Radiobutton list aligment

Hi. I cant seem to find the CSS related to customfield radio buttons.
I need it to align under each other and not after each other.

I am also loooking for a way to list my radio buttons as a vertical list, but I use joomla 1.5.

For the radio buttons, right now, the system use Joomla core function to generate list of radio items and we could not modify it . In this case, please give me link to your site so that I can have a look at it to see whether we can modify css to meet your need .

Regards,

Tuan
