Here is what I want to do, I don't mean to advertise but it's easier if you just have a look here. See the "categories" menu on the side? Just underneath I want to add another menu labeled "manufacturers" so people can browse my posts by company name such as magellan, garmin, etc...?
And I want to be able to pick a manufacturer from admin side just like I pick a category when I'm writing posts.
There must be plug-in for this? Anyone?
