Rendering element multiple times on button Click

Question

I want to render a div component as many times a button is clicked in React JS, what should I use?

The task here was to add multiple input fields when i click the plus button, also can we use for loop here, to render elements ? This is the component I want to render multiple times on button click event:

import React from 'react'
import {Container,Col,Row,Table,Form,FormGroup,Label,Input} from 'reactstrap';
import 'bootstrap/dist/css/bootstrap.min.css';
export default function AddRemoveInputField(prop) {

    
  return (
    <div className='smallHr'>
        <div className="space"></div>
        <div><hr style={{width:
        '9rem',margin:'auto'}}/></div>
        <div className="space"></div>
        <FormGroup row>
                    <Label
                      for="exampleText"
                      sm={2} className='bold padding' 
                    >
                      Title
                    </Label>
                    <Col sm={10}>
                      <Input onChange={prop.action}
                        id="exampleText"
                        name="title"
                        type="text"
                      />
                    </Col>
                  </FormGroup>

      <FormGroup row>
                    <Label
                      for="exampleText"
                      sm={2} className='bold padding' 
                    >
                      URL
                    </Label>
                    <Col sm={10}>
                      <Input onChange={prop.action}
                        id="exampleText"
                        name="url"
                        type="text"
                      />
                    </Col>
                  </FormGroup>
                  <div className="space"></div>
                  <FormGroup row>
                  <Label 
                      for="exampleText"
                      sm={2} className='bold padding'
                    >
                      Discription
                    </Label>
                    <Col sm={10}>
                      <Input
                        id="exampleText"
                        name="discription"
                        type="textarea" onChange={prop.action}
                      />
                    </Col>
                  </FormGroup>
                  <div className="space"></div>
                  <FormGroup row>
                    <Label className='bold padding'
                      for="exampleText"
                      sm={2}
                    >
                      Source
                    </Label>
                    <Col sm={10}>
                      <Input onChange={prop.action}
                        id="exampleText"
                        name="source"
                        type="text"
                      />
                    </Col>
                  </FormGroup>
    </div>
  )
}```


The Component Looks Like This:

I tried using for loop in the Component, but it only rendered it once.

It comes down to simply using states to keep track of how many input elements your user needs, updating on demand, and map over the count to display.

Try something like

//declare this on your parent component
const [inputCounter, setInputCounter] = useState(0);
//Then pass the inputCounter and setInputCounter to your child (input)     
component as props
// Increment the value as plus button clicked
onClick={() => setInputCounter((prev) => prev++)}

// Go back to your parent component and loop over your counter
<div>
 {
   Array(inputCounter).fill(0).map((_, i) => <YourInputComponent />);
 }
</div>
