When we create a complex user interface, we end up with dozens of sections where
different information needs to be presented to the user. In such a scenario, space
becomes a constraint and the web page becomes unnecessary long. We can overcome
such limitations by using Collapisble Panels. It allows us to easily add collapsible/expandable
sections to our page.
The example below, shows a series of collapsible panels that you will find in most
of the sites. By using AJAX Collapsible Panel Control, we dont need to write custom
coding for hiding/showing the sections.
