Hi All,
I tried using the triblock-side-nav layout, tried applying the background image to the layout, there is only option we can add the background color, in documentation also we don't have option for background image. any hack/ways we can use the background image for the side-nav layout.
documentation reference : (https://aggiefacilities-dev.tririga.com/p/web/doc?polymerVersion=3#!/triblock-side-nav/)
