I have created a content type and one of the fields needs to be a single checkbox. For example, I could have a label - Full driving licence - and a checkbox beside it.

So I created a field with the options -
Field: List(text)
Widget: Check boxes/radio buttons

and entered a single allowed value - Full Driving License.

But this is giving me two radio buttons to choose from -
N/A
Full Driving License

So how do I fix this? It should show just a checkbox for Full Driving License, there should be no radio buttons, and no N/A option.

Hi ltwinner

Two solutions here:

1) Create a Boolean field .... that's Yes or No
2) Make your current field required .... that will remove the N/A option

OK, I made my current field required and it just gave me a single radio button that is already selected that I cant unselect. Do I have to do something else to make it a checkbox?

I would have imagined that this kind of functionality would be possible with drupal. Every 'Remember me' checkbox when you log into any website uses this functionality...

You can make it check boxes by making "Number of values" more than 1 while defining the field.

This worked for me in D8. Thanks.

For info, this is set in the "BaseFieldDefinition::create" and the method needed is:

->setCardinality(FieldStorageDefinitionInterface::CARDINALITY_UNLIMITED)

(you can set any number as cardinality or use the above for unlimited values)
