CMS Made Simple Forums

I'm using Listit2 to display categories, and items within categories.

I'm trying to show categories on their own, but when I use the Listit2 tag, all the categories are displayed by default, even if I try to show a specific category, all the categories will still show.

Can someone help?

Could you post (part of) page template where you call LI2?

And the relevant LI2 templates.
