amandaveeenhuis,
Thanks for reaching out! I’d love to help you out here. You should be able to add some jQuery to the page in order to add CSS classes to the appropriate elements, which you can then use for styling. Try adding something like this to your functions.php file: https://gist.github.com/ckpicker/9367837
You’ll need to add a line for each option value that you want to target and customize the text that you’re searching for. Give that a shot and let me know if it does the trick. Thanks! 🙂
