1let formGrid =
2	[
3			[

11			],
12			[
13				{type: "radio", label: "Male", key: "6", id: "gender", name: "gender", value: "male"},
14				{type: "radio", label: "Female", key: "7", id: "gender", name: "gender", value: "female"}

submitButton:

For developers freedom, here is an option of designing submit button. This is an object and should have two key-pair value, name and className (bootstrap 4 className)

1let submitBtnInfo = {
2	name: "Submit",
3	className: "btn btn-outline-primary btn-md float-right"
4}

onSubmit:

This functionality also developed for developers freedom. This is an handler function and should be defined as asynchronous. This function receive data from form submit and provide developer for further use. You can send data asynchronously from here.

1const handleSubmit = async data => {
2	console.log("On Submit Method Called");
3	console.log(data);
4};

initialValue:

This is a state management system. This package provide user a state and it will update dynamically when there will any change in form. To define initialValue, Be careful about your field name. This is an object with key-value pair. key is the name attribute of fields. Every name of your fields Props should be entry here as key-value pair. value is your choice. But if you provide a field without entry here, Package will complain.

1
2let initialState = {
3	firstname : "Shohidul",
4	lastname : "Bari",
5	city : "Dhaka",
6	age : undefined,
7	address: undefined,
8	gender: "male",
9	profession: ["engineer"]
10}

Now use it in your component:

1import FormKit from "react-bootstrap-formkit";
2function App() {
3
4return (
5	<div className="App">
6		<div className="container">
7			<FormKit
8				fields={formGrid}
9				submitButton = {submitBtnInfo}
10				onSubmit = {handleSubmit}
11				initialValue = {initialState}
12			/>
13		</div>
14	</div>
15);
16}
