Sree,

You can create an ItemRenderer based on any UIComponent and add your states into that. Then assign that ItemRenderer to your List. I have started working on an example. This is not complete because it doesn’t handle selecting an item. But it should be a good starting point.

DynamicListItemRenderer.mxml:

<?xml version="1.0" encoding="utf-8"?>

<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" borderStyle="solid" backgroundColor="0xFFFFFF"

verticalGap="-2" cornerRadius="4" borderColor="0x000000"

rollOver="currentState='expanded'" rollOut="currentState=''">

<mx:transitions>

<mx:Transition fromState="*" toState="*">

<mx:Resize target="{this}" duration="300"/>

</mx:Transition>

</mx:transitions>

<mx:states>

<mx:State name="expanded">

<mx:AddChild creationPolicy="all">

<mx:Label text="{data.desc}"/>

</mx:AddChild>

</mx:State>

</mx:states>

<mx:Label text="{data.label}"/>

</mx:VBox>

Main.mxml:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*" width="600" height="500" preinitialize="initList()">

<mx:Script>

<![CDATA[

import mx.collections.ArrayCollection;

[Bindable]

public var dataList:ArrayCollection;

public function initList():void

{

dataList = new ArrayCollection([{label:"One", desc:"The US won the game on a last second goal"},

{label:"Two", desc:"The pressure was too much to overcome"},

{label:"Four", desc:"Look for exciting matchups"}]);

}

]]>

</mx:Script>

<mx:List id="mainList" itemRenderer="DynamicListItemRenderer" variableRowHeight="true"

width="100%" height="300" dataProvider="{dataList}"/>

</mx:Application>

Subject: [flexcoders] States within List

Is it possible to create states within a List that changes height on select?

Basically, I need to switch between a simple and advanced view in a list only on select.

I tried using a Repeater in a VBox, but navigating up and down using arrow keys is not possible(?) when using a repeater.

Any guidance is appreciated.

Thanks

Sree
