Multi Layout Regions components offer you the possibility to add Ajax functionality to your Web pages. By using the Multi Layout Regions components, you increase the speed and usability of your Web pages by updating only a part of the page at a time, rather than requiring the entire page to be reloaded after a user initiated change. Through the power of Ajax, the Multi Layout Region components are containers for the layout regions that you place on your pages. By using Multi Layout Regions, you avoid a complete refresh of a page. You may add multiple Layout Regions to a Multi Layout Region and you can change their content by refreshing only that part of the page using the navigation elements. You can place far more Layout Regions on the Multi Layout Regions because the Layout Regions are placed on sets of overlapped Layout Regions.
