Q: How do I get categories bar to show at the top?

A:
In 1.5.x, a new category bar was added, allowing you to choose which categories show in the top bar.

If you've upgraded from 1.4.x to 1.5.x, you probably don't see it at all because you haven't assigned any categories.

1. Edit a category in the admin area
2. On the "Data" tab, check the "Top" checkbox
That's it!
Now you will see the category on the top bar. Do the same for other categories.
