On this Demo grid with sortable tiles via dragging, I'm not sure how one would put content into the tiles, I tried a few obvious things but there must be something I'm missing. This is becoming a theme for me here at GSAP - i always seem to be missing one key element that has no mention or reference anywhere - surely it's not intended to be a page of numbered green tiles...
If anyone can point me in the right direction, please let me know. I'd like to try it as an image gallery...
