Creating cool navigation utilities is a snap with Views. This post will focus on my efforts to put together a view that outputs a list of groups that are in the same category as the group we are currently looking at.
I believe this would be possible with contexts in panels however I am looking to build just a single block that I can do with as I please.
Step 1: To get started I navigate to the views administration screen at /admin/build/views and create a new view named group_navigation.
