@stefrado I tried a CSS only solution first, but that won't work, since it's grids-inside-grids-inside grids...
+the Grids need to respond to having filters set on/off by municipalities, so this refactoring into columns might be the better solution. Other pages won't have this problem with multiple grids, but feel free to suggest better!
