I was unable to entirely figure out how to properly work the widget, but found another solution that might help.
All I wanted was the selected information (Address, City, Zip Code, trash days, garbage days, etc.) to be shown in a pop up and to be directed to the location when an address is input in the search bar.
1) Instead you can create a spatial join between your classes before downloading them online.
2) Create Web App, navigate to Widget and click the edit (pencil) in the Search Widget.
3) In the top left click add search source, then feature layer and select the layer which has your spatial join and click ok.
4) Still in the Search widget edit, click on the pencil next to Search Fields and narrow down to your preferred searches.
5) In the bottom left make sure that the "Show pop-up when the feature or location is found" is enabled and click ok.
6) In the search bar click the arrow next to it and select your layer instead of the ArcGIS Service, type an address to test if the pop-up and search are correct.
This should show you a pin of the location and a pop-up of the information you selected.
- I no longer received the pop-up error using the district widget once I created a relationship using new fields that I added to the attribute table, Based off the points within the polygons run the select by location tool and create new fields in your attribute table based on those selected records, create a relationship between your new fields.
This is how I got rid up of the pop-up, but still could not get the widget to do what I wanted so I tried the solution above that worked best for me.
