Hi Peter
The demo you refer to shows how a horizontal splitter (contentSplitter) is nested in the righthand panel of a vertical splitter (mainSplitter). That use case works fine. But if the use case is that you want to have a west-center-east or north-center-south layout, then you want both splitters to change the size of the center panel (and collapse the north or south panel) only. Or put differently, when one splitter-bar is moved all others stay put, which is a usual behaviour if you build a workbench kind of application. But with nested splitters it doesn’t work like that. For example try resizing panel 4 using the splitter on its top in the demo . Other frameworks allow you to define more that two panels inside a splitter. It would be nice to have that in jQWidgets too.
