Hi there. You can use the Wix iframe API to communicate between your React application and the parent Wix page. Whenever the height of the content within your React app changes, you can use the Wix.setHeight() method to dynamically adjust the height of the iframe. This way, the iframe will resize to fit the content and prevent any overflow. I once had help with these proble ms( link ). Al so You can apply CSS techniques to ensure that the height of the iframe adapts to the content. One approach is to set the height of the iframe container to 100vh (100% of the viewport height) using CSS. This will make the iframe take up the entire height of the viewport, regardless of the content. I hope some of this will help you.
