Hi @archonic08
I’m afraid we don’t have any “generic” CSS for that.
One of the options would be to switch the form’s “Design Style” in “Appearance” settings to “None” as this changes the drop-down behavior exactly the way you want it to work but that would also remove other styling so you’d need to make adjustments in colors/fonts settings and, most likely, add a bunch of CSS additionally to make the form design suit your site better. But you can try it – it’s possible that form will actually “take over” some design from your theme (that mostly depends on the theme itself).
If your form can’t be checked now and above is not an option, let us know, please, which Design Style are you actually using for the form (“default”, “flat”, “bold”, “material”?) – as set in “Appearance” settings – and we’ll try to come up with some basic solution.
Best regards,
Adam
