I have a running list of values from the drop down. When I click on the
delete I need to remove the Li (it works), but also remove the value of just deleted item

<label id="2"></label>
<ul id="2" class="options">
<li id="2">John</li>
</ul>

 $(".options li").bind("click", function(){                                                                                    var ID = $(this).attr("id");                                                
$(this).parent().prev().remove();
$(this).remove();
var index = list.indexOf(ID);
list.splice(index, 1);
$("#bodyIDList").val(list);
return false;
});

you can't have duplicate ids for more than one element

make it


<label id="label2"></label>
<ul id="ui2" class="options">
<li id="li2">John</li>
</ul>

 $(".options li").bind("click", function(){                                                                                    
var ID = $(this).attr("id").substring(2);                                                
$(this).parent().prev().remove();
$(this).remove();
var index = list.indexOf(ID);
list.splice(index, 1);
$("#bodyIDList").val(list);
return false;
});

it removes all the elements from the running list rather than just one per click

if I checked 3 checkbox my running list will have 3 values, and then I want to remove 1 item it removes all items even though the value is different

 $(".options li").bind("click", function(){
                                                                  
                                                                        var ID = $(this).attr("id").substring(2);
                                                                        alert(ID);
                                                                        
                                                                         $(this).parent().prev().remove();
                                                                         $(this).remove();

ok the reqs are . I have the search routine by name. oNce i type the name i get the list of name that matches the criteria along with the checkboxes. Upon checking the checkox i put the id into running list of IDs and display selected item at the buttom (it will be multiples).

Each item of the list will have a remove button upon clicking the remove i need to remove that item from the list of selected items and update running list (remove ID of the clicked item)

For example when I selectect 3 name my html looks like this
<label id="1"></label>
<ul id="ul1" class="options">
<li id="li1">Johnnie</li>
</ul>
<label id="l2"></label>
<ul id="ul2" class="options">
<li id="li2">john</li>
</ul>
<label id="l3"></label>
<ul id="ul3" class="options">
<li id="li3">John2</li>
</ul>

My running list will be
<input id="bodyIDList" type="hidden" value="1,2,3" name="bodyIDList[]">

Once I click on the remove all values from this list get removed

 $(".options li").bind("click", function(){
                                                                  
                                                                        var ID = $(this).attr("id").substring(2);
                                                                        //alert(ID);
                                                                        
                                                                        // $(this).parent().prev().remove();
                                                                         //$(this).remove();
                                                                        $("ul[id=ul" + ID + ']').remove();
                                                                        $("label[id=l" + ID + ']').remove();
                                                                        
                                                                        //alert(index);
                                                                        var index = list.indexOf(ID);
                                                list.splice(index, 1);
                                                                         $("#bodyIDList").val(list);
                                                                        return false;
                                                                    });

your code that you have posted above is quite different from what i had suggested in other question. You don't want to refresh entire list again, when any option is deleted or checkbox is checked??
