How to Layout Components

Taking Web Pages to a Higher Dimension with Ajax

The content in a static web page is bounded by its page size and its layout; introducing new information to a static web page means redirecting to a new page. With Ajax, new information and presentation could be dynamically loaded onto a page by replacing pieces of the existing DOM elements, making an Ajax enabled web page analogous to having a higher order of dimension then a traditional HTML page. A clear illustration of that is the tabs (Tabbox) widget, which allows document content to be stacked up in an area with fixed size on a single page. In the table below, we summarize the Ajax elements enabling us to this additional degrees of freedom in page layout:

Ajax Element Usage Demo
Overlay Stack contents up in a fixed area on the same page [Tabbox]
Folding Allow "show and hide" for contents dependent on other contents [Hierarchical Grid], [Master Detail],
Pop-up Allow contents contained in an area to be evoked on top of its parent page with its position adjustable [Modal Window], [Pop-ups],
Collapsible / Closable Allow contents to be hidden so page space is disclosed [Portal Layout], [Border Layout]
Splittable Allow the contents area size to be adjustable [Splitter], [Border Layout]

ZK offers a variety of layouts to meet the demands of building diverse web applications.
