Working with Options - Kodexa Developer Portal

Options are a powerful feature in Kodexa that allow you to define configuration parameters for components, capture user input, and enable flexible customization of behavior. They provide a declarative way to create configuration interfaces without writing UI code.

Quick Start

Options appear throughout Kodexa in metadata definitions for assistants, models, taxonomies (data definitions), actions, and pipeline steps. Here’s a simple example:

options:
  - name: hostname
    type: string
    label: Server Hostname
    description: The hostname or IP address of the server
    required: true
  - name: port
    type: number
    label: Port Number
    description: The port number for the connection
    default: 22

This creates two configuration fields that users can fill in, and the values are passed to your code at runtime.

How Users Experience Options

Options create interactive configuration interfaces in several areas:

Assistant Configuration

When users add an assistant to their project, they can configure it through options you define:

Document Labeling Properties

When labeling documents, users can set properties on labels based on options defined in your taxonomy:

Options keep users focused on content while configuring the system to their needs.

Working with Lists and Objects

Two of the most powerful option types are list and object, which allow you to define complex, structured data. Understanding how to use these properly is critical for building flexible configurations.

List Options

Lists allow you to define arrays of values, either simple strings or complex objects. Use type: list with the listType parameter to specify what kind of items the list contains.

String Lists

For lists of simple string values, use type: list with listType: string:

options:
  - name: allowed_prefixes
    type: list
    listType: string
    label: Allowed Prefixes
    description: List of allowed prefix strings
    default:
      - income_statement___
      - balance_sheet___
      - cash_flow___

Key points:

type: list indicates this is an array
listType: string specifies array items are strings
default should be an array of strings
Users can add/remove items through the UI

Resulting value in code:

allowed_prefixes = options.get('allowed_prefixes', [])
# ['income_statement___', 'balance_sheet___', 'cash_flow___']

Object Lists

For lists of complex objects, use type: list with listType: object and define the object structure using groupOptions:

options:
  - name: sections
    type: list
    listType: object
    label: Document Sections
    description: Configure sections to extract from documents
    default:
      - heading: Executive Summary
        required: true
        page_limit: 2
      - heading: Financial Data
        required: true
        page_limit: 5
    groupOptions:
      - name: heading
        type: string
        label: Section Heading
        description: The heading text to look for
        required: true

      - name: required
        type: boolean
        label: Required Section
        description: Whether this section must be present
        default: false

      - name: page_limit
        type: number
        label: Maximum Pages
        description: Maximum number of pages for this section
        min: 1
        max: 50
        default: 10

Key points:

type: list indicates this is an array
listType: object specifies array items are objects
groupOptions defines the schema for each object in the array
default should be an array of objects matching the schema
Each object in the default must conform to the groupOptions structure

Resulting value in code:

sections = options.get('sections', [])
# [
#   {'heading': 'Executive Summary', 'required': True, 'page_limit': 2},
#   {'heading': 'Financial Data', 'required': True, 'page_limit': 5}
# ]

for section in sections:
    heading = section.get('heading')
    is_required = section.get('required', False)
    page_limit = section.get('page_limit', 10)

Nested Lists in Objects

You can nest lists within objects for complex hierarchical structures:

options:
  - name: field_mappings
    type: list
    listType: object
    label: Field Mappings
    description: Define how to map source fields to target fields
    groupOptions:
      - name: source_field
        type: string
        label: Source Field Name
        required: true

      - name: target_field
        type: string
        label: Target Field Name
        required: true

      - name: transformations
        type: list
        listType: string
        label: Transformations
        description: List of transformations to apply
        default:
          - trim
          - lowercase

Resulting structure:

field_mappings = options.get('field_mappings', [])
# [
#   {
#     'source_field': 'CustomerName',
#     'target_field': 'customer_name',
#     'transformations': ['trim', 'lowercase', 'remove_special_chars']
#   }
# ]

Object Options

Objects allow you to group related options together. Use type: object with groupOptions to define the object’s properties.

