Form Input Textarea
The Form Input Text Area Steptype is an extension of the Form Input Text Steptype. The Configuration Possibilites will be exactly the same here. The only difference is the extension from a single line input to a textarea of variable size. Within the Form Tab the Textarea Rows and Textarea Cols can be defined.
As noticeable in the bottom right corner of the textarea in the screenshot below, these parameters are only the starting value and the textarea can be resized by the participant. The textarea can not be drawn smaller than the inital values though.
