Flex has a Spark List control, using an IList (ArrayList or ArrayCollection) as the data provider.

Declarative approach:

Using MXML, this is implemented as <s:List>, as in:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark">

    <s:List>
        <s:dataProvider>
            <s:ArrayList>
                <fx:String>Item 1</fx:String>
                <fx:String>Item 2</fx:String>
                <fx:String>Item 3</fx:String>
            </s:ArrayList>
        </s:dataProvider>
    </s:List>

</s:Application>

Programmatic approach:

From code, a list is instantiated and added to the display list such as:

import mx.collections.ArrayList;
import spark.components.List;

var list:List = new List();
list.dataProvider = new ArrayList([ "Item 1", "Item 2", "Item 3" ]);
addElement(list);