Simple Object

options:
  - name: database_config
    type: object
    label: Database Configuration
    description: Database connection settings
    properties:
      collapsible: true
    groupOptions:
      - name: host
        type: string
        label: Database Host
        default: localhost
        required: true

      - name: port
        type: number
        label: Database Port
        default: 5432
        min: 1
        max: 65535

      - name: database_name
        type: string
        label: Database Name
        required: true

      - name: use_ssl
        type: boolean
        label: Use SSL Connection
        default: true

Key points:

type: object indicates this is a structured object
groupOptions defines the properties of the object
properties.collapsible: true makes the group collapsible in the UI
Each property in groupOptions follows the same option structure

Resulting value in code:

db_config = options.get('database_config', {})
host = db_config.get('host', 'localhost')
port = db_config.get('port', 5432)
database_name = db_config.get('database_name')
use_ssl = db_config.get('use_ssl', True)

Nested Objects

Objects can contain other objects for deep hierarchical structures:

options:
  - name: api_config
    type: object
    label: API Configuration
    groupOptions:
      - name: authentication
        type: object
        label: Authentication Settings
        groupOptions:
          - name: method
            type: select
            label: Auth Method
            possibleValues:
              - label: API Key
                value: api_key
              - label: OAuth 2.0
                value: oauth2

          - name: api_key
            type: string
            label: API Key
            password: true
            showIf: "this.api_config.authentication.method === 'api_key'"

          - name: oauth_settings
            type: object
            label: OAuth Settings
            showIf: "this.api_config.authentication.method === 'oauth2'"
            groupOptions:
              - name: client_id
                type: string
                label: Client ID
              - name: client_secret
                type: string
                label: Client Secret
                password: true

Best Practice: Limit nesting to 2-3 levels maximum for better user experience.

Default Value Structures

Default values must match the type structure:

Type	Default Value Structure	Example
`string`	Single string value	`default: "localhost"`
`text`	Single string (can be multiline)	`default: "Line 1\nLine 2"`
`number`	Single numeric value	`default: 5432`
`boolean`	Single boolean value	`default: true`
`select`	Single value from possibleValues	`default: "json"`
`list` (string)	Array of strings	`default: ["item1", "item2"]`
`list` (object)	Array of objects	`default: [{name: "val"}]`
`object`	Object with properties	`default: {host: "localhost"}`

Examples of Correct Default Values

# String - single value
- name: hostname
  type: string
  default: "localhost"

# Number - single value
- name: port
  type: number
  default: 5432

# Boolean - single value
- name: enabled
  type: boolean
  default: true

# Select - single value (must match a possibleValue)
- name: format
  type: select
  default: "json"
  possibleValues:
    - label: JSON
      value: json
    - label: CSV
      value: csv

# List of strings - array of strings
- name: tags
  type: list
  listType: string
  default:
    - production
    - verified
    - active

# List of objects - array of objects
- name: endpoints
  type: list
  listType: object
  default:
    - url: "https://api1.example.com"
      timeout: 30
    - url: "https://api2.example.com"
      timeout: 60
  groupOptions:
    - name: url
      type: string
    - name: timeout
      type: number

# Object - object with properties
- name: connection
  type: object
  default:
    host: "localhost"
    port: 5432
    ssl: true
  groupOptions:
    - name: host
      type: string
    - name: port
      type: number
    - name: ssl
      type: boolean

Anti-Patterns to Avoid

❌ DON’T: Use text fields for lists

# WRONG - Using multiline text for what should be a list
- name: allowed_values
  type: text
  lines: 5
  default: |
    - value1
    - value2
    - value3

✅ DO: Use proper list type

# CORRECT - Use type: list with listType
- name: allowed_values
  type: list
  listType: string
  default:
    - value1
    - value2
    - value3

Why this matters:

Lists provide structured data that’s easy to validate
Users get proper UI controls (add/remove buttons)
Code receives properly typed arrays, not strings that need parsing
Validation and error handling are automatic

❌ DON’T: Use text for structured data

# WRONG - Using text for object-like data
- name: config
  type: text
  default: |
    host: localhost
    port: 5432
    ssl: true

✅ DO: Use object type

# CORRECT - Use type: object with groupOptions
- name: config
  type: object
  groupOptions:
    - name: host
      type: string
      default: localhost
    - name: port
      type: number
      default: 5432
    - name: ssl
      type: boolean
      default: true

❌ DON’T: Mix default value structure with type

# WRONG - Default doesn't match list type
- name: items
  type: list
  listType: string
  default: "item1,item2,item3"  # Should be an array!

