I'm using the Zone Lookup Tool template. In the web map, I've configured a custom attribute display for the pop-up to hide fields that have blank values. This blows out the default results display in the zone lookup tool and replaces the display with the custom attribute display from the pop-up. In an attempt to maintain the same zebra-stripes table, I embedded a custom HTML table into the pop-up. The pop-up will display the table, however the table is without the zebra-stripes or alternating color on the rows. I've attached a screen shot of the zone lookup tool default results display table that I'm attempting to recreate in the pop-up. I suspect that Instant Apps has some limitations on rendering custom HTML? Any direction on how to solve this is greatly appreciated!
