Form Block - Checkbox - How to add an 'Other' option

I'd like to know if it is possible to add an 'other' option to a checkbox in forms with a text field

such as...

What is your name?[ ] Bob[ ] Sam[ ] Thomas[ ] Kate[ ] Other[ If other please specify ]

I'm looking for exactly the same thing! Does anyone know how to do that?

Looking to do this as well.

The closest thing I can suggest is to create a initial hidden text input that matched with the 'other' option and show/hide based on the custom code injection