✅ DO: Match default structure to type

# CORRECT - Default is an array matching listType
- name: items
  type: list
  listType: string
  default:
    - item1
    - item2
    - item3

          - name: required
            type: boolean
            label: Required Field
            default: false

          - name: transformations
            type: list
            listType: string
            label: Transformations

            default:
              - trim
              - uppercase

Accessing this in code:

def __init__(self, options):
    # Get the processing config object
    config = options.get('processing_config', {})

    # Get string list
    allowed_types = config.get('allowed_file_types', [])
    # ['pdf', 'docx', 'txt']

    # Get nested object
    validation = config.get('validation_rules', {})
    min_size = validation.get('min_file_size', 1)
    max_size = validation.get('max_file_size', 50)

    # Get object list
    extraction_rules = config.get('extraction_rules', [])
    for rule in extraction_rules:
        field = rule.get('field_name')
        pattern = rule.get('pattern')
        required = rule.get('required', False)
        transforms = rule.get('transformations', [])

        # Process each rule
        self.add_extraction_rule(field, pattern, required, transforms)

Option Groups

Options can be nested into groups for better organization and user experience:

options:
  - name: database_settings
    type: object
    label: Database Settings
    description: Configure database connection
    properties:
      collapsible: true
    groupOptions:
      - name: host
        type: string
        label: Database Host
        required: true
        default: "localhost"
      - name: port
        type: number
        label: Database Port
        default: 5432
      - name: database_name
        type: string
        label: Database Name
        required: true
      - name: use_ssl
        type: boolean
        label: Use SSL Connection
        default: true

Benefits of grouping:

Organizes related options together
Can be made collapsible to reduce UI clutter
Creates a hierarchy of configuration
Improves user experience for complex configurations

Properties for groups:

collapsible: true - Makes the group expandable/collapsible in the UI

Providing Possible Values

Limit user input to specific choices using possibleValues:

- name: output_format
  type: string
  label: Output Format
  description: The format of the exported data
  possibleValues:
    - label: JSON
      value: json
    - label: CSV
      value: csv
    - label: Excel Spreadsheet
      value: xlsx
    - label: XML
      value: xml
  default: json

This creates a dropdown with only these four options. Users cannot enter free-form text.

Conditional Visibility

Use showIf to show/hide options based on other values:

options:
  - name: use_authentication
    type: boolean
    label: Require Authentication
    default: false

  - name: username
    type: string
    label: Username
    showIf: "this.use_authentication === true"

  - name: password
    type: string
    label: Password
    password: true
    showIf: "this.use_authentication === true"

The username and password options only appear when use_authentication is checked. showIf syntax:

JavaScript expression evaluated against current option values
Access other options via this.optionName
Supports boolean logic: &&, ||, !
Comparison operators: ===, !==, >, <, >=, <=

Complex example:

- name: deployment_type
  type: select
  label: Deployment Type
  possibleValues:
    - label: Cloud
      value: cloud
    - label: On-Premise
      value: on_premise

- name: cloud_region
  type: select
  label: Cloud Region
  showIf: "this.deployment_type === 'cloud'"
  possibleValues:
    - label: US East
      value: us_east
    - label: EU West
      value: eu_west

- name: server_address
  type: string
  label: Server Address
  showIf: "this.deployment_type === 'on_premise'"

Developer-Only Options

Hide advanced options from regular users:

- name: debug_logging
  type: boolean
  label: Enable Debug Logging
  description: Output detailed debug logs
  developerOnly: true
  default: false

Options marked with developerOnly: true are only visible to users who have enabled “Show Developer Tools” in their settings.

