In ArcGIS Online Experience Builder, I want the layer List/Legend to be open on load of my app. Is there a way to do this that I am missing?
Not with the Layer tool built into the Map Widget, but if you build your own, it can be open by default.
@RossFindlayCOC In the Map Layers widget, there is an option if you turn on the legend - "Show legend for all visible layers by default":
Is this something you are looking for?
I use a section with a views navigation to keep it open upon loading.
