I am working on a site that will need a checklist of sorts where i can categorize items into different lists and then users can then check off which items they have, enabling them to have two different lists, what they have and what they need to get. I've seen many book mods, and they are much like what i want, but they are specified for books only. What i am looking for would be something where i could name type of item being collected and the different items in that category. Can anyone help?
