Yes, absolutely, and UX experts such as those at the Nielsen-Norman group have for years been advising against auto-closing the already-opened options when opening another. For good reason - user frustration in their research.

If I clicked it to open it, then if I want to close it, I'll click it again. Don't hide content I might still be reading!

When a form has two sets of mutually exclusive options it might be appropriate? But I find the user experience confusing. It's hard to tell what happened when all the elements moved around, at least without animations.

Skimming/scanning. For a couple of items, it is not an issue, but say for a long list of FAQ, being able to scroll past fast is nice.

but then just close the elements yourself if you need that? don't force one behavior onto everyone

Most people are lazy, so it is designed for most, including myself.
