Override content widget configuration

Typically, you configure the content and appearance settings for a content personalization widget in the Customer Engagement Console (CEC). For banner and HTML block widgets, this can include URLs, text and HTML.

To override CEC configuration of a banner widget whose rfkId is banner_2:

In the CEC, in the Merchandising Widgets section, in the Widgets tab, find the banner widget and note its rfkId.

In your React project, in the widget_components folder, create a file called temporaryBanner.js, and paste the following code block.

import {
  useContentBlock,
  useWidgetVisibility,
  widget,
  WidgetDataType,
} from "@sitecore-discover/react";
import { createElement, useLayoutEffect, useRef } from "react";

function addStyle(rfkId, node, css) {
  let styleNode = document.querySelector(`[data-rfk-id-style=${rfkId}]`);
  if (!styleNode) {
    styleNode = document.createElement("style");
    styleNode.setAttribute("type", "text/css");
    styleNode.dataset.rfkIdStyle = rfkId;
    node.parentNode?.appendChild(styleNode);

  styleNode.innerHTML = css;

export default widget(ContentBlockWidget, WidgetDataType.CONTENT_BLOCK);

Import and add the widget component to your application or page component.
