Be able to add background behind visualchoice about renjs-v2 HOT 1 CLOSED

I think it's too specific, but you can do this by adding a transition for the visualChoices with a plugin:
The transition for visual choices will receive a display object where each child is one of the visual choices elements, so you'd need to loop its children to add the background. Something like this:

from,to =>
(if hiding)
if !to return FADE (or any other transition you want to use)
(if showing)
for child in to.children:
create background
add background to "to" in correct position
send child to front (this is to make sure child will be on top of background)
return FADE (or any other transition you want)

That's more or less what the transition should do, then you set this transition as the default transition for visual choices. Check this to see how to add new transitions.
