How can I add HTML to a checkbox option

Hi, in this question I can see someone add HTML code to checkbox options...

https://www.jotform.com/answers/758616-Add-sub-label-to-a-check-box-option

However this looks like an older version of JotForm, and I can't work out how to do it in the current version.

Please help! I need to add a <span> around part of the checkbox option.

Regards,

Clay

It's not possible to add HTML code to the options nor the field label, this has changed due to security reasons. The only part that seems to be still allowing HTML code is the hover text: 

Thanks.
