I understand, thanks for posting more info. This is definitely possible, but I'm skeptical of the user experience. I say this because once you mouseover a feature name, it shows up on the map but as you mouse out, it disappears. How is a user supposed to get more info about a feature?I guess if you just need to show the feature but don't need to let the user interact with it, this would be a valid workflow. Here's a simple implementation:
