The MUI Fade component specializes in showcasing, concealing, and transitioning components without any fading effects

I have recently made a change in my code where I replaced conditional rendering of child components with wrapping them in <Fade />. However, the Fade effect does not seem to work as both components always display. Below is the updated code snippet:

// within the main component
{/*{adminView === bodyViews.addNewCoupon &&*/
<Fade
  in={Boolean(adminView === bodyViews.addNewCoupon)}
  timeout={2000}
>
  <AddCouponForm />
</Fade>
{/*}*/}
  
{/*{adminView === bodyViews.viewCurrentCoupons &&*/
<Fade
  in={Boolean(adminView === bodyViews.viewCurrentCoupons)}
  timeout={2000}
>
  <ViewCoupons />
</Fade>
{/*}*/}

Referring to the API documentation available here, setting in to true should trigger the fading effect for the component. While this worked in the previous version with conditional rendering, it seems that using it directly within the in attribute does not produce the expected outcome. What could be causing this issue?

Update:

I noticed that when I comment out the custom components and replace them with something simple like <p>Section 1/2</p>, the fade effect works correctly. There appears to be something specific to the custom components that prevents the Fade effect from working properly.

The problem was identified specifically with Custom components: they do not function properly as direct descendants of <Fade />. The issue has been resolved by enclosing the custom component children in a div.

  <Fade
    in={ Boolean(adminView === bodyViews.addNewCoupon) }
    timeout={ 4000 }
  >
    <div>
      <AddCouponForm />
    </div>
  </Fade>     

  <Fade
    in={ Boolean(adminView === bodyViews.viewCurrentCoupons) }
    timeout={ 4000 }
  >
    <div>
      <p>Section 2</p>
      <ViewCoupons />
    </div>
  </Fade>

Additionally, it appears that Fade encounters issues when there are multiple children. Thus, all children should be contained within a single div element.

Transition allows the child component to be updated using the styles prop. If you are working with a custom component, it is important to pass down the props from Transition by forwarding the ref to the child:

const CustomComponent = React.forwardRef((props, ref) => {
  return (
    <div {...props} ref={ref}>
      custom component
    </div>
  );
});

<Transition in={checked}>
  <CustomComponent />
</Transition>
