The Multi Layout Regions component is based on the Ajax programming style. This means that extra data is requested from the server and loaded in the background without interfering with the display and behavior of the existing page. Entire Web pages do not have to be reloaded each time there is a need to fetch data from the server.
A Multi Layout Region is a container you use to group Layout Regions in a defined area on the page. Multi Layout Regions are page segments that you can place, size, and control independently from the rest of the page.
There are five key aspects to using Multi Layout Regions:
When you move a Multi Layout Region on the page, its embedded Layout Regions move with it, and maintain their positions relative to each other and the Multi Layout Region.
You can send cascading action messages to the Multi Layout Region, and it will pass the message to all layout regions embedded within it. See Building Dynamic Pages.
You can embed a Layout Region within a text box. This gives you position based placement of the layout regions within the Multi Layout Region, while the rest of the page is arranged in a text-based layout.
You can assign an HTML output method to a Multi Layout Region independent of the method used for its parent Layout. See Setting the HTML Output Method for a Multi Layout Region.
You can position content with pixel level precision by dragging it into place in the container.
To create dynamic pages and make them richer and more interactive for the users, you can display the Layout Regions of a Multi Layout Region navigating with different types of tab controls. Tab Controls are page elements, such as accordions and tabbed panels that make your page more interesting and interactive. There are several types of navigation structure among Layout Regions of the Multi Layout Regions.
A Multi Layout Region can be placed either on the Page Layout or on the MasterBorder. You can add as many Multi Layout Regions to a page as you want.
