I feel like this should be very simple, but I'm struggling with it.
How can I place things inside other objects after they've been placed?
For example, I placed my map first and want to place it in my sidebar, which I just added

How can I do this? I thought maybe dragging it in on the main screen would work, but that doesn't seem to do it for me.
I'm really surprised that experience builder is like the one place in the Arc environment where you can't click and drag in the table of contents to re-order things.
