

Nested properties are rendered using expandable forms.

Validation

Structured fields continue to support normal validation.

@KraftAdminField(
    required = true
)

Typical Use Cases

JSON

• Application settings
• Dynamic schemas
• API payloads

Arrays

• Tags
• Categories
• Skills
• Labels

Objects

• Addresses
• Contact information
• Embedded value objects
• Nested configuration

Best Practices

Use strongly typed entities whenever possible.

Reserve JSON fields for data whose structure changes frequently.
