How to limit attributes displayed on pop-up?

Question

I am using Web AppBuilder Developer Edition 2.0.

I am using Robert's PopUp Widget. Works great! However, I want to limit the number of attributes displayed, currently, when a feature is clicked on, all the attributes in the attribute table display, how do I, for example, limit this to display only 3 or 4 attributes of my choosing?

Tim,

Popup attributes are configured for the layer in the Web Map in AGOL.
