The choiceGroupAnchorExclusive function can be used to anchor choices in a randomized choice group and/or make choices exclusive in multi-select choice group.

This function is available for a reasonable fee. Contact TomG on the Qualtrics Community to learn more.

To make the function available to all questions in the survey, copy the function to the Survey Header inside a script tag: Add the choiceGroupAnchorExclusive function to the survey header to make it available to any question in the survey. Go to Look & Feel → General → Header edit → and paste the provided choiceGroupAnchorExclusive function JS:

<script>/*Paste choiceGroupAnchorExclusive function JS here*/</script>

Alternatively, paste the choiceGroupAnchorExclusive function JS into a question's JS outside the existing Qualtrics functions to make it available to questions on the page.

To anchor a choice within the choice group, put the choice text inside a span with the class anchor. For example:

<span class="anchor">Choice text</span>

To make a choice exclusive within a choice group, put the choice text inside a span with the class exclusive. For example:

<span class="exclusive">Choice text</span>

To anchor and make a choice exclusive within a choice group, put the choice text inside a span with the classes anchor and exclusive. For example:

<span class="anchor exclusive">Choice text</span>

If there are multiple anchored choices within a choice group, exclusive choices will be anchored below non-exclusive choices.
