I'm creating a web map based on this example: https://developers.arcgis.com/javascript/latest/sample-code/sandbox/index.html?sample=tasks-query

Except I've modified it so that the drop-down list is dynamically populated based on the values available in an attribute column (MajBas in this instance). Everything works well EXCEPT that the pop-up content does not display properly after querying a feature. Specifically, only the pop-up title shows but not any of the content.

I'm having trouble figuring out why this would be. I'd appreciate any suggestions you may have for fixing this so that the pop-up content is visible after querying.

That was definitely it! Thank you so much for catching that. I've been combing through the documentation for popup and popupTemplate - it didn't occur to me to look at the css rules as a culprit.
