Form Structure (3-Level Hierarchy)

ApplicationForm
  └── Section (FormElementSection)
       ├── title, shortTitle, description
       ├── isTemplate, templateReference, titleTemplate  ← for spawning
       └── SubSection (FormElementSubSection)
            └── FormElement
                 ├── id (UUID), reference (string key)
                 ├── type: SELECT | CHECKBOX | RADIOBUTTON | TEXTFIELD | TEXTAREA | SWITCH | RICH_TEXT | DATE | TABLE
                 ├── options: FormOption[] (value, label, processingPurpose, employeeDataCategory, columnConfig)
                 ├── visibilityConditions[] (AND logic)
                 ├── sectionSpawnTriggers[]
                 ├── isClonable, tableRowPreset

Key Features

Visibility Conditions

• Elements shown/hidden based on other element values
• Multiple conditions use AND logic
• Operators: EQUALS, NOT_EQUALS, IS_EMPTY, IS_NOT_EMPTY
• Reference elements by reference key (not ID)
• Hidden elements: excluded from validation, PDF export, and values cleared

Section Spawning

• Template sections (isTemplate: true) spawn when trigger conditions met
• Title interpolation: {{triggerValue}} placeholder
• Spawned sections linked via spawnedFromElementReference
• One element can have multiple sectionSpawnTriggers

Clonable Elements

• isClonable: true shows "Add another" button
• Deep cloning with auto-generated references (modul_1 → modul_2)
• Values reset on clone (TEXTAREA/TEXTFIELD)

Table Cross-References

• Column references other table's column: columnConfig.sourceTableReference
• Row presets from source table: tableRowPreset
• Filter conditions limit available values

Roles (Keycloak-managed)

CHIEF_EXECUTIVE_OFFICER, BUSINESS_DEPARTMENT, IT_DEPARTMENT, HUMAN_RESOURCES, HEAD_OF_WORKS_COUNCIL, WORKS_COUNCIL, EMPLOYEE

Development

# Frontend (port 3001)
cd legalconsenthub && pnpm install && pnpm run dev

# Backend (port 8080)
cd legalconsenthub-backend && ./gradlew bootRun

# Generate API clients (after modifying api/legalconsenthub.yml)
pnpm run api:generate                    # Frontend client
./gradlew generate_legalconsenthub_server # Backend server stubs

Key Files

File	Purpose
api/legalconsenthub.yml	OpenAPI spec (source of truth)
.github/workflows/pipeline.yaml	CI/CD workflow

See subproject CLAUDE.md files for component-specific key files.

Rules for AI

1. API-first workflow - Always modify OpenAPI spec first, then regenerate clients
2. Organization context - Always consider organizationId for multi-tenancy. Forms with empty/null organizationId are "global" forms visible to all organizations
3. Form structure is 3-level - Section → SubSection → Element
4. Roles managed in Keycloak - Not in application database
5. Subproject-specific rules - See CLAUDE.md files in each subproject directory

Code Style

• Order functions top-down by abstraction (public API first, helpers below)
• Keep CLAUDE.md files updated when introducing architectural changes
