如何在 reactjs 中使用 onclick 事件渲染子组件？

Question

I want to render child component when I click the button
Parents

const Parents:React.FC<PropTypes> = ({inputs}) => {
  return(
    <div>
      <Button onClick={() => <Child props={inputs}/>}
    </div>
   )}

Child

const Child:React.FC<AnotherPropTypes> = ({props}) => {
  // ... 
}

I am using React, TypeScript and Material-UI for it.
My question is that, it does not seem like onClick event trigger Child component. How can I run child component when I click the button?
Any help appreciated!

Add state to your component. The click event sets the state, and the state is used to decide whether or not to render extra things.

const Parents:React.FC<PropTypes> = ({inputs}) => {
  const [showChild, setShowChild] = useState(false);
  return(
    <div>
      <Button onClick={() => setShowChild(true)} />
      {showChild && <Child props={inputs}/>}
    </div>
  )
}
