Multiple choice question with "none of the above" option

I have several multiple choice questions that I also want to have a "none of the above" option that, when selected, will remove the other possible responses.

It looks like that may be possible, but I am having trouble following the directions of the support thread linked here:

https://www.jotform.com/answers/1127947-multiple-choice-question-with-none-of-the-above-option

When setting up conditions, it looks like I can only hide or disable entire questions, not individual response options. 

Also, can you explain how I can clone a question, like Sven suggests on the page linked above? I can't seem to figure out how to do that to see the conditional formatting of those example questions.

Thanks for your help-- looking forward to hearing back from you :)

Hi, I checked the thread you provided and I believe Sven just provided a workaround for the user. We do not have a feature for the Multiple Choice field to unselect the selected option if the user chooses the "None of the Above" option. You can clone the demo form of Sven to check it and test it further by following this guide: https://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL

I also created a demo form that you can check and test. Here's the link: https://form.jotform.com/81008028609958

In the demo form, I have added the Single Choice field, Multiple Choice field, and Widgets for multiple choice.

Hey John!

Thanks for your prompt reply, link to the info on cloning a field, and your example-- I was able to follow those instructions!

Unfortunately none of these options are exactly what I'm looking for. I have a long list of multiple, select all that apply options and then an option to select "none of the above" at the end of the list. Doesn't look like that is possible, so I may get some responses that are some selections from the list as well as "none of the above" and will just have to explain that in my reporting.

Thanks anyway!
