Cognito-forms – Limit choice field selections in Cognito Forms

I am a developer for Cognito Forms. Currently, we have unlimited forms, unlimited fields, unlimited entries and unlimited storage. We store all of your submission data, including any uploads.

However, at some point next year we will roll out some tiered data and entry plans, which you can find out more about in our blog post.

We wanted to make our pricing very simple and representative of how much people actually use their forms. With tiered plans, free users will be limited to 100 MB of data and 500 entries per month. The first paid tier (at just $5 per month) will give them 1 GB of data and 5,000 entries per month – ten times more than the free plan.

All plans, however, will always have unlimited forms and unlimited fields.

I'm a developer with Cognito Forms. Unfortunately, a checkbox can only have two states, checked or unchecked, which equates to true or false in the context of a calculation. However, I do believe you can accomplish your requirement by using the "Radio Buttons" option for the Choice field, without it looking strange or odd. A Choice field does not require a default value therefore you do not need a third option to represent that null state. For a choice field to not have a default selection, the checkbox next to all Choices should be unchecked. I included a couple of screenshots to help explain this configuration. The first one is the configuration for the "Radio Buttons" Choice field and the second is a Yes/No field configured to be visible when the Choice field value is "Yes". I hope this helps. Hopefully, I am not misunderstanding your requirement.
