Flex accordion component : open multiple navigationContents at once?

Is there a way to open multiple navigation contents开发者_开发知识库 at the same time with the Accordion in Flex 4.5 ?

This isn't possible with the basic Accordion component. You'll have to create a custom component to get this kind of functionality.

Based on bill d's answer to this question:

You could try a VBox with multiple WindowShade components from the flexlib library, like in this example. You'd need to tweak the styles so it looks more accordian-like though.
