# jQuery Vertical Splitter

This example demonstrates the use of an outline splitbar that reduces the number of reflows required. When the mouse is used to move the splitbar, the actual splitbar is not repositioned until the mouse is released. This can improve performance significantly when the splitter contains complex content.

See the splitter documentation

This is the left side of the vertical splitter. Typically you might use this side for a navigational display of some data that is related to the right side.

Using CSS styles you can control the look of the splitter, such as its color, width, and appearance when selected. Or, you can specify most options when you call the plugin to create the splitter.

This is the right side of the vertical splitter. Usually this side will be wider than the left side, but that's up to you. The left pane of this demo was set to be 150 pixels wide in the stylesheet, which is why the right pane is initially larger. If you don't specify a width for either panes when the splitter is created, the two panes will be equal width.

The splitter plugin supports the use of the keyboard to move the splitbar via the browser's accessKey feature. To move the splitbar in IE or Firefox, press `Alt-Shift-I`, then press the arrow keys. To unfocus the splitbar, press `Tab`. In Opera, press `Shift-Esc` and then the letter `I`; remove focus with `Esc`.
