Portals – React

These docs are old and won’t be updated. Go to react.dev for the new React docs. These new documentation pages teach modern React and include live examples: createPortal Portals provide a first-class way to render children into a DOM node that exists outside the DOM hierarchy of the parent component. The first argument (child) is any renderable React child, such as an element, string, or fragment.
