Overview
The React Form Builder is a visual form designer for creating dynamic forms with a drag-and-drop interface. Configure built-in and custom components, validations, conditional logic, expressions, and dependent fields, then preview the form and generate its JSON-based form schema for reuse.
Why choose the Syncfusion React Form Builder?
Drag-and-drop design
Build form layouts by dragging fields into the design area and rearranging them to match your required form structure.
Built-in components
Choose from 20+ built-in form components for text, selection, date, rating, signature, file upload, and more inputs.
Custom components
Register custom components to add specialized fields and application-specific inputs beyond the built-in options.
Field configuration
Configure field names, labels, placeholders, validation rules, and other properties through the properties panel.
Conditional logic
Define conditions to show, hide, enable, or disable form fields based on values entered in other fields during runtime.
Expressions
Use expressions to calculate field values and update related form fields automatically when other form values change.
Form preview
Preview the designed form to verify its layout, field behavior, validations, conditions, and overall runtime flow.
Responsive rendering
Create responsive forms that adapt to desktop, tablet, and mobile screen sizes while preserving layout and usability.
React Form Builder code example
Easily get started with the React Form Builder using a few simple lines of TSX code, as demonstrated. Also explore this React Form Builder example, which shows you how to design forms.
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { FormBuilderComponent } from '@syncfusion/ej2-react-form-builder';
export default class App extends React.Component<{}, {}> {
public render(){
return (
<FormBuilderComponent />
);
}
}
ReactDOM.render(<App />, document.getElementById('formbuilder'));JSON schema form design
Design forms visually and generate the JSON schema that defines fields, layout, conditions, expressions, and behavior. The generated JSON schema can be used to display forms using the React Form Renderer control.
Validations
Apply a comprehensive set of validation rules to ensure that the data captured from users is accurate, consistent, and complete. Built-in rules include required, email, URL, date, number, and length, along with custom validation strings for business-specific logic.
Expressions
Define calculations, derived display text, and computed field values that update instantly while the form is in use. Expressions are declared directly in the JSON schema, so the preview evaluates them automatically, eliminating manual event wiring and custom code.
Conditions
Drive dynamic form behavior with conditional rules defined in the schema. Show, hide, make read only, or disable fields and sections based on the values of other fields, or any expression, so the form adapts to the context of each user without custom script actions.
Dependent dropdowns
Build cascading dropdowns and other dependent form fields by wiring one control’s value to another through simple schema declarations. Common scenarios such as country–state, category–subcategory, and department–employee lists can be configured without writing any code.
Code view
Switch to the code view to inspect the JSON schema generated for the drag-and-drop form. The generated schema makes it easy to understand, validate, version, and reuse the underlying form definition across the application.
Form preview
Preview the designed form at any time to see exactly how it will appear and behave at runtime before saving or publishing it. Interact with fields; test validations, expressions, and conditional rules; and fine-tune the layout without writing any code.
Accessibility
Keyboard navigation
Every interactive element can be reached and operated using just the keyboard. Users can tab between fields, configure validations, and navigate within the control without needing a mouse, making it easy to build forms that are accessible to all users.
Screen readers
The component produces WAI-ARIA-compliant markup so that every field, label, and property item is announced clearly by modern screen readers. This helps users with visual impairments complete the form accurately and independently.
Right to left (RTL)
Render forms in right-to-left mode for languages such as Arabic, Hebrew, and Persian. It automatically mirrors the layout, alignment, and icons of all controls so that the component looks natural and is easy to use for RTL users.
