PortalHostCell

Optional shape that a dia.Cell subclass can implement to opt into joint-react's portal rendering. Cells without a portalSelector are skipped by default (unless a paper-level override is supplied).

ElementModel and LinkModel satisfy this structurally; custom cell classes can too:

import type { PortalHostCell } from '@joint/react';

class MyShape extends dia.Element implements PortalHostCell {
  portalSelector = 'root';
}

Properties

portalSelector?

readonly optional portalSelector?: string;

Selector of the node inside the cell view where React content mounts.
