    Create an image to a be the preview for list items without data.

    Then, do the following:

    1. Import the image to your application.

    2. Open the CSS Editor and create a new class to use the image as background.

      .task-list > script {                               
          background: url(...) !important;
          /* Drag and drop the image to set the URL of the image */

    3. Add the new CSS class to the Style Classes of the List widget.
