Hello, my multiselect box is already selected, but I didn't do it....

[chgm1006]

in this Image,
you can see my multiselect box is already one item selected.

but I just wrote no selected-select box.

// Sub SelectBox
var size2 = <%=splitSubSection.length%>;
var strSubCode = "<%= strSubCode.toString()%>".split("|");
var strSubSection = "<%= strSubSection.toString()%>".split("|");
for (var i = 0; i < size2; i++) {
$("#subSection").append($("").attr("value", strSubCode[i]).text(strSubSection[i]));

I made my select box by Jquery like above. I didn't check any option.

and I used multiselect box like this,

        var warning = $("#message");
        $("#subSection").multiselect({
            click: function(event, ui){

                if( $(this).multiselect("widget").find("input:checked").length > 8 ){
                    warning.addClass("error").removeClass("success").html("8개까지만 선택 가능 합니다.!");
                    return false;
                } else {
                    var idx = 8 - $(this).multiselect("widget").find("input:checked").length;
                warning.addClass("success").removeClass("error").html(checkedValues.length ? checkedValues.join(',') : 'Please select a checkbox');
                    values = checkedValues.length ? checkedValues.join(',') : '' ;
                }

            }

        }); 

Could you please any help for me?

You probably forgot to add the multiple attribute on the select box. Without it browsers will automatically select the first item.

Thank you very much.
You're right. I forgot it.
It works well.
