This is a parameter that exists in the tag family template.
The concept is simple, check it when you want the tag to align itself with the component you tag. Example...a door. Works nicely.
Yet when you attempt to use it with other categories you can check it all night long and it does nothing...example a light fixture.
Some tags are hard wired to not use it while others are. We either need a list of the categories it is intended to work with or better yet, make it work for all content! It is so very frustrating for users to get so close yet have something like this trip them up!
