An empty tile type to display nothing?

[TransGirlCodes]

Hi,

I have a basic interactive UI element, here a checkbox is initially false, and when ticked, allows two other text input boxes to be shown for user interaction, of course this goes into a main(window) function body:

use_windows = Signal(false)
    window_check = checkbox("Use sliding windows") >>> use_windows
    wsize = textinput("100", label = "Window size")
    wstep = textinput("100", label = "Window step")
    window_box = map(use_windows) do val
        vbox(
        window_check,
        if val
            hbox(wsize, wstep)
        end
        )
    end

However in my rendered web ui, when the box is unticked - hiding the two text inputs, the word 'nothing' is printed underneath. I wondered if to solve this there is some blank tile which draws nothing is available for me to add as an else clause?

Thanks for Escher, I'm enjoying it very much, Ben.
