I'm guessing you're talking about interface elements that move with the screen? To do that, create a layer above all of your other layers and set the parallax values to 0. This will keep the layer in place while scrolling and you can put your interface elements on it.
Alternatively - and this is probably the best method if you're targeting multiple resolutions - you can add the anchor behavior to your interface objects. This will position them relative to the canvas based on where they were originally placed in the layout. This works better than the layer method because if you change the canvas size in game, all interface objects will adjust accordingly based on the edges of the screen they're bound to.
