There are more appropriate plugins, based on jQuery to obtain what you want.
OPTION 1:
I personally used in a my project UI Layout.
It is an almost old project (6 years ago), but in mid-2014 its development is re-started, even if there are no more information after september 2014.

OPTION 2:
If you need a more complete solution, you could think about jEasy UI, that is a complete framework that

It is a sort of replacement of jQuery UI, with some similar widgets (dialogs, accordions, ...) and something exclusive, like Layout module, already linked in my answer.
OPTION 3: Analogue solution to the previous one, is Zino UI, another complete UI framework that has a specific component dedicated to "Split Layout"
OPTION 4: jQWidgets is another library, with similar purposes of previous ones, and specifically could be interesting jqxSplitter module.

There is also another alternative, that allows to slice panels in the browser windows but in addition allows to drag&drop single panels creating different tabs, and side-by-side sub-windows.
This is called Golden Layout. It's different from previous ones, for many reasons also more powerful but surely at the moment it has not Touch support...
