Configurable List Widget- Dropdown Padding

Hello-

I've got my configurable list widget almost how i'd like it, however my dropdown lists are so crowded it's a bit of an eyesore. I'd like once you click on the dropdown menu the actual options to have more padding in between. I have been able to put padding between the different columns (rows in my example) but not the dropdown choices. 

Unfortunately, it's  not possible to style the option elements with CSS code, please note that this it not a limitation that JotForm imposes and instead it's a limitation of HTML and CSS codes instead. 

There are options to achieve that with jQuery, but JotForm does not allow to inject other code than CSS. 

Thanks. 

Thank you very much for your response!
