My idea is to create 2 states, one for each button, they will have the number of the divs needed for each tag.

const [textAreaNo,setTextAreaNo] = useState(0);
const [uploadNo,setUploadNo] = useState(0);

then after your buttons you can call the (addDiv) function, but u will have to create 2 different functions for each button, or just make one function and inside the function it will return upload or textArea depending on the passed parameter.

then finally you need to use map like this

{[...Array(textAreaNo)].map(e=>(
    <div> textbox <div>
  ))}

and on your button we will just increment the states above like

 <button onClick={()=> setTextAreaNo(textAreaNo+1)}>AddDivs</button>

I'm not sure if you want to be able to add multiple text areas. A way I would do it, is to create a state item that knows how many text areas you need, and then a function that increases this number on the onClick(). You will also need a function that returns the text box item. Something like this:

Class Component:

this.state = {
    numberOfTextAreas: 0
}

const textAreas = () => { //<---------a function like this

for (let i = 0; i < this.state.numberOfTextAreas; i++) {
    return (
        <div>
           <textarea rows="4" placeholder="Write about sompething here..." /> 
        </div>
    );
}
}

const addDivs = (type) => { ??? }

export default function Form() {

handleSubmit(e) {...}

return ( 
<form onSubmit={handleSubmit}>
<div><textarea rows="4" placeholder="Write about something here..." /></div>


//New divs should go here
{textAreas} //<---- Add this here.


<button onClick={() => this.setState({numberOfTextAreas + 1})}>Add textarea</button>
//Adds an upload field
<button onClick={() => addDivs(upload)}>Add image</button>
<input type="submit" value="Submit" /> </form> ); 
}

```

Then you'll just want to do the same with the other types you are wanting to create.
