Does X have any vertical accordian feature, I looked but didn’t see, or is there anything similar to this? see middle page on this example I was looking at, it’s not an X site but I was tasked to mimick on a X site. http://www.autodesk.com/products/fusion-360/overview
Thanks for writing in! X includes Tabs and Accordion. If you want something like your given URL, you need to use a third party plugin or achieve through custom development.
