A simple plug-in that implements multiple selections in a drop-down box is more portable_jquery

(function(){

$.fn.extend({
checks_select: function(options){
jq_checks_select = null;
$(this).val("---Please select---" );
$(this).next().empty(); //Empty first
$(this).unbind("click");
$(this).click(function(e ){
jq_check = $(this);
//jq_check.attr("class", "");
if (jq_checks_select == null) {
jq_checks_select = jq_check.next() ;
jq_checks_select.addClass("checks_div_select");
//jq_checks_select = $("").insertAfter(jq_check);
$ .each(options, function(i, n){
check_div=$("" ).appendTo(jq_checks_select);
check_box=check_div.children();
check_box.click(function(e){
//jq_check.attr("value",$(this).attr( "value") );

temp="";
$(this).parents().find("input:checked").each(function(i){
if( i==0){
temp=$(this).val();
}else{
temp ="," $(this).val();
}
});
//alert(temp);
jq_check.val(temp);
e.stopPropagation();

});
jq_checks_select.show ();

jq_checks_select.toggle();

}
e.stopPropagation();

$(document).click( function () {
flag=$("#test_div");

jq_checks_select.hide();
