Repeater is not List and does not have automatic selection
functionality. You want to have a click on the repeated item call a
handler function and then do some work.
Below is some sample code.

Goal: Display a list of items using a complex display for each item, and
have each of those items behave like a menu element and respond to a
click anywhere on the item by running a handler function.
One solution is to use a Repeater with a custom component
In the main app or component, declare the Repeater, and the click
handler function.
mx:Application ...
mx:Script![CDATA[
import MyRepeaterItem;
...
private function onRPItemClick(oEvent:Event):void
{
var xmlItem:XML = XML(oEvent.target);
}//onRPItemClick
]]/mx:Script
mx:VBox ...
mx:Repeater id=rp dataProvider={_xmlData} ...
!-- Note we pass in the entire currentItem, and define a click
handler --
MyRepeaterItem xmlItem={rp.currentItem}
itemClick=onRPItemClick(event) .../
/mx:Repeater
/mx:VBox
/mx:Application
And in the component, MyRepeaterItem.mxml:
?xml version=1.0 encoding=utf-8?
mx:HBox mouseChildren=false buttonMode=true click=onClick(event)
!-- The metadata tag below allows us to define an itemClick handler
in mxml, as in the code above --
mx:Metadata
[Event(name=itemClick, type=flash.events.Event)]
/mx:Metadata
mx:Script![CDATA[
[Bindable]private var _xmlItem:XML;
/** Setter function */
public function set xmlItem(xml:XML):void
{
_xmlItem = xml;
//do any special, non-bound ui stuff you want
}//set xmlItem
/** Getter function */
public function get xmlItem():XML
{
return _xmlItem;
}//get xmlItem
/** Outer VBox Click handler function */
private function onClick():void
{
dispatchEvent(new Event(itemClick,false); //we do not need/want
this event to bubble
}//onClick
]]/mx:Script
!-- Now declare the Item UI --
mx:Text id=lbDescription text=[EMAIL PROTECTED]
width=100% height=100% /
/mx:HBox
