Good afternoon. I've got a bit of a usability question. I'm not sure where to ask it so I figured i would start here. I have dropdown single-select lists on a custom lightning component. I noticed the presence of arrows that go up and down (attached photo). I have to ask, what is the purpose of the arrows? During testing it confused some of our users that the arrow could be pressed to toggle the list. Needless to say, it does not do this so I'm wondering if its a visual queue that could be surpressed.@Lightning Components Development
