Hi Scott,
You can try setting the "Render Type" property to ARIA UL -
https://www.screencast.com/t/wt2YCIytf9The Render Type property is mainly for changing how screenreaders view the DDL object, but it has a closer look to what you are trying to achieve. I would check it out on different browsers / devices since the look of the DDL is mostly controlled by the browser. If needed, we can provide some instructions on how to add some styling code to the published output so you can tailor the look of the object with more precision - it would just require some post-production edits.
