How to have a different background image in each submenu?

How to have a different background image in each submenu?
I have 5 views in the footer. I would like to have a different background image for each site. How do I do this?
I have find that when the view type comes to “detail”, I can set the custom background. But when the view type comes to other kind beyond the “detail”, how can I set the background?

I’m afraid this isn’t possible. :frowning:

Thank you kindly, I am afraid it just can be realized by linking related app.

:confused:
