You can replace this with a single-line box that scrolls to the right as the respondent types. If the script prompts respondents for sensitive information such as a password or account number, you can request a single-line box that displays dots instead of the characters the respondent types.

The display method is referred to as the Control Type and is defined using the control keyword in the metadata section or the question’s Control.Type property in the routing section.

To determine the type of text input box displayed, place the following after the question text:

The previous example could be specified in the routing section as:
