Hi, Hope all is well. I'm experimenting in migrating my existent hard-coded pages (such as https://www.emunations.com/genesis) towards using repeaters to eventually create DynamicPages. That said, the only issue encountered in the process is I can't stretch the ITEMs COLOR-BACKGROUND to the length of the page even though I'm well I can stretch Repeaters. Essentially, the page background is white and the background color of each item inside the Repeater should be greyish (as currently seen in the above URL). I usually create a ContainerBox inside the repeater and put all the contents but those Boxes aren't stretchable (see below): Thanks for your help!
