Form Designer: Other option does not have custom radio button or checkbox styleAsked by ksemyanov on February 17, 2016 at 01:25 AM
Form designer doesn't allow to change the style of "Other" option for radio buttons.
You can see this bug on the second page of this form: https://form.jotformeu.com/60325367984363
Thanks for reporting. We'll raise that to our higher ups for a resolution.
For now, you can sort it out by injecting this CSS code to your form. This should add the same styling on the other radio button. Please take the CSS codes here http://pastebin.com/raw/BgTFf5Nx
