How to give a "Don't Know" option?

Poppy Provo, UTFounding Community Member CEP (Chief Executive Paw-ficer)

I have a text entry question but want to give the respondents the option to select "Don't Know" instead of filling it out. I don't see a way to do this in the question options at all - any suggestions?

    The best way to set this up is to create a multiple choice question with 2 answers, the first will include a text entry, and the second will be Don't know.

    Then you can add the following JavaScript to hide the first label, while keeping its text entry box:

        Qualtrics.SurveyEngine.addOnReady(function () {
            function hideLabel(element) {
                if ('input')[0] != null ||'textarea')[0] != null) {
          'label').each(function (a, b) {
                } else {
                var hideLabelsFlag = false
                function hideLabels() { //QH.hideLabels() - Hides the label for any answer option where a text input has been added.
                    var elements = $$('.LabelWrapper');
                    elements.each(function (name, index) {
                    hideLabelsFlag = true;

    Stop! Don't do it Poppy! Qualtrics advises against including a "Don't Know" option and has a great article as reference.

    @JulieT Thanks, Julie! That is great advice, however, my supervisor is pretty adamant that they still want to add a "Don't Know" option. Does anyone know how to do this?

    @Poppy, this solution isn't pretty, but it's functional. Create a 2-option Multiple Choice question and have one of them allow text entry.

    I'm not sure how much space a text entry field will allow, but it might work??
