Configuration

Form Configuration

The form configuration object (FormConfig) has three main sections:

1. form - General form settings
2. sections - Form sections
3. questions - Form questions

Form Settings

interface FormStyle {
  style: "tabs" | "subheadings";
  showHeader: boolean;
  headerTitle: string;
  headerSubTitle: string;
  buttons: {
    primary: ButtonStyle;
    secondary: ButtonStyle;
  };
}

Section Configuration

interface Section {
  section_id: string;
  section_name: string;
  order: number;
  description: string;
  showHeader?: boolean;
}

Question Configuration

interface Question {
  question_id: string;
  question_text: string;
  question_style: string;
  mandatory: "yes" | "no";
  validations: ValidationRule[];
  dependency_question_id: string;
  dependency_answers: string[];
  placeholder_text: string;
  help_text: string;
  default_value: any;
  order: number;
  field_width: "full" | "half";
  section_id: string;
  visibility: "visible" | "hidden";
  options?: Option[];
}

Validation

Add validation rules to questions:

validations: [
  {
    pattern: "^[A-Za-z\\s]+$",
    error_message: "Only letters are allowed"
  },
  {
    pattern: "^.{3,}$",
    error_message: "Minimum 3 characters required"
  }
]

Conditional Logic

Make questions appear based on other answers:

{
  question_id: "has_pet",
  question_text: "Do you have a pet?",
  question_style: "checkbox",
  // ...
},
{
  question_id: "pet_name",
  question_text: "What's your pet's name?",
  question_style: "text",
  dependency_question_id: "has_pet",
  dependency_answers: [true],
  // ...
}

Styling

The form uses Tailwind CSS for styling. You can customize the appearance by:

1. Using your own Tailwind configuration
2. Customizing the button styles in the form config
3. Overriding CSS classes

TypeScript Support

The package includes full TypeScript definitions. Import types:

import type { 
  FormConfig,
  FormData,
  Question,
  Section,
  ValidationRule,
  Option
} from 'react-dynamic-form-builder';
