Another option is to build it with code. Here you can find a step-by-step tutorial to learn how to add custom code to create an infinite horizontal scrolling text animation: https://www.editorx.com/academy/from-x-team/infinite-auto-scroll
In this example we are using running text, but it can work for any type of element.
