Is there a way to hide hotbars when not in combat?

I think it's part of the transparency settings. Can't confirm, as I'm currently at work, but it might be that. Or it might just affect when in combat and holding either L2/R2, and the opposite one can be made invisible. My minds aa bit fuzzy on it right now.

Nope, they just turned the element invisible. Crosshotbar doesn't have a transparency setting. Also, it doesn't change when in or out of combat and shows the whole crosshotbar regardless of which button is pressed.