Feature Flags

Gate options behind feature flags:

- name: experimental_feature
  type: boolean
  label: Enable Experimental Feature
  description: Try out our new experimental feature
  featureFlag: experimental_features
  default: false

The option only appears if the specified feature flag is enabled for the project or organization.

Common Option Properties

All options support these common properties:

Property	Type	Description	Required
`name`	string	Unique identifier for the option	Yes
`type`	string	Option type (determines UI control)	Yes
`label`	string	User-facing display name	Yes
`description`	string	Help text explaining the option	Yes
`required`	boolean	Whether the value is mandatory	No (default: false)
`default`	any	Pre-filled default value	No
`possibleValues`	array	Allowed values (for select types)	No
`showIf`	string	JavaScript expression for conditional visibility	No
`developerOnly`	boolean	Only show to developers	No (default: false)
`featureFlag`	string	Feature flag that must be enabled	No
`properties`	object	Additional metadata (e.g., `collapsible`)	No

Best Practices

1. Provide Clear Labels and Descriptions

# Good
- name: max_retries
  label: Maximum Retry Attempts
  description: Number of times to retry failed operations before giving up. Set to 0 to disable retries.

# Poor
- name: max_retries
  label: Retries
  description: Max retries

2. Use Appropriate Types

Match the option type to the kind of data you’re collecting:

# Good
- name: port
  type: number
  min: 1
  max: 65535

# Poor
- name: port
  type: string

Important: For lists and structured data, use proper list and object types instead of text fields. See the Anti-Patterns section in “Working with Lists and Objects” for detailed examples.

3. Set Sensible Defaults

- name: timeout
  type: number
  label: Request Timeout (seconds)
  description: How long to wait for a response
  default: 30  # Most users won't need to change this
  min: 1
  max: 300

- name: connection_settings
  type: object
  label: Connection Settings
  properties:
    collapsible: true
  groupOptions:
    - name: host
      type: string
    - name: port
      type: number
    - name: timeout
      type: number

5. Use Required Judiciously

Only mark options as required: true if the component truly cannot function without them:

- name: api_key
  type: string
  label: API Key
  required: true  # Cannot work without this

- name: log_level
  type: select
  label: Log Level
  required: false  # Has a default
  default: info

6. Leverage Conditional Visibility

Keep the UI clean by hiding irrelevant options:

- name: use_proxy
  type: boolean
  label: Use HTTP Proxy
  default: false

- name: proxy_url
  type: string
  label: Proxy URL
  showIf: "this.use_proxy === true"

- name: proxy_username
  type: string
  label: Proxy Username
  showIf: "this.use_proxy === true"

Using Options in Code

Python (Assistants/Models)

class MyAssistant:
    def __init__(self, options):
        # Options are passed as a dictionary
        self.hostname = options.get('hostname')
        self.port = options.get('port', 22)  # With default
        self.use_ssl = options.get('use_ssl', False)

        # Nested options from groups
        db_settings = options.get('database_settings', {})
        self.db_host = db_settings.get('host', 'localhost')
        self.db_port = db_settings.get('port', 5432)

    def run(self, context):
        # Use the configured values
        connection = connect(
            host=self.hostname,
            port=self.port,
            ssl=self.use_ssl
        )

Validation Example

def __init__(self, options):
    # Validate required options
    if 'api_key' not in options:
        raise ValueError("api_key is required")

    # Validate value ranges
    timeout = options.get('timeout', 30)
    if timeout < 1 or timeout > 300:
        raise ValueError("timeout must be between 1 and 300")

    self.api_key = options['api_key']
    self.timeout = timeout

Summary

Options are Kodexa’s declarative configuration system. By defining options in metadata, you:

Enable user configuration without writing UI code
Provide type-safe input with automatic validation
Create consistent experiences across all components
Capture custom information tailored to your needs
Keep configuration co-located with component definitions

The Options system supports 24+ different types, from simple text inputs to complex taxonomy selectors with nested properties. Master options to build flexible, user-configurable components that integrate seamlessly into the Kodexa platform.
