Saving checklist state

I’m trying to create a checklist on my site.
I want the site to “remember” what boxes were checked by the user.
I guess it’s done with cookies but I’m very not technical, so I’m not even sure what to look in google.

I found this site by webflow itself, and this is pretty much what I’m aiming to achieve:
the checkboxes state is still there, even after I leave the site or refresh it.

This is the basic feature you’re talking about, but I need to expand it in a few ways to cover your specific use case.

Have a look at it and I’ll think about how to best expand the feature set while I’m on vacation this week.
