Chakra UI is a popular UI library for React that provides a set of accessible and customizable components. One of the useful components it offers is the “Portal” component, which allows you to render a component’s children outside of its parent DOM hierarchy. This can be particularly useful when you want to render a component at the top level of the application, such as modals, tooltips, or dropdown menus.

Why use the Portal component?

The Portal component in Chakra UI offers several benefits:

1. Accessibility: It ensures that the portal content is still accessible to screen readers and other assistive technologies.

2. Prevents CSS Clashing: By rendering content outside of the parent DOM hierarchy, it prevents CSS clashes that may occur when applying styles to parent and child components.

3. Z-Index Management: When rendering content at the top level, you can easily manage the z-index to control the stacking order of elements.

How to use the Portal component in Chakra UI

Using the Portal component in Chakra UI is straightforward. Here’s an example of how to use it:

import { Portal } from "@chakra-ui/react";

function App() {
  return (
    <div>
      <h1>My App</h1>
      <Portal>
        <div>Rendered outside the parent div</div>
      </Portal>
    </div>
  );
}

In the example above, we import the Portal component from the @chakra-ui/react package and wrap the content we want to render outside of the parent div with the Portal component. The content will be rendered as a sibling of the root div where the ChakraProvider is rendered.

It’s important to note that the Portal component does not accept a parent prop. Instead, it detects the nearest ChakraProvider component as the parent.

Conclusion

The Portal component in Chakra UI is a powerful tool for rendering components outside of the parent DOM hierarchy. It provides accessibility, prevents CSS clashes, and makes z-index management easier. By using the Portal component, you can create more flexible and interactive UI components in your React applications.
