Editing Items

Basic Usage

import React from 'react';
import ReactDOM from 'react-dom';
import { ReactFormBuilder } from 'react-form-builder2';
import 'react-form-builder2/dist/app.css';

ReactDOM.render(
  ,
  document.body
)

Props

var items = [{
  key: 'Header',
  name: 'Header Text',
  icon: 'fa fa-header',
  static: true,
  content: 'Placeholder Text...'
},
{
  key: 'Paragraph',
  name: 'Paragraph',
  static: true,
  icon: 'fa fa-paragraph',
  content: 'Placeholder Text...'
}];

React Form Generator

Now that a form is built and saved, let's generate it from the saved json.

import React from 'react';
import ReactDOM from 'react-dom';
import { ReactFormGenerator } from 'react-form-builder2';
import 'react-form-builder2/dist/app.css';

ReactDOM.render(
  ,
  document.body
)

Form Params

Read only Signatures

Read only signatures allow you to use a saved/canned signature to be placed into the form. The signature will be passed in through the variables property to ReactFormGenerator and ReactFormBuilder.

To use a read only signature, choose the "Read only" option and enter the key value of the variable that will be used to pass in the signature.

The signature data should be in base 64 format.

There is a variables.js file that contains a sample base 64 signature. This variable is passed into the demo builder and generator for testing. Use the variable key "JOHN" to test the variable replacement.

Vendor Dependencies

In order to make the form builder look pretty, there are a few dependencies other than React. Style sheets from Bootstrap and FontAwesome must be added to index.html. See the example code in index.html for more details.

• Bootstrap
• FontAwesome

SASS

All relevant styles located in css/application.css.scss.

Develop

$ yarn install
$ yarn run build:dist
$ yarn run serve:api
$ yarn start

Then navigate to https://localhost:8080/ in your browser and you should be able to see the form builder in action.

Customizations

• to customize the field edit form copy "src/form-elements-edit.jsx" to your project and pass it to the ReactFormBuilder as a prop. Here is an example

 }
/>

• to customize the ReactFormGenerator submit button use it like this

Submit}
    backButton={<a href="/">Back</a>}
/&gt;

Custom Components

• Import component registry from react-form-builder2

import { ReactFormBuilder, ElementStore, Registry } from 'react-form-builder2';

• Simple Custom Component

const TestComponent = () =&gt; <h2>Hello</h2>;

• Custom Component with input element

const MyInput = React.forwardRef((props, ref) => {
  const { name, defaultValue, disabled } = props;
  return <input disabled="{disabled}" name="{name}">;
});

• Register custom components to be used in form builder

Registry.register('MyInput', MyInput);
Registry.register('TestComponent', TestComponent);

• Define Custom Components in Toolbar

const items = [{
  key: 'TestComponent',
  element: 'CustomElement',
  component: TestComponent,
  type: 'custom',
  field_name: 'test_component',
  name: 'Something You Want',
  icon: 'fa fa-cog',
  static: true,
  props: { test: 'test_comp' },
  label: 'Label Test',
}, {
  key: 'MyInput',
  element: 'CustomElement',
  component: MyInput,
  type: 'custom',
  forwardRef: true,
  field_name: 'my_input_',
  name: 'My Input',
  icon: 'fa fa-cog',
  props: { test: 'test_input' },
  label: 'Label Input',
}, 
// Additional standard components, you don't need full definition if no modification is required. 
{  
  key: 'Header',
}, {
  key: 'TextInput',
}, {
  key: 'TextArea',
}, {
  key: 'RadioButtons',
}, {
  key: 'Checkboxes',
}, {
  key: 'Image',
}];
