I've been trying to figure this out for a while now... Basically, I have a custom field set up for a content type. More specifically, it's a category. (I'm not using taxonomy for long, drawn out reasons...) I've already got an attachment set up with filters and the like in Views. The attachment essentially prints out a subscription block and then "Recent Posts". What I'm trying to do is add all possible categories to the attachment, with a link that looks like this: http://mysite.com/blog/category_term. That link will then display all blog entries that have that particular category term associated with it. The thing is, it only pulls up the categories per entry and not all the categories available. Additionally, when I add it, it adds it beneath the title of the recent post, when what I want is something more like this:

Categories
A
B
C
D

Recent Posts
Hamburger
Cheeseburger
Big Mac
Whopper

I have played around with filters, arguments, etc., but can't for the life of me figure this out... Can anyone help me out?
