Create a custom component for Yes/No questions

[prestoncabe]

Probably the most common type of question on eligibility screening forms is a "Yes/No" question.

In order to create one of these in Camunda Modeler, we have to add a "Radio group" component and then update it with an options expression that maps "Yes" to true and "No" to false (the only way we know how to get the form output to be a boolean instead of a string).

This is tedious, and it is exacerbated by the fact that we cannot copy/paste existing components that we've already updated in this way.

Ideally, we would have a "Yes/No question" component available in the modeler that allows us to add these types of questions in one step.

Camunda Forms (form-js) provides the hooks necessary to do this as documented here.
