How to add reset button in the Question

ricsdpl
This would be quite difficult as for each question type a different JS would be needed it would make it more complicated.
My suggestion would be to don't go ahead with it as if at all you create that button and in future you change the question type you will have to change the button as well.
Hope it helps!

This should work for most questions:

Qualtrics.SurveyEngine.addOnReady(function () {
    const quest = this;
    const qc = quest.questionContainer;

    qc.querySelector(".QuestionText").insertAdjacentHTML("afterend", "Clear/Reset");

    qc.querySelector(".reset").onclick = function () {
        qc.querySelectorAll(".q-checked").forEach((item) => {
            item.classList.remove("q-checked");
        });
        qc.querySelectorAll("select").forEach((item) => {
            item.clear();
        });
        qc.querySelectorAll(".InputText").forEach((item) => {
            item.value = "";
        });
    };
});
