Portal

Renders a component outside the current DOM hierarchy.

Import#

import { Portal } from "@nature-ui/core";

Usage#

Portal is used to transport any component or element to the end of document.body and renders a React tree into it.

Useful for rendering a natural React element hierarchy with a different DOM hierarchy to prevent parent styles from clipping or hiding content (for popovers, dropdowns, and modals). It supports nested portals

function Example() {
  return (
    <Box className="bg-red-400 text-white">
      I'm here,
      <Portal>This text is portaled at the end of document.body!</Portal>
    </Box>
  );
}

Using a custom container#

You can render the contents within a portal to a different DOM node, instead of the default document.body. Pass the containerRef prop and set its value to the ref of the container you'd like to use.

function Example() {
  const ref = React.useRef();
  return (
    <Box className="bg-red-400 text-white">
      I'm here,
      <Portal containerRef={ref}>
        Portal: This text is portaled to the yellow box!
      </Portal>
      <Box ref={ref} className="bg-yellow-500">
        <div>Container: Hey,</div>
      </Box>
    </Box>
  );
}

Nesting Portals#

You can also nest multiple portals within themselves, this will create a nested DOM hierarchy to make it easy to create nested modals, popovers, etc.

function Example() {
  const ref = React.useRef();
  return (
    <div>
      <Portal containerRef={ref}>
        <Box className="text-white bg-teal-500">
          Parent: Hey welcome,
          <Portal>Child: I'm attached to my parent portal</Portal>
        </Box>
      </Portal>
      <Box className="text-white bg-red-500" ref={ref} />
    </div>
  );
}

Opting out of portal nesting#

In some cases, you might not want portal nodes to be nested to their parent portals. To opt out of this, pass appendToParentPortal and set it to false

function Example() {
  const ref = React.useRef();
  return (
    <div>
      <Portal containerRef={ref}>
        <Box className="text-white bg-teal-500">
          Parent: Hey welcome,
          <Portal appendToParentPortal={false}>
            Child: I'm going to document.body
          </Portal>
        </Box>
      </Portal>
      <div style={{ background: "red" }} ref={ref} />
    </div>
  );
}
