Adding a Div Inside a Text Input in React
No, you cannot directly insert a <div> or any other HTML element inside an <input> or <textarea> in React (or standard HTML) because:
Input elements are void elements - They can't contain children in the HTML specification
Textarea only accepts text - The <textarea> element is designed solely for plain text content
Alternative Solutions
1. ContentEditable Div function RichTextInput() {
  const [content, setContent] = useState('');
  return (
    <div 
      contentEditable 
      dangerouslySetInnerHTML={{ __html: content }}
      onInput={(e) => setContent(e.currentTarget.innerHTML)}
      style={{
        border: '1px solid #ccc',
        padding: '8px',
        minHeight: '100px'
      }}
    />
  );
}
