I am using version 1.5.1.1. I have been trying for several weeks to get this to work. I have searched for the forum and tried some similar suggestions. I have reinstalled Gravity Forms from scratch on my hosting site several times. The plugin folder name is the default. I should be using the correct CSS file since I've reinstalled, right? I saw a post where someone said that even though the latest version was installed it was pulling from an old CSS file that doesn't contain the ready classes. I don't know what else to try. I have a checkbox list that is fairly long and I'm trying to use the ready class gf_list_2col. Every time I enter the class name, it disappears upon saving the form. Is it supposed to do that? I never see 2 columns in preview or on the page itself. My site is in maintenance mode so you'll probably need to login to troubleshoot. Let me know where to send the login info.
