How to Add Additional Content to the Image Upload Dialog in React Rich Text Editor Component

This article provides guidance on how to include additional content in the image upload dialog of the Rich Text Editor Component. This customization is particularly useful when specific information needs to be displayed to users during the image upload process.

Customizing the Image Upload Dialog

To include additional content in the image upload dialog of the RichTextEditor Component, use the dialogOpen event. Follow the approach below:

<RichTextEditorComponent
  toolbarSettings={toolbarSettings}
  insertImageSettings={insertImageSettings}
  imageUploading={onImageUploading.bind(this)}
  dialogOpen={onDialogOpen}
>
  <Inject
    services={[Toolbar, Count, Image, Link, HtmlEditor, QuickToolbar]}
  />
</RichTextEditorComponent>

function onDialogOpen(args) {
  const linkHeader = args.container.querySelector('.e-linkheader');

  if (linkHeader) {
    // Create and configure the new div element
    const infoDiv = document.createElement('div');
    infoDiv.textContent =
      'Allowed file types are .png, .jpeg, .jpg, and .gif, and the maximum file size is 10 MB';
    infoDiv.classList.add('image-dialog-info');

    // Insert the new div after the linkHeader element
    linkHeader.parentNode.insertBefore(infoDiv, linkHeader.nextSibling);
  }
}
