Spark List Itemrenderer items outside of List

Question

I have a spark list and i want some of the items in it to appear out side of the list depending on the users interaction.
Is there a way to make items of an item renderer appear outsid of the LIst container?
When i use basic layout on the lsit and explicitly set the x and y, they appear behind the list.
Thanks.

Hi jmandawg,
My ListRenderer.mxml may be what you want as follows,
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer 
xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="
library://ns.adobe.com/flex/spark" xmlns:mx="
library://ns.adobe.com/flex/mx" hide="mOut(
null)" mouseMove="mOut(event)" mouseOut="mOutValueItem(event)"mouseDownOutside="mOut(event)" creationComplete="inited()"
autoDrawBackground="
true">
<fx:Script>
<![CDATA[
import mx.controls.TextInput; 
import mx.managers.PopUpManager; 
import mx.utils.StringUtil; 
import flash.text.TextLineMetrics; 
public var mouseOnPopup:Boolean = false;  
public var vi:mx.controls.TextInput; 
private function inited():void {vi =
new mx.controls.TextInput();vi.editable=
false;vi.addEventListener(MouseEvent.MOUSE_OUT, mOut);
vi.addEventListener(MouseEvent.ROLL_OUT, mOut);
vi.addEventListener(MouseEvent.MOUSE_OVER, mOverPopup);
private function mOut(event:MouseEvent):void { 
if ( vi.isPopUp ) {PopUpManager.removePopUp(vi)
mouseOnPopup =
false;}
private function mOverPopup(event:MouseEvent):void {mouseOnPopup =
true;}
private function mOutValueItem(event:MouseEvent):void { 
if ( vi.isPopUp && !mouseOnPopup) {PopUpManager.removePopUp(vi)
private function mOver(event:MouseEvent):void { 
var txt:String = itemValue.texttxt = StringUtil.trim(txt);
if(txt.length<5) return; 
if(!vi.isPopUp) {PopUpManager.addPopUp(vi,
this.parent)vi.text=txt;
vi.setStyle(
'fontSize',18); 
var txtMetrics:TextLineMetrics = vi.measureText(vi.text);vi.width=txtMetrics.width*1.2
vi.height=itemValue.height*1.4
var p:Point = itemValue.localToGlobal(new Point(itemValue.x, itemValue.y));vi.x=p.x;
vi.y=p.y-10;
]]>
</fx:Script>
<s:TextInput id="itemValue" text="{data.value}" width="200" mouseOver="mOver(event)" mouseOut="mOutValueItem(event)" mouseMove="mOut(event)" editable="false"/> 
</s:ItemRenderer>
You may test it with the following in your main.mxml
Bindable] 
private var detailAC:ArrayCollection = new ArrayCollection([{value:"nteDevice.device"},{value:
"nteDevice.deviceTypenteDevice.loopbackIpAddr"},{value:
"nteDevice.ipAddressnteDevice.loopbackIpAddr"},{value:
"nteDevice.loopbackIpAddrnteDevice.loopbackIpAddr"}, {value:
"nteDevice.release"},{value:
"nteDevice.releasenteDevice.loopbackIpAddr"},{value:
"nteDevice.clli"},{value:
"nteDevice.provisionStatus"}]);
 <s:List id="lst" itemRenderer="com.att.ntscp.view.component.ListRenderer" dataProvider="{detailAC}" width="200" height="200"/>
Is it a little bit trick?
