Current behavior

Currently only text fields / text boxes are supported. If you are looking to enter data with new line characters and preserve the text formatting , it is not possible.

Expected behavior

Support of some sort of toggle or expand option to existing text boxes so that they can be converted to text areas to input text with new line characters. If toggle isn't an option, maybe a new "type" that supports text area.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

When building a GraphQL trigger for project-flogo I found it cumbersome to convert the schema into one line without new line characters. Going over the schema and editing it can also becoming increasingly challenging. Ideally, most users should have the option to just copy the content of the schema and paste it into the text area and not worry about the formatting.

Please tell us about your environment:
