Trying the "Interactive Legend" one right now, and it doesn't seem to support the groups. All the layers in the groups just don't show it seems? The only layers available are the ones not in a group.
Can you tell me what this means? 4.x?
I have a non mapbeta webmap that I published using webapp builder with the foldable theme and I'd like to convert it into something that can group layers preferably without changing the web address of my existing app. Is this possible? The TOC is a mess and I really want to clean it up so I can add more data.
