Vertical style accordion using vaadin

I am using vaadin framework, I can u开发者_运维问答se the com.vaadin.ui.Accordion library for Accordion. By default it appears in horizontal style. Is there any idea of using this style in vertical form?

Thanks

An Accordion is a TabSheet, a subclass of TabSheet, as documented in the API.

TabSheet is meant for horizontal use, Accordion for vertical use.

From http://vaadin.com/api/com/vaadin/ui/Accordion.html:

An accordion is a component similar to a TabSheet, but with a vertical orientation and the selected component presented between tabs

Do you mean you want it to be horizontal instead of vertical?
