import { Html } from 'react-konva-utils';

<Html
  transform // should we apply position transform automatically to DOM container, default is true
  transformFunc={(transformAttrs) => newAttrs} // function to overwrite transformation attributes, not used if transform = false, default is undefined
  groupProps={{}} // additional properties to the group wrapper, useful for some position offset
  divProps={{}} // additional props for wrapped div elements, useful for styles
  parentNodeFunc={(args) => args.stage?.container()} // function to find parent node to insert content, default is stage container
>
  <div>DOM content</div>
</Html>;

How does it work?

Konva is a canvas library. It can't render DOM elements directly. <Html> component will just create a div element and put it top top of the canvas with absolute positioning. That means HTML will be not visible if you export canvas as image.

The most common use case is to create HTML content for temporary tooltips or textareas.

Portal

Portal allows you to create portal from one Konva container (such as Layer or Group) into another.

import { Portal } from 'react-konva-utils';

<Layer>
  <Portal selector=".top">
    {/* content of that portal will be moved into "top" group*/}
    <Rect width={100} height={100} fill="red" draggable />
  </Portal>
  <Rect width={100} height={100} fill="black" draggable />
  <Group name="top" />
</Layer>;
