How can I add a line break between Payment Option Properties

My form (https://form.jotform.com/40305527682958 and click the 50 All-Stars option to view the payment portion) currently has the extra options on the payment field all aligned horizontally. I've searched for the fix in the forum section, but I guess I'm the first to run across this. I know I must add CSS to something or other, but I'm not quite sure of how to add a line break between each SELECT OPTION within the form-sub-label-container

Thanks for any help you're able to provide!

I've decided to just add more subitems instead, but still would like to know how this would be accomplished. The payment total also wasn't changing until I switched routes. 

Hi,

You can make the width of the field into 1/3rd of the total width of the form to have 3 columns per row.

For example:

li#id_41 {

    width: 30%;

}

li#id_42 {

width: 30%;

}

li#id_43 {

    width: 30%;

}

This css implies that the three fields will have a width that is 30% of the form. Any field after these three will then move down to the next row because there is no room in that row.

ex: If there is a Free Item #4, it would move to the bottom of Free Item #1
