WebExpander Flexible Expansion Direction
WebExpander lets you set the expansion to any of four directions, so you can always find the best fit to make maximum use of screen estate. Better still, the expansion modes work in complete harmony with WebExpander’s unique expand behaviors for the ultimate interactive user experience.

WebExpander Expand Behaviors
WebExpander offers two expansion behaviors: Fixed mode and Flow mode. In Fixed mode, content is hosted in a single window and selected by clicking header items, much like the familiar tabstrip control. Flow mode provides a multiple document interface approach, in which each header item has a dedicated content area.

WebExpander - Styles
WebExpander offers four predefined styles: the black and blue themes of Outlook 2007, an olive green, and the Windows 7. Use the DefaultStyleMode property to switch between them, or use WebStyleManager to create your own.

WebExpander - You Control the Content
With WebExpander you choose the content: text, graphics, or even complex forms. Full support for both inline and IFrame modes lets you to host the content directly in the control itself, or link it in from an external page – all with just a few clicks inside the Visual Studio IDE.

WebExpander - The API That Puts You in Charge
The client-side framework provides a consistent object model that supports both server-side and client-side development. A comprehensive client-side API puts you in complete control of runtime behavior. Client-side events give you the power to craft customized programmatic responses when users expand or collapse items.

WebExpander - Complete XHTML Compliance
WebExpander fully complies with the W3C XHTML standard, providing pixel-perfect rendering on any XHTML-ready browser.
