Adding a horizontal separator to a Flex PopUpButton control’s pop up menu
The following example shows how you can add a horizontal separator to a PopUpButton control’s pop up menu in Flex by setting the type attribute to “separator” in the menu’s data provider.
Full code after the jump.
<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/01/29/adding-a-horizontal-separator-to-a-flex-popupbutton-controls-pop-up-menu/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical"
verticalAlign="top"
backgroundColor="white">
<mx:Style>
PopUpButton {
popUpStyleName: myCustomPopUpStyleName;
}
.myCustomPopUpStyleName {
fontWeight: normal;
textAlign: left;
}
</mx:Style>
<mx:Script>
<![CDATA[
import mx.controls.Menu;
private var menu:Menu;
private function popUpButton_initialize():void {
menu = new Menu();
menu.dataProvider = arr;
popUpButton.popUp = menu;
}
]]>
</mx:Script>
<mx:Array id="arr">
<mx:Object label="One" />
<mx:Object label="Two" />
<mx:Object label="Three" />
<mx:Object type="separator" />
<mx:Object label="The quick brown fox jumped over the lazy dog." />
</mx:Array>
<mx:PopUpButton id="popUpButton"
label="PopUpButton with separator"
openAlways="true"
initialize="popUpButton_initialize();" />
</mx:Application>
View source is enabled in the following example.
If you happen to be using an XML (or XMLList) data provider, you could use the following code instead:
<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/01/29/adding-a-horizontal-separator-to-a-flex-popupbutton-controls-pop-up-menu/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical"
verticalAlign="top"
backgroundColor="white">
<mx:Style>
PopUpButton {
popUpStyleName: myCustomPopUpStyleName;
}
.myCustomPopUpStyleName {
fontWeight: normal;
textAlign: left;
}
</mx:Style>
<mx:Script>
<![CDATA[
import mx.controls.Menu;
private var menu:Menu;
private function popUpButton_initialize():void {
menu = new Menu();
menu.labelField = "@label";
menu.dataProvider = xml;
popUpButton.popUp = menu;
}
]]>
</mx:Script>
<mx:XMLList id="xml">
<node label="One" />
<node label="Two" />
<node label="Three" />
<node type="separator" />
<node label="The quick brown fox jumped over the lazy dog." />
</mx:XMLList>
<mx:PopUpButton id="popUpButton"
label="PopUpButton with separator"
openAlways="true"
initialize="popUpButton_initialize();" />
</mx:Application>
For an example on reducing the amount of whitespace around the separator in a Menu control, see “Adding a horizontal separator to a Flex PopUpButton control’s pop up menu (redux)”.

I think you mean vertical?
Keep up the great work!
You should call the popUpButton_initialize() on creationComplete since if the componenent is nested in some other components the initialization will silently fail.
thanks
