Hey @m_schneider 

mabey it will work with this change

 

Qualtrics.SurveyEngine.addOnload(function() {
    /* Place your JavaScript here to run when the page loads */
});

Qualtrics.SurveyEngine.addOnReady(function() {
    /* place your JavaScript here to run when the page is fully displayed */
    var firstclick = 0;

    jQuery('.handle').hide(); // Assuming '.handle' is the class of the element you want to hide
    jQuery('.track').on("mouseover", function() {
        jQuery(this).find(".handle").show();
        if (firstclick == 0) {
            jQuery(this).find(".handle").css("width", "0px");
        }
    });

    jQuery('.track').on("click", function() {
        firstclick = firstclick + 1;
        jQuery(this).find(".handle").css("width", "20px");
    });
});

Qualtrics.SurveyEngine.addOnUnload(function() {
    /* Place your JavaScript here to run when the page loads */
});
 

You are a champ! Works like a charm :)

 @RickB Sorry but do you know how to adapt this that it also works on mobile? I only see a grey bar there and no indicator of the slider ball/number it is pulled to. Would help a lot!
