My checkboxes are all going to the right. I’m on a free account so I can’t change the formatting. I’m not sure why you would want your checkboxes to go to the right by default.
I am not usre what the options are available with a free account, but if you have a LAYOUT tab, open it and look for the for the LABEL POSITION option. Make sure that the “Place labels on right…..” option is checked.
This option exists for users who are building surveys in Arabic and other right to left languages.
