简介：

The following example shows how you can create a simple ComboBox item renderer which displays multiline items in the ComboBox control’s drop down menu

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

< mx:Application xmlns:mx ="http://www.adobe.com/2006/mxml"
        layout ="vertical"
        verticalAlign ="top"
        backgroundColor ="white" >

     < mx:XMLList id ="statesXMLList" >
         < state abbrev ="AL" name ="Alabama" />
         < state abbrev ="AK" name ="Alaska" />
         < state abbrev ="AZ" name ="Arizona" />
         < state abbrev ="AR" name ="Arkansas" />
         < state abbrev ="CA" name ="California" />
         < state abbrev ="CO" name ="Colorado" />
         < state abbrev ="CT" name ="Connecticut" />
     </ mx:XMLList >

     < mx:ComboBox id ="comboBox"
            prompt ="Please select a State

"
            dataProvider ="{statesXMLList}"
            rowCount ="3"
            labelField ="@name"
            itemRenderer ="ComboBoxItemRenderer" />

</ mx:Application >

ComboBoxItemRenderer.mxml:

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

< mx:VBox xmlns:mx ="http://www.adobe.com/2006/mxml"
        styleName ="plain" >

     < mx:Label text ="{data.@name}"
            fontSize ="11"
            fontWeight ="bold" />
     < mx:Label text ="{data.@abbrev}"
            fontSize ="9"
            paddingLeft ="10" />

</ mx:VBox >
