Last week, I spoke with @MichaelGaigg. He showed me how to use a Hosted Table with a List Widget and Data Views to hide and unhide items in Experience Builder. He also showed how to use a solid color image to make a dynamically changing background. This tip has also been discovered by @AlderMaps. And @Christina_Appleby and @KaraUtter2, have previously demonstrated using a Hosted Table with a List Widget to combine text and images. Let's put all these ideas together and create a set of links that can be perpetually and dynamically updated from outside Experience Builder.
Note to users of ArcGIS Enterprise: I will be using the recent history of social media as a narrative framing device. None of the Experience Builder options described here are particularly new, but depending on your version number some of them may be missing. We will be traveling back in time to before the first release of Experience Builder, so if your Enterprise is that old. No, this won't work for you.
