@RaghuA Which layout are you using?

Multiple choice with multiple answers that are listed vertically.

Based on the existing values in the embedded data field as shown above, I want the appropriate radio buttons to be checked.   Hope that makes sense!!

@RaghuA are you looking to pre-select the choices based on an embedded data, if yes then please check out a similar post.

@RaghuA This code works for me with classic layout: 

Qualtrics.SurveyEngine.addOnReady(function()
{
	var dataClassification = "${e://Field/DataClassification}"; 

	// Split the embedded data into an array
	var options = dataClassification.split("|");

	// Get the <ul> element containing the choices
	var questionBody = document.getElementById(this.questionId);
	var choiceStructure = questionBody.querySelector(".QuestionBody .ChoiceStructure");

	// Iterate through each <li> element
	var liElements = choiceStructure.querySelectorAll("li.Selection");

	liElements.forEach(function(li) {
		// Find the label text
		var labelText = li.querySelector("span.LabelWrapper label span").textContent.trim();

		// Check if the label text is in the options array
		if (options.includes(labelText)) {
			// Select the corresponding radio button
			var inputElement = li.querySelector("inpututype='checkbox']");
			inputElement.checked = true;
		}
	});
});

Embedded data is defined before the question: 

That’s how it gets loaded: 

Please consider that this does not work if the texts of the multi select options are translated.

@RaghuA Should not be due to the JavaScript but rather the question setup itself… There are plenty of community topics already when you search for “You are only allowed to use a subset of HTML markup tags.”. 

@chackbusch - Yes, you were right!! The account manager was able to turn the html permission on and that seemed to fix the issue of being able to save the code snippet.  Thanks for your help.
