Experience Builder, PopUp, interaction with two layers

[Greta]

I am using Experience Builder. I am new to it, but I would like to do the following: I have a list of suburbs and a list of flood events. If I press the button Suburb and Probable Maximum Flood, the popup message should appear with the suburb's name and the description of the flood event. If I only press the flood event only should appear the description of the flood in the popup. Is there a way to do it using Experience Builder? Is any other method available in ArcGIS Online?

Thanks

Hi Greta, 

I think you can insert two expressions in the text widget, one is for the suburb name and the other is for the flood description. The name for both expressions could be blank space (so no strings will show when no selection is made).  Please refer to the following screenshots.
