Collapse whitespace between results in Zone Lookup Instant App

[ZekeMI]

I created a Zone Lookup Instant app, where a user can enter an address and get back a list of various boundaries the address falls into, such as city, county, school district, etc.

In AGOL, I'm able to create popup expressions for all layers in the popup for just the first layer in the map, so it displays like a normal popup. I do this in Arcade by using the $userInput profile to get the coordinates of the address and then running an intersect on the other layers.

In Portal 11.2 and 3, the Arcade $userInput profile that I use to do this in AGOL isn't available, so I have to use individual popups for each layer. This results in relatively large whitespace between the results. Is there a way to decrease this whitespace, or emulate the AGOL look in some other way? Thanks.

l'll take a look. Looks like your popup is showing the field/attribute values is that correct? Just want to make sure I look into the proper css you can potentially use to modify this.

The popups are correct, yes. Thanks @KellyHutchins

Not sure if this will do the trick but you can try the following custom css

.esri-widget__table{
line-height:1em;
}

Thanks @KellyHutchins. How/where would I add that? I can probably find it in F12 developer tools when the app is loaded, but does that persist? Thanks, appreciate it!

[KellyHutchins]

The dev tools option is great for testing but those values do not persist. 

To persist it in the application you can paste it into the custom css panel in the configuration experience. It can be found in Theme & Layout > Theme > Custom CSS

Thanks again @KellyHutchins. That's a useful tip, but unfortunately didn't reduce the whitespace.
