The bubbleBurst function converts a Qualtrics multi-select, multiple choice question into an animated ranking or select top N question. Functionality includes:

• Supports text or image choices
• Automatically detects Rank or Top X mode based on “allow text” configuration
• Specify number of items to be ranked/selected
• Optional auto advance when last item ranked/selected
• Optional auto ranking/selection of last item when only one item remains
• Reset option
• Customize animation settings
• Customize status text

Here is a demo:

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 bubbleBurst 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 bubbleBurst function JS:

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

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

Add JS to call the bubbleBurst function to apply it to the multiple choice question as follows:

Qualtrics.SurveyEngine.addOnload(function() {
	bubbleBurst(this);
});

To override the default options, specify the desired options in the second function argument as an object. For example:

Qualtrics.SurveyEngine.addOnload(function() {
	bubbleBurst(this,{max:5,image:true});
});

At the end the question add a div with class “status” to display the status text followed by style to hide page while it loads.

Please rank the three most important items in this list below by selecting in the order of most important to least important.
<div class="status" style="padding-top:1em"></div>
<style>.Skin { opacity:0; }</style>

To enable ranking turn on “Allow Text” for each choice in the multiple choice question. If “Allow Text” is not enabled for all choices, the bubbleBurst function is in Top N (where N is max) mode.

Default: true (on)
