adjustable ladder (SL1)

Hello everyone! Could anyone help me with an adjustable ladder that can be folded or collapsed so that it becomes compact enough to fit into a regular-sized car (like the one in the photo)? I’m looking for a ladder that can be used at different heights, but at the same time is easy to handle and store. If you know someone who has such a ladder, or if you have a recommendation on where I could find one, I would really appreciate it. Thank you very much for your help!
